| Outline of Final Research Achievements |
It applies some results of maintenance models to an armour block facility.
The armour block facility is subject to waves which occur at a stochastic process. As a result, facility's resistance deteriorates with elapsed time. The deterioration process is assumed as a stochastic process. The facility is broken by a strong shock when a load of the shock exceeds the resistance level. The broken facility is maintained immediately as corrective maintenance. In order to reduce a total maintenance cost, we carry out preventive maintenance. As a criterion for maintenance decision making, it adopts a total expected maintenance cost over an infinite time horizon. A necessary condition to minimize the criterion is discussed. Finally, some numerical examples are given.
