Outline of Final Research Achievements

In the industrial world, it is important to reduce energy consumption while maintaining a certain level of productivity. Research is still in progress on a preliminary evaluation method that grasps the amount of energy consumed on the production line and quantifies and evaluates the energy consumption per unit product based on the amount of production per unit of time. In addition, production control methods to optimize energy consumption per unit product based on production variation factors such as lot size have not been studied. Therefore, this study proposes a modeling and simulation method to evaluate energy consumption per unit product on a production line and verifies its effectiveness. In addition, we used the proposed simulation method to analyze and evaluate trends in energy consumption per unit product due to production fluctuation factors such as lot size, and based on the results, we proposed a mathematical method and verified its validity.
