Extended economic maintenance scheduling for a batch production system

Abstract

This study develops an extended model to determine the economic production quantity of a batch production system in which a general discrete distribution is used to describe the process failure or process degradation in the production system. The optimal production batch size is determined by minimizing the expected total cost per product during a production cycle, where a loss function is used to measure the quality cost. A numerical example is employed to demonstrate the use of the proposed model. Sensitivity analysis is also performed to determine the various parameter values that affectthe optimal production batch.
