Manufacturing System Simulation for Evaluation of Productivity and Energy Consumption

Abstract

Industries need to evaluate productivity and energy consumption concurrently when designing and improving manufacturing systems. Manufacturing system simulation to evaluate productivity was often used. However, manufacturing system simulation to evaluate productivity and energy consumption concurrently was not proposed. The purpose of our research is to establish manufacturing system simulation for productivity and energy consumption. In this paper, first, requirements for manufacturing system simulation are analyzed. Second, functions considering analyzed requirements are proposed. The functions are a state transition model for facilities, a simulation system, and an evaluation system. Third, a manufacturing system simulation environment which is implemented the functions is also proposed. Finally, case studies for a small scale machining line and a middle scale semiconductor manufacturing line are carried out to confirm the efficiency of our proposed simulation.
