在可靠性分析中,除了常见的随机不确定信息,还普遍存在着模糊不确定信息,因此在传统可靠性的基础上基于模糊理论提出了一种综合处理随机不确定信息与模糊不确定信息的可靠度计算方法。并在应力—强度干涉模型的基础上得出了未被大家重视的可靠度分布曲线,获得了能同时处理概率密度函数与隶属函数的可靠度计算模型,并探索了此模型与模糊可靠性、经典可靠性之间的内在联系。研究结果表明:在随机性与模糊性并存的情况下,此可靠性度量模型能够较好的处理随机信息与模糊信息,所得结果有很高的准确性,并且能够动态的反映可靠度的计算机理。
In the reliability analysis, in addition to the common random uncertain information, the fuzzy uncertain information also exists unceasingly. Based on the traditional reliability, based on the fuzzy theory, a new method to deal with the random uncertain information and the fuzzy uncertain information Reliability calculation method. Based on the stress - strength interference model, the reliability distribution curve that has not been taken seriously by people is obtained. The reliability calculation model which can deal with the probability density function and membership function simultaneously is obtained. The model is also discussed with fuzzy reliability, The intrinsic link between classic reliability. The results show that the reliability measure model can deal with random and fuzzy information well under the coexistence of randomness and ambiguity. The reliability of the reliability measurement model is highly accurate and can be used to dynamically reflect the reliability of the calculation .
