Abstract
This paper aims at developing a model for the planned maintenance program and long-run average cost. Markov process decision approach in its discrete version used to model the problem. Penalty cost model due to shifting paradigm as approach applied for textile boiler maintenance program by taking three components of the boiler. Whereas, a three-step policy iteration algorithm, initialization, value determination and policy improvement, for numerical experimentation based on component current age and the schedule maintenance time for the planned maintenance program considered. Relative values (RV), which are not only immediate value from an action taken from planned activity but also are guaranteed values that would be resulted from the accomplishment of the maintenance action specified on the maintenance policy proposed. More importantly, unless a trade-off is made, RVs instead are costs in the long run and this is what the average cost-policy compromise and the policy iteration assures while, as time gets advance the deterioration rate of the components expected to increase, shifting forward will bear an extra cost is the underlying. With this proposed approach, for validation purpose, relative values (RV), based on the two shifting strategies, Forward (FW) and Backward (BW) shifting compared with that of on-schedule (OSC) maintenance, stationary policy based on the long-run average cost obtained to be 2053Birr for the specified case.
