A Review on Joint Optimization of Maintenance with Production Planning and Spare Part Inventory Management

Abstract

In maintenance system, the increasing complexity of the manufacturing system and the joint optimization of maintenance is catching the attention of researches. Therefore, the aim of the paper is to review the literatures on joint optimization of maintenance with other interrelated functions in the manufacturing system. The classification is made based on the type of decision variables, which are production planning (production scheduling, lot sizing and buffer) and spare part inventory management. The relationships and dependencies are explain in the discussion to show the significance of the integrated model. Most studies considered two functions in their integrated model, which is either maintenance policy with production planning or maintenance policy with spare part management. It can be observe that research on optimization of more than two functions is still new and yet to be explore. Moreover, most researches focused at the decision-making phase without extensive discussion in various functions that might involve. The objective function which is the cost is also presented in the paper. The objective function is categorized into two criteria: maintenance related cost and also inventory and spare part related cost.
