A mission-oriented shipboard spare parts allowance method using reliability simulation

A simulation method for calculating the quantity of spare parts carried in the ship which performs a mission is proposed. This method evaluates the impact of the related equipment failure on the overall mission reliability of ship after the increase of each spare part, predicts the requirements of the spare parts, and optimizes the shipboard spare parts allowance scheme with the purpose of optimizing the availability or mission reliability of the ship during the mission. And this method improves the execution efficiency of the simulation optimization method. Particularly, it is suitable for the large-scale system as ship with such a large number of spare parts and complex task execution process.
