A Study on Lot-Size Dependence of Energy Consumption per Unit of Production Throughput Considering Buffer Capacity

Abstract

A quantitative evaluation and reduction of consumption energy on all production activities and a factory management with focus on consumption energy are necessary for industries. Previous studies were conducted on the formulation of lot-size dependence of energy consumption per unit of production. However, the effect of interprocess buffer capacity was not clarified in the formulation. In this study, the lot-size dependence of the energy consumption per unit of production with consideration of the buffer capacity is formulated. Furthermore, a simulation of a semiconductor production line is performed to verify the validity of the formulation.
