Abstract

Preventive maintenance (PM) widely exists in the operation process of the production system, which affects the transient and steady-state performance analysis of the production system. Production system modeling is the process of revealing the relationship between component characteristics and performance measures. In this paper, a new modeling method for serial production systems with exponential machines considering periodic PM is proposed. By using this modeling method, the transient and steady-state analysis of the production system can be performed. This model can be solved without using the traditional iterative procedure. The numerical case studies demonstrate the accuracy of this method compared to the simulation results. According to the analysis results in this paper, PM can significantly improve the production rate of the production system, so it should be taken into account when modeling and optimizing the production system.
