| 摘 要： | 基于L.A.Zadeh的语言概率（即模糊概率）场中模糊概率运算的思想，研究工程结构／系统的第二类模糊可靠度的具体算法。用模糊集扩展原因给出第二类模糊可靠性问题中模糊概率的计算公式，并给出和证明了满足概率运算封闭性的模糊集分解定理。研究了当工程结构／系统的抗力和荷载效应具有模糊概率时工程结构／系统模糊可靠度的的计算方法。分析表明：工程结构／系统的第二类模糊可靠度的计算可转化为求解一系列最优化问题，算例结果表明了所给算法的合理性。

| Abstract: | Based on L.A.Zadeh's idea of fuzzy probability operation in his language probability which space is fuzzy probability,the concrete algorithm of the second kind fuzzy reliability of engineering structure/system is researched.The calculating equation of the fuzzy probabiliy of the second kind fuzzy reliability is given out by using the extension principle for fuzzy sets.The fuzzy set decompose theorem,which satesfies the closed probability operation,is given out and proved.The method calculating fuzzy reliability of that structure/system is studied,where the resistance and load effect of the structure/system have probability.The analysis indicates that the calculation of the second kind fuzzy reliability for a structure/system can be transformed into a series of solving optimum programming.The result of the example indicates the rationality of above algorithm. |
