This project investigates the optimal maintenance decision-making problem for deteriorating systems operating in a variable environment with selectable operations. Since there are strong dynamic interactions among a deteriorating system, its surrounding environment, and the operation being executed, this project formulates the optimal decision-making problem for this system as a non-stationary Markov decision process. The structural properties of the resulting optimal expected cost function are examined, and the optimal maintenance policy is found to be given by a control limit policy under certain conditions. Based on the obtained control limit structure, an algorithm is provided for searching the optimal maintenance policy for a deterioration system under a varying environment. Such maintenance policy enhances the dynamic decision-making process for deteriorating systems operating in a variable environment, and supports the implementation of a system-specific maintenance plan.
