Effective energy utilisation with the excavator wheel

Abstract: The optimum utilisation of energy supplied to the excavator wheel rests upon the optimisation of mode parameters of breaking aimed at diminishing the energy demand of the mining process at keeping theoretical efficiency. With bucket wheel excavators, the mining process is subject, similarly to any process in the course of which rock breaking takes place, to general regularities influencing the final effect. Then, theoretical conclusions and practical results can be applied that have been verified in the operation of drilling units and tunnelling machines, in the course of which a considerable energy and thus also economic saving was made by the regulation of mode parameters of breaking. The solution proposed is based on the determination of basic dimensions of the cut mined, especially the width-depth ratio according to the criterion of minimum specific energy by volume.

Temperature picture of a bucket tooth and its’ service life

Abstract: The shape and the geometry of a bucket edge, its material and the material of a mechanical tooth are the key influences on the efficiency and energetic demands of mining processes with bucket wheel excavators. If the excavator units are often changed due to wear or breaking down, it increases the cost of the mining process, of course. It also reduces the service life of the machine and therefore it reduces the efficiency of the whole technological unit [TU] as well. Consequently, all wear causes not only changes to the shape and geometry or material features of the digging unit, but it also increases energy demands of the mining process, as mentioned. The presumption is – increased wear of digging units raises cutting resistances and consequently the temperature goes up due to higher friction and wear. Therefore, the picture of the temperature is the scale for measuring wear.

Application of GPS to the excavator wheel

Abstract: For disintegration process control we need a quantity that respects objectively rock-disintegrating tool interaction with the elimination of human factor. From this, basic requirements for the evaluation quantity given below follow: is available in advance or at the moment of disintegration, minimises the influence of human factor on the resultant effect, evaluates objectively the disintegration process. A measure of efficiency of any disintegration process is the consumption of energy usually related to the unit volume of disintegrated rock; on the basis of analysis of done theoretical and practical researches orientated towards the disintegration processes and the verification of objectivity when used in situ (in drilling and tunnelling), at present it is minimised specific volume energy that is the most objective evaluation quantity. This quantity has a general validity for dispersion processes, and thus its use even for the evaluation of diggability on the digging wheel of excavator has a rational basis. In connection with the GIS application for controlling the extracted quantity, an optimal tool is offered for the maximum efficiency of excavation process.

Regional transportation – reactivation
Abstract: Passenger quantity histogram was used to measure the character of passengers’ migration, pick commuter times, equal intensity and minimal commuter numbers. The measurement was done pre and post changes introduced to the train timetable for both working days and weekends (Saturdays and Sundays). The small numbers of passengers made this connection unsustainable without substantial financial support from the government. The changes introduced to the timetable failed to generate increased demand for the service. The Pareto chart clearly illustrates the changes introduced to the timetable over the period of this research. Other disadvantages of the new timetable were also pointed out in this paper.

Efficiency increasing of belt conveyor’s drive by ceramic lagging of driving pulley
Abstract: In any point of the belt contact with the drum a relative speed compensation takes place that is carried out by a slippage even when the relevant contact spots are fairly clean and dry. This leads to heat generation that is being absorbed by both materials involved – by the belt as well as by the drum. Unlike the belt, the drum lagging would increase its temperature up to a certain limit that depends on number of factors. When the lagging surface temperature is reaching appx. 60°C some structural changes in the lagging material take place and further rise of temperature can create a risk of belt inflammation and destruction of the driving unit. This can be avoided by lagging the drum with new materials that eliminate any friction on the contact surfaces and that are heat resistant.

Normal distribution of variables is one of inevitable conditions for the analysis, examination, and improvement of the manufacturing processes (f. e.: manufacturing process capability) although, there are constantly more approaches to non-normal data handling. An appropriate probability distribution of measured data is firstly tested by the goodness of fit of empirical distribution with theoretical normal distribution on the basis of hypothesis testing using programme StatGraphics Centurion XV.II. Data are collected from the assembly process of 1st row automobile seats for each characteristic of quality (Safety Regulation -S/R) individually. Study closely processes the measured data of an airbag´s assembly and it aims to accomplish the normal distributed data and apply it the statistical process control. Results of the contribution conclude in a statement of rejection of the null hypothesis (measured variables do not follow the normal distribution) therefore it is necessary to begin to work on data transformation supported by Minitab15. Even this approach does not reach a normal distributed data and so should be proposed a procedure that leads to the quality output of whole statistical control of manufacturing processes.
Key words: quality, statistical control, hypothesis testing, probability distribution, normality, data transformation

Managing the acoustic climate in local government units – a new approach
Abstract: The paper presents a new approach to shaping acoustic comfort as a process of managing the acoustic environment in urbanised areas. The research in this area focuses on the psychoacoustic aspect of shaping acoustic comfort in an urban environment. This approach permits, depending on the purpose of land, not only to reduce the noise to the allowable limits but also to evaluate the acoustic quality of sounds originating in different sources. In this context, a review was performed of the research carried out on identifying soundscapes as a way of shaping acoustic comfort in the urban environment.
In this paper it is suggested that the entropy method be used for the assessment of auditory sound perception. The research carried out by the author shows that linking the relationship between the quality of perceived sounds with the elements/factors which shape the acoustic environment can be used to valorise soundscapes.

Technology assessment in engineering practice. The case of Bioliq® – fuel production from biomass
Abstract: This paper includes a brief overview of the basic motivations and objectives of TA, followed by a description of the three main operating fields of TA: providing scientific advice for decision-making in the political system, contributing to public debate, and enriching technology development and engineering practice. These issues will then be considered in more detail by referring to various approaches to the relationship between TA and technology development and by presenting a specific case study of an accompanying TA process over various development stages of the bioliq® process for converting dry biomass into fuel (Bio-mass to Liquid) and chemicals. The accompanying TA work on the bioliq® process can, as a result of more than ten years of experience, be considered a successful technology assessment as it has opened up a new research field with a highly precautionary aspect on the one hand, and helped to win over technology-oriented research institutes to reorienting their research work, on the other. The results of the TA studies allowed to assess e.g. the competitiveness of the bioliq® process at a very early stage. The mutual trust built up in the course of the historical development between the parties involved has always been essential for this ongoing ac-companying TA process. TA has been proven, in this way, a useful tool to uncover new chances for engineering research and development, and to accompany the research process.

Some observations on the design of noise barriers
Abstract: The issue connected with effectiveness of noise barriers has been the subject of numerous considerations among acousticians. On the one hand, noise barriers are still the most popular and the most frequently used protection against traffic noise, on the other hand, however, the excessive number of noise barriers and the results of research focusing on effectiveness of the existing barriers make us reflect whether it is reasonable to use them. Very often low effectiveness of noise barriers is related to a badly conducted designing process. This article presents the basic mistakes made by noise barriers’ designers and the consequences thereof. Next, the paper describes the appropriate approach to the process of the noise barriers’ design which consists in the use of computer methods and conducting of a detailed analysis of the acoustic field’s distribution both behind the barrier and on the facades of the acoustically protected buildings.

Synchronization of national grid network with the electricity ships network in the "shore to ship" system
Abstract: ‘Shore to ship’ system – ships’ power supply from the local electrical substations – is one of the effective ways to limit the negative impact of the ships lying in ports on the environment. Energy infrastructure of the port installation necessary to provide ships with power supply has to be designed so that different types of ships can use it. The important issue concerning ‘shore to ship’ system is the quality of power supply. This can be achieved via sustaining continuity of power supply while switching from the ships’ electrical network over to the national grid. In this article the author presents the way of synchronizing the national grid with the ships’ electrical network during ship’s lying in port. Such synchronization would allow for uninterruptible work of the ship’s electrical devices.

Mathematical model of attitude control bucket-wheel excavator
Abstract: This lecture deals with the application problems of convertibility GPS system at paddle excavator K 800. The claims of the modern operating surface mining of the excavators requires a lot of information for monitoring of mining process, capacity mining, selective extraction etc. The utilization of monitoring the excavator setting by GPS system proved to be the only one proper because the receivers are resistant to the vibration, dust, temperature divergence and weather changeable. Only the direct contact with communications satellite is required. It means that they can´t be located in a metal construction space (shadow caused by construction elements, influence of electrical high voltage cables) even they can´t be located close to the paddle wheel on the paddle boom (shadow possibility caused by cutting edge created during lower gangplanks mining). This is the reason that GPS receivers are set uppermost on the metal construction excavator and the mathematical formulation is required for determination of paddle wheel petting. The relations for calculation of the paddle wheel coordinate were defined mathematically and after that the mathematical model was composed.

The preliminary analysis of distribution of the velocity field and air pressure flowing throught the mining headings with different geometry of cross-section
Abstract: The basic meaning for the security of persons working in underground mining heading heir ventilation of headings. Providing the fresh air into the active mining heading is a fundamental task of ventilation service in the mine. Very significant impact on the efficiency of the ventilation process has the physical parameters of supplied airflow, such as its amount, speed and pressure. These parameters can be determined based on the "in situ" tests or modeling tests. Carrying out the tests in underground conditions is very expensive and not always available due to exploitation. As an alternative, in such cases the modeling tests can be used, which give more possibilities of analysis the impact of differentials factors on the studied parameters. In the paper there is presented results of modeling of airflow in mining heading, obtained basing on the numerical simulations with use of finite volume method in ANSYS Fluent software. The physical models of headings were prepared basing on the real cross sections of the dog headings. To find the solution of the mathematical model, the k-ε turbulence model was used.

The use of AHP method in the multi-criteria task solving  - case study
DOI 10.12914/MSPE-07-01-2014
Abstract: In the decision-making process, both single- and multi-criteria tasks are dealt with. In the majority of cases, the selection of a solution comes down to determination of the “best” decision (most often based on the subjective assessment) or to organisation of the set of decisions. The Analytic Hierarchy Process (AHP) is one of the methods used for evaluation of qualitative features in the multi-criteria optimisation processes. This article discusses the possibilities of using the above-mentioned method, illustrated with an example of purchasing technical equipment for one of the municipal landfill sites in the Silesian Province.

Context-driven Maintenance: an eMaintenance approach
DOI 10.12914/MSPE-05-03-2014
Abstract:
All assets necessarily suffer wear and tear during operation. Prognostics can assess the current health of a system and predict its remaining life based on features capturing the gradual degradation of its operational capabilities. Prognostics are critical to improve safety, plan successful work, schedule maintenance, and reduce maintenance costs and down time. Prognosis is a relatively new area but has become an important part of Condition-based Maintenance (CBM) of systems. As there are many prognostic techniques, usage must be attuned to particular applications. Broadly stated, prognostic methods are either data-driven, rule based, or model-based. Each approach has advantages and disadvantages; consequently, they are often combined in hybrid applications. A hybrid model can combine some or all model types; thus, more complete information can be gathered, leading to more accurate recognition of the fault state. This approach is especially relevant in systems where the maintainer and operator know some of the failure mechanisms, but the sheer complexity of the assets precludes the development of a complete model-based approach. The paper addresses the process of data aggregation into a contextual awareness hybrid model to get RUL values within logical confidence intervals so that the life cycle of assets can be managed and optimised.

The supporting of exploitation and maintenance management within networked technical systems

DOI 10.12914/MSPE-06-02-2015
Abstract: Network technical systems are complex systems, which include distribution networks with devices and engineering objects supporting their work. These kind of systems are used for media distribution, such as: drinking water, fuel, gas, heat, etc. One of specific features of this system is large territorial dispersion of technical objects within the system. The exploitation specificity of networked technical systems requires a special approach for implementing maintenance and repair work, taking into account the large territorial dispersion of their components and limited access to technical infrastructure. The features pointed above show the difference between networked technical system and the typical industrial technical objects (e.g. available in manufacturing plants). This difference also requires the use of specific IT tools for maintenance management. This article discusses examples of selected tools in this class.

The method of assessing rock bursting hazard in mining

DOI 10.12914/MSPE-07-02-2015
Abstract: The article discusses a concept of forecasting accident risk during longwall extraction in crump-risk conditions. In Polish mines rock burst hazard can be described as high compared to other mines around the world. It's related to increase of depth of longwall field operation, preparation works, including drilling of mine face pavements which leads to systematic deterioration of geological and mining conditions. Depletion of coal is also the reason why mines operate in high mining tremor risk conditions. Mines more and more often operate in decks, where there is large number of edges and remains of older decks. Rocks bursts still remain one of the most dangerous natural hazards and therefore are fundamental problem and have the greatest impact on safety in mining industry. The proposed method for forecasting accidents and losses in people and goods can contribute to improvement of work organization methods and mine safety management system.

DOI 10.12914/MSPE-10-02-2015
Abstract: The study presents the implementation of projects in organisations that achieve business objec-tives through the implementation of repetitive actions. Projects in these organisations are, on the one hand, treated as marginal activities, while the results of these projects have significant impact on the delivery of main processes, e.g. through the introduction of new products. Human capital and solutions in this field bear impact on the success of projects in these organ-isations, which is not always conducive to smooth implementation of projects. Conflict results from the nature of a project, which is a one-time and temporary process, so organisational solutions are also temporary. It influences on attitudes and commitment of the project contrac-tors. The paper identifies and analyses factors which affect the success of the projects.

Minimization of vibroacoustic effects as a criterion for operation of gear transmissions in accordance with sustainable development principles 
DOI 10.12914/MSPE-02-01-2016
Abstract: In correctly functioning maintenance systems it is most important to prevent possible failures. A reduction of the vi- broacoustic effects accompanying the operation of machines and equipment, including transmissions, is among the factors that lower the probability of a failure. The paper presents the results of the research on the impact of operational factors on vibroacoustic conditions of transmissions. The factors covered by the analysis included a change in the mating conditions of gear wheels associated with the wear of tooth surfaces, operation of transmissions in subharmonic conditions of the main resonance and the temperature of the lubricating oil. The study demonstrated that it was possible to reduce the vibroacoustic effects generated by gear transmissions by changing the conditions of their operation. Based on the results obtained, it has been found that the operation of gear transmissions in accordance with the sustainable development principles requires technical services to take active measures consisting in the search for optimal operating conditions in terms of the vibroacoustic conditions.

Determination of workloads in cutting head of longwall tumble heading machine
DOI 10.12914/MSPE-08-01-2016
Abstract: The mining organ of the longwall heading machine KGS-320 with radial tools was the subject of the analysis. Coopera- tion of single knife with the mined solid rock was estimated in order to determine values of the forces and moments that might occur in the mining process and to estimate the energy consumption of the mining process. Analogous determina- tion of forces and moments values as well as energy consumption of the mining process for the whole mining organ with regard to all the knives installed. Following the thorough analysis of the solid rock mining process with the longwall tumble heading machine mining head the PC computer program simulating such organ’s mode of action has been developed. This program presents the simu- lation of the mining process in the part regarding direct contact of the cutting tool (knife) with the rock mass. The result of this simulation is force and moments distribution, which are transmitted via the mining organ (head) during one full turn (360o) and, as consequence, via whole longwall heading machine.

Addressing research design problem in mixed methods research
DOI 10.12914/MSPE-10-01-2016
Abstract: Alongside other disciplines in social sciences, management researchers use mixed methods research more and more in conduct of their scientific investigations. Mixed methods approach can also be used in the field of production engineer- ing. In comparison with traditional quantitative and qualitative research methods, reasons behind increasing popularity of mixed research method in management science can be traced in different factors. First of all, any particular discipline in management can be theoretically related to it. Second is that concurrent approach of mixed research method to in- ductive and deductive research logic provides researchers with opportunity to generate theory and test hypothesis in one study simultaneously. In addition, it provides a better justification for chosen method of investigation and higher validity for obtained answers to research questions. Despite increasing popularity of mixed research methods among management scholars, there is still need for a comprehensive approach to research design typology and process in mixed research method from the perspective of management science. The authors in this paper try to explain funda- mental principles of mixed research method, its typology and different steps in its design process.

Optimizing outcome in the university-industry technology transfer projects
DOI 10.12914/MSPE-04-02-2016
Abstract:Transferring inventions of academic scientists to private enterprises for the purpose of commercialization is long known as University-Industry (firm) Technology Transfer While the importance of this phenomenon is simultaneously raising in public and private sector, only a part of patented academic inventions succeed in passing the process of commercialization. Despite the fact that formal Technology Transfer process and licencing of patented innovations to third party is the main legal tool for safeguarding rights of academic inventors in commercialization of their inventions, it is not sufficient for transmitting tacit knowledge which is necessary in exploitation of transferred technology. Existence of reciprocal and complementary relations between formal and informal technology transfer process has resulted in formation of different models for university-industry organizational collaboration or even integration where licensee firms keep contact with academic inventors after gaining legal right for commercialization of their patented invention. Current paper argues that despite necessity for patents to legally pass the right of commercialization of an invention, they are not sufficient for complete knowledge transmission in the process of technology transfer. Lack of efficiency of formal mechanism to end the Technology Transfer loop makes an opportunity to create innovative interpersonal and organizational connections among patentee and licensee company. With emphasize on need for further elaboration of informal mechanisms as critical and underappreciated aspect of technology transfer process, article will try to answer the questions of how to optimize knowledge transmission process in the framework of University-Industry Technology Transfer Projects? What is the theoretical basis for university-industry technology transfer process? What are organization collaborative models which can enhance overall performance by improving transmission of knowledge in University- Firm Technology Transfer process?

Mines, quarries and landscape. Visuality and transformation
DOI 10.12914/MSPE-07-02-2016
Abstract:In this paper a review of two basic concepts is carried out: scenery and landscape integration, proposing a new concept: "visuality", alternative to the classical "visibility" used in landscape studies related to mining activity, which explores the qualitative aspects that define the visual relationships between observer and environment. In relation to landscape integration studies, some reflections on substantive issues are made which induce certain prejudices at the time of addressing the issue of mining operations landscape integration, and some guidance and integration strategies are formulated. In the second part of the text, a new approach to the landscape integration of mines and quarries is raised, closely linked to the concept of visuality which are based on a basic goal: the re-qualification of the place, and give innovative answers to re-qualify the place and show how to catch the opportunity in the deep transformation generated by the development of mining activities. As a conclusion, a case study is presented in the last section, the landscape integration study conducted on marble exploitations Coto Pinos (Alicante, Spain), considered the largest ornamental rock quarry in Eu- rope.

The application of a jet fan for the control of air and methane streams mixing at the excavations cross - the results of numerical simulations
DOI 10.12914/MSPE-03-03-2016
Abstract:The paper presents the results of numerical simulations into the distribution of methane concentration at the intersection of two excavations with a fan (turned on) giving the air stream to the area of the crossing. Assumed case represents emergency situation related to the unexpected flow of methane from an excavation and its mixing with fresh air. It is possible when sudden gas outburst takes place, methane leaks from methane drainage system or gas leaks out the pipelines of underground coal gasification devices. Three options were considered – corresponding to three different speeds of the jet fan. They represent three stages of fan work. First – low air speed is forced by a pneumatic fan, when electricity is cut off after high methane concentration detection. Medium speed can be forced by pneumatic-electric device when methane concentration allows to turn on the electricity. Third, the highest speed is for electric fans. Simulations were carried out in the Fire Dynamics Simulator (FDS) belongs to the group of programs Computational Fluid Dynamics (CFD). The governing equations are being solved in a numerical way. It was shown that proposed solution allows partial dilution of methane in every variant of speed what should allow escape of the miners from hazardous area.

Influence of applying additional forcing fans for the air distribution in ventilation network
DOI 10.12914/MSPE-04-03-2016
Abstract: Mining progress in underground mines cause the ongoing movement of working areas. Consequently, it becomes necessary to adapt the ventilation network of a mine to direct airflow into newly opened districts. For economic reasons, opening new fields is often achieved via underground workings. Length of primary intake and return routes increases and also increases the total resistance of a complex ventilation network. The development of a subsurface structure can make it necessary to change the air distribution in a ventilation network. Increasing airflow into newly-opened districts is necessary. In mines where extraction does not entail gas-related hazards, there is possibility of implementing a push-pull ventilation system in order to supplement airflows to newly developed mining fields. This is achieved by installing subsurface fan stations with forcing fans at the bottom of downcast shaft. In push-pull systems with multiple main fans, it is vital to select forcing fans with characteristic curves matching those of the existing exhaust fans to prevent undesirable mutual interaction. In complex ventilation networks it is necessary to calculate distribution of airflow (especially in networks with a large number of installed fans). In the article the influence of applying additional forcing fans for the air distribution in ventilation network for underground mine were considered. There are also analysed the extent of overpressure caused by the additional forcing fan in branches of the ventilation network (the operating range of additional forcing fan). Possibilities of increasing airflow rate in working areas were conducted.

The use of generating sets with LNG gas engines in “Shore to Ship” systems
DOI 10.12914/MSPE-05-03-2016
Abstract: The main sources of air pollution in ports are ships, on which electrical energy is produced in the autonomous generating sets Diesel-Generator. The most effective way to reduce harmful exhaust emissions from ships is to exclude marine generating sets and provide the shore-side electricity in “Shore to Ship” system. The main problem in the implementation of power supply for ships from land is connected with matching parameters of voltage in onshore network with marine network. Currently, the recommended solution is to supply ships from the onshore electricity network with the use of power electronic converters. This article presents an analysis of the „Shore to Ship” system with the use of generating sets with LNG gas engines. It shows topologies with LNG – Generator sets, environmental benefits of such a solution, advantages and disadvantages.

The unification of the code lists provided within the data model originating from the INSPIRE technical guidelines and the ones provided for GESUT databases in the context of potential exploitation in the mining industry
DOI 10.12914/MSPE-06-03-2016
Abstract: This study is aimed at exposing differences between two data models in case of code lists values provided there. The first of them is an obligatory one for managing Geodesic Register of Utility Networks databases in Poland [9] and the second is the model originating from the Technical Guidelines issued to the INSPIRE Directive. Since the second one mentioned is the basis for managing spatial databases among European parties, correlating these two data models has an effect in easing the way of harmonizing and, in consequence, exchanging spatial data. Therefore, the study presents the possibilities of increasing compatibility between the values of the code lists concerning attributes for objects provid- ed in both models. In practice, it could lead to an increase of the competitiveness of entities managing or processing such databases and to greater involvement in scientific or research projects when it comes to the mining industry. More- over, since utility networks located on mining areas are under particular protection, the ability of making them more fitted to their own needs will make it possible for mining plants to exchange spatial data in a more efficient way.

DOI 10.12914/MSPE-10-03-2016
Abstract: This article presents two concepts of site development for the „Dębieńsko 1” mining plant including plans for the track system. The first plan was created in 2013 year and mainly assumed the renovation of railway infrastructure, without changing its shape and configuration. In 2014 year it was resigned from realization of the first conception and there was proposed the second plan. It included changes in the existing track system and project of the new system of excavated raw material haulage. This system is successfully using in the USA and provides the better work productivity of a shunting locomotive. In this article also were indicated the advantages and the disadvantages of solutions proposed in the two projects of site development plans. It was denoted the project that has ultimately been chosen with the justifi- cation of choice.
Keywords: „Dębieńsko 1” mining plant, area development planning, site development project, output haulage, track system

Internet of Things in marketing: opportunities and security issues
DOI 10.12914/MSPE-01-04-2016
Abstract: Internet of Things (IoT) affects different areas of human activities: everyday life of ordinary citizens, work style of marketing teams, factories and even entire cities. Large companies try to implement the technology in their marketing strategy that reshapes not only communication style and product promotion but consumers’ expectations, perceptions and requirements towards companies. IoT is expected to become a huge network that will encompass not only smart devices but significantly influence humans’ behavior, in this particular case – decision making style in different phases of purchase process. Therefore, the need for comprehensive scientific research is necessary. The issue needs to be reviewed from various points of view, such as opportunities, advantages, disadvantages, legal and technical considerations. The paper is an attempt to review different aspects of using Internet of Things for marketing purposes, identify some of the major problems and present possible ways of solution.

Possibilities of effective inertisation of self-heating places in goaf of longwall in hard coal mines
DOI 10.12914/MSPE-02-04-2016
Abstract: Underground fires in coal mines belong to the most common hazards, the exposure to which frequently requires long term and costly rescue operations. It is mainly connected with the specific character of underground excavations which have limited volume. This makes the maximum permissible concentration of harmful gases rapidly exceeded and may also cause changes in air flow direction. The most certain way of improving a safety situation in Polish coal mining indus- try is taking early prevention steps. One of the prevention methods is inertisation of the atmosphere in longwall goaf. These activities rely on partial or total replacement of air or combustible atmosphere by inert gas. Thanks to them the risk of spontaneous fires hazard and gas explosion decreases. The main reason for the use of inert gases is to reduce the oxygen content to a limit which prevents further development of fire. This article presents methods for assessing inert gas to replace oxygen in the atmosphere in goaf.
Keywords: inertisation in goaf of longwall with caving, gas concentration in goaf, underground fire, fighting the fire

The adoption of the ArcGIS system to support the analyses of the influence of the mining tremors on the building object
DOI 10.12914/MSPE-03-04-2016
Abstract: Nowadays the mining companies use the Spatial Information System in order to facilitate data management, gathered during the mining activity. For these purposes various kinds of applications and software information are used. They allow for faster and easier data processing. In the paper there are presented the possibilities of using the ArcGIS system to support the tasks performed in the mining industry in the scope of the analysis of the influence of the mining tremors, induced by the longwall exploitation on the facilities construction sited on the surface area. These possibilities are pre- sented by the example of the database developed for the coal mine KWK “Rydułtowy-Anna.” The developed database was created using ArcGIS software for Desktop 10. 1. It contains the values of parameters, specified for its implementa- tion relevant to the analyses of the influence of the mining tremors on the surface structures.

Qualitative importance measures of systems components - a new approach and its applications
DOI 10.12914/MSPE-04-04-2016
Abstract: The paper presents an improved methodology of analysing the qualitative importance of components in the functional and reliability structures of the system. We present basic importance measures, i.e. the Birnbaum’s structural measure, the order of the smallest minimal cut-set, the repetition count of an i-th event in the Fault Tree and the streams measure. A subsystem of circulation pumps and fuel heaters in the main engine fuel supply system of a container vessel illustrates the qualitative importance analysis. We constructed a functional model and a Fault Tree which we analysed using quali- tative measures. Additionally, we compared the calculated measures and introduced corrected measures as a tool for improving the analysis. We proposed scaled measures and a common measure taking into account the location of the component in the reliability and functional structures. Finally, we proposed an area where the measures could be ap- plied.

Determination of the zone endangered by methane explosion in goaf with caving of longwalls ventilated on „Y” system
DOI 10.12914/MSPE-05-04-2016
Abstract: One of the most dangerous and most commonly present risks in hard coal mines is methane hazard. During exploitation by longwall system with caving, methane is emitted to mine heading from the mined coal and coal left in a pile. A large amount of methane also flows from neighboring seams through cracks and fissures formed in rock mass. In a case of accumulation of explosive methane concentration in goaf zone and with appropriate oxygen concentration and occur- rence of initials (e.g. spark or endogenous fire), it may come to the explosion of this gas. In the paper there are present- ed results of numerical analysis of mixture of air and methane streams flow through the real heading system of a mine, characterized by high methane hazard. The aim of the studies was to analyze the ventilation system of considered head- ing system and determination of braking zones in goaf zone, in which dangerous and explosive concertation of methane can occur with sufficient oxygen concentration equal to at least 12%. Determination of position of these zones is neces- sary for the selection of appropriate parameters of the ventilation system to ensure safety of the crew. Analysis of the scale of methane hazard allows to select such a ventilation system of exploitation and neighboring headings that ensures chemical composition of mining atmosphere required by regulation, and required efficiency of methane drainage. The obtained results clearly show that numerical methods, combined with the results of tests in real conditions can be suc- cessfully used for the analysis of variants of processes related to ventilation of underground mining, and also in the anal- ysis of emergency states.

Improvement of the process of implementation of new product for European market - case study
DOI 10.12914/MSPE-07-04-2016
Abstract:An inseparable element of intelligent processes is the effective use of knowledge gained from external sources and the ability to change under the influence of external factors. An example of this can be found in the process of introducing a new construction product to the EU market. It has to react to the ever-changing EU legislature and the national regulations that adapt to it. The frequently asked questions from manufacturers and importers indicate the necessity of creating a procedure that would allow for precisely explaining what the algorithm of the process looks like and what criteria must be met to introduce the new product into the construction product market. The complexity and multitude of regulations as well as the language barrier also cause other complications with the understanding of the process procedure of conduct. The graphical presentation of the algorithm should facilitate following the path of conduct in the case of introducing a new construction product into the EU market. The graphical form should allow for intuitive movement in the process and can constitute a basis for creating an interactive form.

Innovative use of quality management methods for product improvement
DOI 10.12914/MSPE-08-04-2016
Abstract: Organisations constantly look for new, innovative solutions and methods which could be used to improve their efficiency and increase the quality of their products. Identifying the causes for returns is an important issue for modern compa- nies, as returns are the cause for the increase in production costs and, most importantly, the loss of credibility in the eyes of the client. Therefore, for the company to be able to sustain or strengthen its position on the market, it has to follow the rules of quality management. Especially important is the rule of constant improvement. This rule is primarily connected with preventing errors and defects from occurring at all the stages of the production process. To achieve that, one must, among other things, use quality management tools. The article presents an analysis of causes for returns of a vibrating screen produced by a company which manufactures machinery and equipment for the extractive industry, using quality management tools such as the Ishikawa diagram and Pareto analysis. The analysis allowed for the identifi- cation of the causes of client returns which could not be previously identified, and proposing solutions for them.

Design of a test ring for the examination of mechanical properties of rolling bearings
DOI 10.1515/mspe-2017-0003
Abstract: The paper presents a design basis adopted for the construction of a test facility for the rig testing of rolling bearings. One of the methods of inspection of the bearings is the testing of the bearings as components having already been mounted in a specific machine component unit and tested in the conditions of operation of the unit as a whole. This article presents preliminary engineering requirements and the design of a special test rig for the examination of rolling bearings without the necessity of mounting the bearings in a specific machine component unit. The rig testing is widely used in consideration of numerous good points of such a method. The simulation testing of bearings (on test rigs) consists in reproducing as accurately as possible the real conditions of operation of the bearings when mounted in the device for which they are intended. The rigs used for such tests are complicated and expensive, but the results of such tests are more “reliable” and more accurately represent the impact of various operational factors (loads) on the durability of the bearings under test.

On the necessity of changes in the strategy of utilization ship boiler technical maintenance in the aspect of LNG applied as fuel
DOI 10.1515/mspe-2017-0004
Abstract: Heavy oils (HFO fuels) used on ships play a part in degradation of technical condition of heat exchange surfaces of utilization boilers especially on the exhaust gas side. Presence of sulphur in these fuels is the main factor favouring degradation. The upper limit for sulphur content in the fuel used outside the SECA areas equal to 3.5% is currently in force, at least until the year 2020 or 2025. The recommended by classification societies overhauls of utilization boilers are, therefore characterized by a specially chosen strategy thanks to which it is possible to maintain their appropriate technical condition. The requirement to use fuels with low sulphur content (LSFO), which are significantly more expensive than MDO fuels, in the areas of controlled sulphur emissions also led to a further introduction of alternative fuels, such as methanol and above all liquefied natural gas (LNG), onto ships. That is especially valid for the ship owners whose vessels e.g. ferries sail mainly within SCECA This article analyses the consequences of the introduced fuel change on utilization boiler maintenance. A change in the technical condition maintenance strategy for utilization boilers has been suggested.
Keywords: utilization boiler, technical condition, maintenance strategy, gas as a ship fuel

Comparative study of light sources for household
DOI 10.1515/mspe-2017-0005
Abstract: The article describes test results that provided the ground to define and evaluate basic photometric, colorimetric and electric parameters of selected, widely available light sources, which are equivalent to a traditional incandescent 60-Watt light bulb. Overall, one halogen light bulb, three compact fluorescent lamps and eleven LED light sources were tested. In general, it was concluded that in most cases (branded products, in particular) the measured and calculated parameters differ from the values declared by manufacturers only to a small degree. LED sources prove to be the most beneficial substitute for traditional light bulbs, considering both their operational parameters and their price, which is comparable with the price of compact fluorescent lamps or, in some instances, even lower.

Prediction of a newbuilding proce of the bulk carriers based on gross tonnage GT and main engine power
DOI 10.1515/mspe-2017-0006
Abstract: The paper presents mathematical relationships that allow us to forecast the newbuilding price of new bulk carriers, based on data concerning vessels built in 2005-2015. The presented approximations allow us to estimate the price based on a gross tonnage capacity and a main engine power The approximations were developed using linear regression and the theory of artificial neural networks. The presented relations have practical application for estimation of bulk carrier newbuilding price needed in preliminary parametric design of the ship. It follows from the above that the use of artificial neural networks to predict the price of a bulk carrier brings more accurate solutions than linear regression.

Biosurfactants’ production from renewable natural resources: example of innovativeand smart technology in circular bioeconomy
DOI 10.1515/mspe-2017-0007
Abstract: A strong developed bio-based industrial sector will significantly reduce dependency on fossil resources, help the countries meet climate change targets, and lead to greener and more environmental friendly growth. The key is to develop new technologies to sustainably transform renewable natural resources into bio-based products and biofuels. Biomass is a valuable resource and many parameters need to be taken in to account when assessing its use and the products made from its. The bioeconomy encompass the production of renewable biological resources and their conversion into food, feed and bio-based products (chemicals, materials and fuels) via innovative and efficient technologies provided by industrial biotechnology. The paper presents the smart and efficient way to use the agroindustrial, dairy and food processing wastes for biosurfactant’s production. Clarification processes are mandatory to use the raw substrates for microbial growth as well as biosurfactant production for commercial purposes. At the same time it is very essential to retain the nutritional values of those cheap substrates. Broad industrial perspectives can be achieved when quality as well as the quantity of the biosurfactant is considered in great depth. Since substrates resulting from food processing, dairy, animal fat industries are not explored in great details; and hence are potential areas which can be explored thoroughly.

Ecological growth boundaries
DOI 10.1515/mspe-2017-0008
Abstract: The trends of the society for the continuous growth, combined with the demographic changes, today have led to the important ecological problems on a global scale, which include, among others: the increased use of non-renewable natural resources, an increase of the greenhouse gas emissions, contamination of soil, water, air and the progressive degradation of ecosystems. In the face of such serious threats the global initiatives of all countries are important to limit the results of the excessive consumption. The aim of the article is to present the methods of measurement of the consumption level of natural resources by the societies and the examination of relationships between the level of development of the societies and the use of resources. The popular measure – the ecological footprint – was used as a measurement method for the consumption of the today’s generations in relation to the regenerative possibilities of the natural environment. On the other hand, as the assessment method for the level of development of societies – the Human Development Index (HDI), including three basic areas: the life expectancy, GDP level per capita and education was used. The results of the research indicate that the current trend of the unlimited consumption of the highly developed countries takes place at the expense of the future generations.

The application for a prediction of the coal spontaneous ignition - PREDISAM
DOI 10.1515/mspe-2017-0011
Abstract: The article follows the research of the project number TA01020351 called “The research of possibilities when predicting steam origin and consequent spontaneous ignition of brown coal fuels” which was researched with the support of the Technological Agency in the Czech Republic in 2011-2014 in the connection with a realized technical research. Therefore, it gives a summary information about the evaluation of the risk degree for the origin of spontaneous ignitions of the brown coal. The presented way of evaluation is based on a numeric expression of a value for MHU criteria – the point load of particular indicators is added together with other results gained from this research project. Then, more information is taken from companies running the dumps of brown coal products – both for suppliers (mining companies) and big consumers (power engineering). The complex knowledge about prediction of the origin of the spontaneous ignition enables to make an early response to eliminate a threat of mining fire in open pit mines or on the dumps of coal products. Consequently, it reduces the risk of fire and breakdowns of transportation means DPD, heavy machines and preparation plants. The working injuries are reduced as well – burns by coal in fire or inhalation of gas products from imper-fect combustion.

Prediction of the main engine power of a new container ship at the preliminary design stage
DOI 10.1515/mspe-2017-0014
Abstract: The paper presents mathematical relationships that allow us to forecast the estimated main engine power of new container ships, based on data concerning vessels built in 2005-2015. The presented approximations allow us to estimate the engine power based on the length between perpendiculars and the number of containers the ship will carry. The approximations were developed using simple linear regression and multivariate linear regression analysis. The presented relations have practical application for estimation of container ship engine power needed in preliminary parametric design of the ship. It follows from the above that the use of multiple linear regression to predict the main engine power of a container ship brings more accurate solutions than simple linear regression.

Use of water-fuel mixture in diesel engines at fishing vessels
DOI 10.1515/mspe-2017-0016
Abstract: The paper presents the laboratory test results determining physical parameters of fuel mixture made up of petroleum diesel oil, rapeseed oil methyl esters (up to 20%) and water (up to 2.5%). The obtained parameters prove that adding biocomponents (rapeseed oil methyl esters) and water to fuel does not result in deterioration of their physical and chemical properties and are comparable to base fuel parameters, namely petroleum diesel oil. The mixture was a subject of bench testing with the use of a self-ignition engine by means of precatalytic fuel treatment. The treatment process consisted in fuel – catalytically active material direct contact on the atomizer body. At the comparable operational parameters for the engine, the obtained exhaust gases opacity was lower up to 60% due to the preliminary fuel mixture treat-ment in relation to the factory-made fuel injection system using petroleum diesel oil.

Modeling of surface geometric structure state after intergrated formed milling and burnishing
DOI 10.1515/mspe-2017-0020
Abstract: The article deals with computer-based modeling of burnishing a surface previously milled with a spherical cutter. This method of milling leaves traces, mainly asperities caused by the cutting crossfeed and cutter diameter. The burnishing process – surface plastic treatment – is accompanied by phenomena that take place right in the burnishing ballmilled surface contact zone. The authors present the method for preparing a finite element model and the methodology of tests for the assessment of height parameters of a surface geometrical structure (SGS). In the physical model the workpieces had a cuboidal shape and these dimensions: (width × height × length) 2×1×4.5 mm. As in the process of burnishing a cuboidal workpiece is affected by plastic deformations, the nonlinearities of the milled item were taken into account. The physical model of the process assumed that the burnishing ball would be rolled perpendicularly to milling cutter linear traces. The model tests included the application of three different burnishing forces: 250 N, 500 N and 1000 N. The process modeling featured the contact and pressing of a ball into the workpiece surface till the desired force was attained, then the burnishing ball was rolled along the surface section of 2 mm, and the burnishing force was gradually reduced till the ball left the contact zone. While rolling, the burnishing ball turned by a 23° angle. The cumulative diagrams depict plastic deformations of the modeled surfaces after milling and burnishing with defined force values. The roughness of idealized milled surface was calculated for the physical model under consideration, i.e. in an elementary section between profile peaks spaced at intervals of crossfeed passes, where the milling feed fwm = 0.5 mm. Also, asperi-ties after burnishing were calculated for the same section. The differences of the obtained values fall below 20% of mean values recorded during empirical experiments. The adopted simplification in aftermilling SGS modeling enables substantial acceleration of the computing process. There is a visible reduction of the Ra parameter value for milled and burnished surfaces as the burnishing force rises. The tests determined an optimal burnishing force at a level of 500 N (lowest Ra = 0.24 μm). Further increase in the value of burnishing force turned out not to affect the surface roughness, which is consistent with the results obtained from experimental studies.

An ecosystem perspective on asset management information
DOI 10.1515/mspe-2017-0022
Abstract:Big Data and Internet of Things will increase the amount of data on asset management exceedingly. Data sharing with an increased number of partners in the area of asset management is important when developing business opportunities and new ecosystems. An asset management ecosystem is a complex set of relationships between parties taking part in asset management actions. In this paper, the current barriers and benefits of data sharing are identified based on the results of an interview study. The main benefits are transparency, access to data and reuse of data. New services can be created by taking advantage of data sharing. The main barriers to sharing data are an unclear view of the data sharing process and difficulties to recognize the benefits of data sharing. For overcoming the barriers in data sharing, this paper applies the ecosystem perspective on asset management information. The approach is explained by using the Swedish railway industry as an example.

Stability analysis of radial turning process for superalloys
DOI 10.1515/mspe-2017-0023
Abstract: Stability detection in machining processes is an essential component for the design of efficient machining processes. Automatic methods are able to determine when instability is happening and prevent possible machine failures. In this work a variety of methods are proposed for detecting stability anomalies based on the measured forces in the radial turning process of superalloys. Two different methods are proposed to determine instabilities. Each one is tested on real data obtained in the machining of Waspalloy, Haynes 282 and Inconel 718. Experimental data, in both Conventional and High Pressure Coolant (HPC) environments, are set in four different states depending on materials grain size and Hardness (LGA, LGS, SGA and SGS). Results reveal that PCA method is useful for visualization of the process and detection of anomalies in online processes.

A framework for creating value from fleet data at ecosystem level
DOI 10.1515/mspe-2017-0024
Abstract: As companies have recently gotten more interested in utilizing the increasingly gathered data and realizing the potential of data analysis, the ability to upgrade data into value for business has been recognized as an advantage. Companies gain competitive advantage if they are able to benefit from the fleet data that is produced both in and outside the boundaries of the company. Benefits of fleet management are based on the possibility to have access to the massive amounts of asset data that can then be utilized e.g. to gain cost savings and to develop products and services. The ambition of the companies is to create value from fleet data but this requires that different actors in ecosystem are working together for a common goal – to get the most value out of fleet data for the ecosystem. In order that this could be possible, we need a framework to meet the requirements of the fleet life-cycle data utilization. This means that the different actors in the ecosystem need to understand their role in the fleet data refining process in order to promote the value creation from fleet data. The objective of this paper is to develop a framework for knowledge management in order to create value from fleet data in ecosystems. As a result, we present a conceptual framework which helps companies to develop their asset management practices related to the fleet of assets.

Inteligent performance analysis with a natural language interface
DOI 10.1515/mspe-2017-0025
Abstract: Performance improvement is taken as the primary goal in the asset management. Advanced data analysis is needed to efficiently integrate condition monitoring data into the operation and maintenance. Intelligent stress and condition indices have been developed for control and condition monitoring by combining generalized norms with efficient nonlinear scaling. These nonlinear scaling methodologies can also be used to handle performance measures used for management since management oriented indicators can be presented in the same scale as intelligent condition and stress indices. Performance indicators are responses of the process, machine or system to the stress contributions analyzed from process and condition monitoring data. Scaled values are directly used in intelligent temporal analysis to calculate fluctuations and trends. All these methodologies can be used in prognostics and fatigue prediction. The meanings of the variables are beneficial in extracting expert knowledge and representing information in natural language. The idea of dividing the problems into the variable specific meanings and the directions of interactions provides various improvements for performance monitoring and decision making. The integrated temporal analysis and uncertainty processing facilitates the efficient use of domain expertise. Measurements can be monitored with generalized statistical process control (GSPC) based on the same scaling functions.

Local regularity analysis with wavelet transform in gear tooth failure detection
DOI 10.1515/mspe-2017-0026
Abstract: Diagnosing gear tooth and bearing failures in industrial power transition situations has been studied a lot but challenges still remain. This study aims to look at the problem from a more theoretical perspective. Our goal is to find out if the local regularity i.e. smoothness of the measured signal can be estimated from the vibrations of epicyclic gearboxes and if the regularity can be linked to the meshing events of the gear teeth. Previously it has been shown that the decreasing local regularity of the measured acceleration signals can reveal the inner race faults in slowly rotating bearings. The local regularity is estimated from the modulus maxima ridges of the signal’s wavelet transform. In this study, the measurements come from the epicyclic gearboxes of the Kelukoski water power station (WPS). The very stable rotational speed of the WPS makes it possible to deduce that the gear mesh frequencies of the WPS and a frequency related to the rotation of the turbine blades are the most significant components in the spectra of the estimated local regularity signals

Aggregation of electric current consumption features to extract maintenance KPIs
DOI 10.1515/mspe-2017-0027
Abstract: All electric powered machines offer the possibility of extracting information and calculating Key Performance Indicators (KPIs) from the electric current signal. Depending on the time window, sampling frequency and type of analysis, different indicators from the micro to macro level can be calculated for such aspects as maintenance, production, energy consumption etc. On the micro-level, the indicators are generally used for condition monitoring and diagnostics and are normally based on a short time window and a high sampling frequency. The macro indicators are normally based on a longer time window with a slower sampling frequency and are used as indicators for overall performance, cost or consumption. The indicators can be calculated directly from the current signal but can also be based on a combination of information from the current signal and operational data like rpm, position etc. One or several of those indicators can be used for prediction and prognostics of a machine’s future behavior. This paper uses this technique to calculate indicators for maintenance and energy optimization in electric powered machines and fleets of machines, especially machine tools.

Bottom to top approach for railway KPI generation
DOI 10.1515/mspe-2017-0028
Abstract: Railway maintenance especially on infrastructure produces a vast amount of data. However, having data is not synonymous with having information; rather, data must be processed to extract information. In railway maintenance, the de-velopment of key performance indicators (KPIs) linked to punctuality or capacity can help planned and scheduled maintenance, thus aligning the maintenance department with corporate objectives. There is a need for an improved method to analyse railway data to find the relevant KPIs. The system should support maintainers, answering such questions as what maintenance should be done, where and when. The system should equip the user with the knowledge of the infrastructure's condition and configuration, and the traffic situation so maintenance resources can be targeted to only those areas needing work. The amount of information is vast, so it must be hierarchized and aggregated; users must filter out the useless indicators. Data are fused by compiling several individual indicators into a single index; the resulting composite indicators measure multidimensional concepts which cannot be captured by a single index. The paper describes a method of monitoring a complex entity. In this scenario, a plurality of use indices and weighting values are used to create a composite and aggregated use index from a combination of lower level use indices and weighting values. The resulting composite and aggregated indicators can be a decisionmaking tool for asset managers at different hierarchical levels.

Tapping the value potential of extended asset services - experiences from Finnish companies
DOI 10.1515/mspe-2017-0029
Abstract: Recent developments in information technology and business models enable a wide variety of new services for companies looking for growth in services. Currently, manufacturing companies have been actively developing and providing novel asset based services such as condition monitoring and remote control. However, there is still untapped potential in extending the service delivery to the longterm co-operative development of physical assets over the whole lifecycle. Close collaboration with the end-customer and other stakeholders is needed in order to understand the value generation options. In this paper, we assess some of the asset services manufacturing companies are currently developing. The descriptions of the asset services are based on the results of an industrial workshop in which the companies presented their service development plans. The service propositions are compared with the Total Cost of Ownership and the closed loop life cycle frameworks. Based on the comparison, gaps that indicate potential for extended asset service concepts are recognised. In conclusion, we argue that the manufacturing companies do not recognise the whole potential for asset based services and for optimizing the performance of the end customers’ processes.

Ergonomics contribution in maintainability
DOI 10.1515/mspe-2017-0031
Abstract: The objective of this paper is to describe an ergonomics contribution in maintainability. The economical designs, inputs and training helps to increase the maintainability indicators for industrial devices. This analysis can be helpful, among other cases, to compare systems, to achieve a better design regarding maintainability requirements, to improve this maintainability under specific industrial environment and to foresee maintainability problems due to eventual changes in a device operation conditions. With this purpose, this work first introduces the notion of ergonomics and human fac-tors, maintainability and the implementation of assessment of human postures, including some important postures to perform maintenance activities. A simulation approach is used to identify the critical posture of the maintenance personnel and implements the defined postures with minimal loads on the personnel who use the equipment in a practical scenario. The simulation inputs are given to the designers to improve the workplace/equipment in order to high level of maintainability. Finally, the work concludes summarizing the more significant aspects and suggesting future research.

The aim was achieved thanks to product life cycle assessment (LCA) conducted for stovetop and electric kettles. A literature review was carried out. A research model was worked out on the basis of data available in literature as well as additional experiments. In order to have a better opportunity to compare LCA results with reviewed literature, eco-indicator 99 assessment method was chosen. The functional unit included production, usage and waste disposal of each product (according to from cradle to grave approach) where the main function is boiling 3360 l of water during 4-year period of time. A very detailed life cycle inventory was carried out. The mass of components was determined with accuracy of three decimal places (0.001 g). The majority of environmental impact is caused by electricity or natural gas consumption during usage stage: 92% in case of the electric and kettle and 99% in case of stovetop one. Assembly stage contributed in 7% and 0.8% respectively. Uncertainty and sensitivity analyses took into consideration various waste scenario patterns as well as demand for transport. Environmental impact turned out to be strongly sensitive to a chosen pattern of energy delivery (electricity mix) which determined final comparison results. Basing on LCA results, some improvements of products were suggested. The boiling time optimization was pointed out for electric kettle's efficiency improvement. Obtained results can be used by manufacturers in order to improve their eco-effectiveness. Moreover, conclusions following the research part can influence the future choices of home appliances users.

Biophotonics for biofuel upgradation
DOI 10.1515/mspe-2017-0038
Abstract: Experimental studies have been made to find out Cyanobacterias’ biophotonical response in gaseousfuelation and car-bon dioxide fixation during photo-anaerobic digestion. A new horizontal type photo-bioreactor has been designed by using environment hazard plastic bottles and it works ideally for anoxygenic cyanobacterial growth. Through ‘V3-metagenomics’ of 16S rRNA gene sequencing by paired-end Illumina MiSeq and downstream analysis by QIIME program, we have identified anaerobic cyanobacteria, represent the orders YS2 and Streptophyta. OTUs have been identified by aligning against Greengenes and Silva databases, separately. The flame temperature of the fuel gas is 860°C and the percentcontent of carbon dioxide (CO2) is 17.6%.
Keywords: cyanobacteria, photo-anaerobic digestion, CO2 fixation, gaseous fuels, V3-metagenomics

Information about cost of goods produced and its usefulness for production engineers - a case of SME
DOI 10.1515/mspe-2017-0039
Abstract: The article stresses the consequences of simplifications implemented in the measurement process of goods produced that are of crucial importance to production engineers in SME. The authors show the variety of possibilities that might be used by financial employees together with probable outputs in terms of valuation distortions. Using the case study the authors emphasis the importance of close cooperation of production engineers with finance professionals as out-puts of finance departments consist an important input for decision-making process of production managers. Furthermore, demonstrated deficiencies in terms of methods applicable in financial reporting for measurement of the value of goods produced indicate the need for incorporation more financial and non-financial data in the process of judgments about the final cost of goods produced as simplifications applied in SME distort financial information provided to production engineers.
Keywords: accounting, cost accounting, methods of cost calculations, cost management in SME, production engineering

Reciprocal allocation method in service departments. The case of a production enterprise
DOI 10.1515/mspe-2017-0040
Abstract: The main aim of this article is to indicate the role of reciprocal allocation method in the process of costs calculation. In the environment of nowadays companies, often taking very complex organisational forms, the existence of service departments becomes of great importance. Although, as far as management accounting processes are concerned, which lead to identifying the product cost, the service departments’ costs come out to be of minor importance. This article means to prove that the service departments’ costs and their reliable settlement are a desirable source of information about the products. This work consists of two parts. First of them features theoretical considerations and a critical analysis of subject literature. In the latter part, the service departments’ costs calculation will be presented, basing on recipro-cal services in a production enterprise from chemical industry.
Keywords: management accounting, cost calculation, management of production costs, service department

Operational and strategic controlling tools in microenterprises - case study
DOI 10.1515/mspe-2017-0041
Abstract: Globalisation and increasing requirements of the environment cause the executives and supervisors to search for more and more perfect solutions, allowing them to streamline and improve the effectiveness of company operations. One of such tools, used more and more often, is controlling, the role of which has substantially increased in the recent years. It is already implemented not only in large companies with foreign capital, but also in increasingly smaller entities, which begin to notice the positive effects of the implications of the principles and tools of controlling - both operational and strategic. The purpose of the article is to demonstrate the practical side of controlling tools that can be used for the purposes of operations conducted by microenterprises.
Keywords: strategic controlling, operational controlling, microenterprise
