An integrated approach for production scheduling and maintenance of multi-component system

In this paper, an integrated approach for production scheduling and maintenance is proposed for a multi-component system. The model in this paper is based on the selective maintenance policy. The objective is to obtain a minimum cost solution with availability, allowable maintenance time as constraints. The optimization procedure using the proposed integrated approach results into maintenance decision in terms of maintenance actions namely, repair, replace or do-nothing for the system components along with the optimal production schedule on the machines. A simulated annealing algorithm is used for getting the near optimal solution. A numerical example is presented to demonstrate the application of the integrated approach.
