Mission Reliability Simulation Method of Ship Propulsive System

Abstract

For the problems such as data acquisition and process description ability on the reliability research of multistage complex repairable system in traditional statistical evaluation model based on statistic and interpretation calculation model based on reliability block diagram. An object-oriented hierarchical and modular simulation method was used to decompose the task process into several sub-processes according to the task target. And then through the modeling of internal running rules of sub-processes, a mission reliability simulation model of a complex repairable ship propulsive system with multitask process and multiuse state was established, and the effect of gradual failures were also integrate into the simulation of the task process. Finally, a certain type of marine steam power system was taken as an example to verify the feasibility of this method.
