| 摘 要： | 通常模糊数据可依据专家有限经验给出,如何利用这些有限的模糊数据获得较为理想的可靠性分析结果是一个亟待解决的问题。文中将Bootstrap方法引入到模糊可靠性分析中,讨论如何从有限的专家的经验数据中重复抽样,充分利用这些经验数据进行模糊可靠性分析,得到可靠性指标的置信区间,算例验证了此方法的可行性。

| Abstract: | Fuzzy data are usually obtained according to the experience of limited experts,therefore, how to use these limited fuzzy dada to obtain rational results in fuzzy reliability analysis is a problem that should be solved. In this paper, the Bootstrap method is introduced to resampling from the limited experiential data so that the fuzzy reliability can be analyzed based on the experiential data. By using the Bootstrap method,the confidence intervals of fuzzy reliability indexes can also be obtained. An example is given to demonstrate the feasibility of the method. |
