Improved maintenance strategy for a parallel leased machines system

The aim of this paper is to develop an improved maintenance strategy for a manufacturing system composed by several identical parallel leased machines using Center-of-Gravity approach. We present at first the optimal production plan of the studied system found by minimizing its total cost of leasing, setup, inventory and work times. Then, according to the obtained production plan, we determine the maintenance strategy for each machine. Once found, these plans are used to find the configuration of the new improved maintenance strategy by combining numerous maintenance actions in a single and unique one according to Center-of-Gravity approach.
