Abstract

The constant maintenance interval performed by ROK Navy ships has the advantage of convenient maintenance planning. In the past study, the failure rate of the ship continued to change with the life of the ship. Planned maintenance performed at regular intervals may not be appropriate to maintain the varying amount of failure of ships. Probability-based maintenance considers the changing amount of ship failure. Although the effect of probability-based maintenance was derived from previous studies, it was studied based on a single ship. Therefore, in this study, the effect of applying probability-based maintenance to multiple ships was confirmed as in reality. When maintenance was performed according to probability, the maintenance time overlapped and queuing occurred. The system dynamics simulation was performed considering the advantages of applying probability-based maintenance and the disadvantages due to queuing at the same time.
