OPTIMIZATION OF THE THRESHOLD FOR PREVENTIVE MAINTENANCE ACTIONS IN A CONDITION-BASED MAINTENANCE PROGRAM USING A DYNAMIC PROGRAMMING APPROACH

The last step of a condition based maintenance (CBM) program is maintenance decision-making. Sufficient and efficient decision support is crucial to the decision of maintenance personnel on taking maintenance actions. This decision making should be undertaken according to certain criteria such as risk, cost, reliability and avail¬ability. This paper considered a dynamic programming model to optimize the threshold for preventive maintenance ac¬tions in a condition-based maintenance program. The basis of this modeling is the average cost of maintenance actions, failures and exchanges. In this paper, we im¬proved the memory of the deterioration of the model with coefficient (a). We compute the optimal point to exchange the machine and plotted the time value of Money to simplify.
