摘　　要：文中以船舶压载水系统为研究对象,建立压载水调驳不成功为顶事件,运用模糊集合理论建立的故障树,并进行了可靠性计算与分析。继而对压载水系统进行优化,并时优化后的系统进行模糊计算。计算结果表明优化后的压载水系统具有更高的可靠性。In the paper, the ship ballast water system is considered as an object of study, the transportation failure of the ballast water as the top event, a fault tree is established ac- cording to the fuzzy set theory, and the reliability calculation and analysis are carried out. Then the ballast water system is optimized, its reliability is calculated too. The results show that the optimized ballast water system has a higher reliability.
