Simulation modelling of environmental and economic aspects in manufacturing systems

Abstract

The presented manuscript deals with the new simulation modelling approach for the environmental and economic aspects evaluation in a sustainably justified manufacturing system. First, the research problem of simulation modelling methods for the evaluation of environmental and economic aspects of manufacturing systems is presented and defined. Then a new data-driven simulation modelling approach for environmental and economic aspects of manufacturing systems is presented. The newly proposed block diagram is used from a theoretical and applied point of view. Two major environmental and economic aspects are optimized in terms of machine scrap rate and electrical energy consumption. Promising theoretical results from the proposed block diagram are transferred into a practical application. The numerical and graphical simulation results obtained prove the high relevance of the optimization approaches used. The obtained optimization results of the simulation modelling show a reduction of the electrical energy consumption by an average of 11.6% compared to the initial manufacturing system stage. The importance of proper optimization of the machine scrap rate was demonstrated, using the proposed simulation modelling approach. The optimization results show a high degree suitability of the simulation model approach in the order of the evaluation environmental, economic and other social aspects of sustainable manufacturing systems.
