Economic and ecological costs of heating and optimum thickness of the thermal insulation

Abstract: This article presents the method of the assessment of the ecological costs of heating, which was modelled after the method for assessment of the economical costs of heating. Thanks to that, it is possible to analytically describe, in a similar fashion to the economic one, the ecological net present value of the thermal insulation investment, and to assess the optimum thickness of the thermal insulation both from the economic and ecological perspective. Different cases occurring in Polish conditions were also examined. Different variants were also analyzed: construction material of the building wall, type of a heat source, type of the thermal insulation material. The diversity of the climate zones in Poland was also taken into consideration. For all examined variants, the assessed optimal thickness of the thermal insulation layer from the ecological perspective was much bigger than from the economic perspective. Implementation of the greater thicknesses of the thermal insulation than the optimal from the economic perspective is beneficial. In this way, with the small decrease of the economical benefits, the greater ecological benefits from the thermal insulation investment are achieved.

Principles for modeling the action of crisis in the crisis - applying simulation of processes

Abstract: This article provides an overview of possible methods and tools for modeling activities and simulating processes. These are: decision tables, decomposition tree and decision tree, decision diagrams and process maps; BPMN notation. Based on the literature and their own experience using the tools and simulation methods described in the article, it was found that process maps are useful tools for modeling from the point of view of the sequence of events that occur in their course. Therefore, the BPMN notation is intended to be used for reasons of transparency, indication of the individual actions, processes and decisions of the various sources and information resources, and to ensure that the records are organized; and the assumptions of separation of sequences of activities and communication - information flows.

Analysis of the share and importance of quality control methods used to detect non-conformance of aluminum profiles

Abstract: This paper presents the results of the analysis of the contribution and importance of specific quality control methods used to detect the non-conformance of the aluminum profiles produced by the pressing process. Specific quality control methods such as measurement, testing, verification, visual inspection, numerical control and alternative control have been analyzed. The quality control processes used were identified. The Pareto-Lorenz diagram was used to identify the critical non-conformity of the examined product over a period of one year. The relationship between the presence of quality control methods in detecting nonconformities and the inconsistencies detected by the quality control methods examined has been analyzed. An analysis of the risks associated with nonconformities detected by the tested quality control methods was also conducted based on the FMEA indicators (priority numbers). The control method that most often involved detecting non-conformance of aluminum profiles and detecting the most incompatibilities is the visual inspection. This control is also responsible for detecting inconsistencies with the greatest risk and importance for the customer, and hence the need for managers to increase their effectiveness.

The use of CFD for assessment methane hazard

Abstract: One of the commonly present gas hazard in hard coal mines methane hazard. The most endangered region by this hazard, during ventilation of longwall in „U from boundaries” system is the crossing with ventilation roadway (so called “upper corner of longwall”). Accumulation of methane in this place results from its release from goaf. Therefore, in order to decrease methane concentration in this region, auxiliary ventilation devices are used. In the paper results of numerical studies of distribution of methane concentration in hazardous zone (upper corner of longwall) are presented. The obtained results clearly show that numerical methods, combined with the results of tests in real conditions can be successfully used for the analysis of variants of processes related to ventilation of underground mining, and also in the analysis of emergency states.

Circular economy a way to sustainable development

Abstract: The increase in amount of produced waste in European countries and the problem with its management were one of the reasons of a document titled ‘Towards a circular economy: A zero waste programme for Europe’ (2014). The closed-loop waste management also known as circular economy is intended to be a solution of waste problem and a way to achieve the sustainable development. In order to achieve the goal, an implementation of a lot of formalized and nonformalized environmental management instruments is required. It is necessary not only at the enterprise level, but also more effective involvement of the state and society is needed. In the article, the main aims of the closed-loop economy and its three pillars are presented. The improvement in communication and information transmission are also highlighted. In case of the pillar of the society bigger involvement and the increase of effectiveness of waste segregation is required.
