Various strategies can be applied to improve reliability at certain costs, including equipment redundancy, product storage, and maintenance, which gives rise to the problem of optimally allocating the reliability improvement costs among the strategies and balancing them against the potential loss due to unavailabilities. Motivated by the reliability concerns of air separation units, we use Markov Decision Process to model the stochastic dynamic decision making process of condition-based maintenance assuming bathtub shaped failure rate curves of single units, which is then embedded into a non-convex MINLP (DMP) that considers the trade-off among all the decisions. An initial attempt to directly solve the MINLP (DMP) for a mid-sized problem with several global solvers reveals severe computational difficulties. In response, we propose a custom two-phase algorithm that greatly reduces the required computation effort. The algorithm also shows consistent performance over randomly generated problems around the original example of 4 processing stages and problems of larger sizes.
