Abstract: By collecting the use stage quality dates of a certain ship power system, the Pareto diagram method is used to analyze the quality dates, so the main failure phenomenon that impact the power system are gained and the relevant reasons are analyzed. Then the Repairable system reliability analysis method is employed to calculate the mission reliability of the power system. Finally, the mission reliability under typical mission profile of the power system is calculated. The findings can provide data support for the maintenance of the power equipment.
