摘　　要：基于模糊集合理论定义失效的结构可靠性分析方法，应用降低方差技巧的ＭｏｎｔｅＣａｒｌｏ方法，对１１５０００ＤＷＴ油轮的总纵强度进行了分析；结果表明该方法是合理的，模糊集合理论在船舶结构可靠性分析中具有应用前景．A method for structural reliability analysis based on fuzzy definition of failure is presented. The reliability analysis of the longitudinal strength of a 115000 DWT tanker has been carried out by using Monte-Carlo method with conditional expectation Variance Reduction Technique and antithetic variate Variance Reduction Technique.
