AN IMPROVED POLICY ITERATION ALGORITHM FOR SEMI-MARKOV MAINTENANCE PROBLEMS Academic Article uri icon

abstract

  • This paper uses a general maintenance problem and a new policy iteration algorithm to solve most semiMarkovian maintenance models. This algorithm decomposes the maintenance process into a deteriorating process and a sequence of replacement and repair actions so that the number of states involved in the decision process is less than the state space of the unmaintained process. Consequently, the number of equations to be solved at every iteration step can be substantially reduced. The improved policy iteration algorithm and the conventional policy iteration algorithm are compared in a set of randomly generated semi-Markov maintenance problems. 1992 Taylor & Francis Group, LLC.
