Abstract

In today's competitive market, all manufacturers attempt to improve their maintenance policy in order to decrease the cost of failure and increase the quality of products, but most of these attempts do not consider the role of humans involved in a manufacturing system. Human resources are the main factor in manufacturing that has an undeniable effect on products quality, machines reliability, safety and maintenance policy. In this paper we propose a nonlinear mathematical model that optimizes the maintenance policy considering the humans fatigue to investigate its effects on reliability and associated Costs in manufacturing system.
That is to say, the model is a reliability based maintenance optimization that aims to maintain the reliability of machines and their human resources in a proper predetermined interval. The performance of the proposed model was examined by some instances and the obtained results indicated this model can provide effectiveness maintenance policy for manufacturing systems.
