Economic Production Quantity Model with Energy Consideration


Nowadays, energy saving is one of the main concerns of companies. Therefore, different studies have developed and integrated methods to measure the energy consumption of machine tools. In this paper, an integrated economic production quantity (EPQ) model that considers energy consumption is analyzed. The concept of specific energy consumption (SEC) is used to evaluate the energy consumption during the production time of the machine. Three types of SEC, depending on the production rate, were considered. By minimizing the total cost, the status of the machine in the non-production phase, the optimal production rate, the optimal cycle time, and the influence of these different methods of measuring energy consumption are defined. The results of the study show that the difference in using the SEC -types model does not affect the state selection of the machine during the non-production phase but can change the optimal solutions of the overall system. From the manager's point of view, the choice of different models to represent the energy consumption of the machine leads to different optimal decisions. Numerical analysis are performed, and results are discussed.
