Abstract
There are two kinds of method in ship maintenance. One is the corrective maintenance and the other is the preventive maintenance. For these maintenances, recently the stochastic techniques are widely used to keep ships in good conditions and in these maintenances it is most important to seek the maximum availability and the optimal maintenance period minimizing a given cost function. Thus, this paper suggests a method to decide the optimal policy of ship's maintenances by using Dynamic Programming and the effectiveness of the method is verified through several examples in which failure rates and maintenance data of ship's machineries and parts are given.
