Expected Maintenance Actions for Imperfect Production Processes Using a Markovian Approach

In practice, most of the production systems are not perfect in that defectives are often produced. Even though the maintenance of such imperfect production systems has been studied, the maintenance strategies obtained by a Markovian approach are limited. In this paper, expected maintenance actions for imperfect production processes are developed using a Markovian approach. An integrated maintenance action model has been developed in order to determine the required preventive maintenance, inspection, and minimal repair for each state. The expected total cost has been obtained that covers the cost of the production process with the cost of maintenance.
