Manufacturing system simulation to evaluate energy productivity (Formulation of relationship between productivity and energy consumption)

Abstract

It is more important to evaluate and reduce energy consumption in designing, operating, and improving systems in industry. Therefore production management methods concurrently considering productivity and energy consumption are needed. Moreover, it is required to maintain a high productivity when energy consumption are reduced. In order to approach the theoretical realization of the production conditions that affect a productivity or energy consumption, we investigate the formulation of the relationship between energy consumption and production throughput, and verify it by using numerical simulation. The dependence of energy consumption per unit of production throughput on lot size, and the relationship between energy consumption per unit of production throughput and throughput are clearly shown.
