Industries have been becoming more important to evaluate and reduce energy consumption when designing, operating, and improving manufacturing systems. In our past research, manufacturing system simulation to evaluate productivity and energy consumption concurrently has been proposed and developed for designing, operating, and improving the manufacturing systems. We also proposed a formulation for relationships between lot size and energy consumption per unit of production throughput. However, on our proposed formation, we did not consider the breakdown states in each facilities. In this paper, we propose a formulation concerning relationships between lot size and energy consumption per unit of production throughput considering breakdown states. This proposed formulation is an approach for 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 taking into account breakdown states, and verify it by using our developed simulation. Concerning the investigation, a middle-scale semiconductor manufacturing line which consist of three facilities, a solder printing facility, an IC mounting facility, and a solder reflow facility is simulated. Through the investigation, the relation between lot size and energy consumption per production throughput, production throughput are being understood.
