基于不完全信息的混联系统的可靠度

Reliability of compound systems under incomplete information

目的求解两类混联系统的可靠度。方法当仅知系统部件失效分布的部分信息时,利用不精确概率理论对系统建模,分析其可靠性。结果获得了两类混联系统可靠度上下界的表达式。结论所提出的模型及其分析方法是传统方法的推广,它的使用范围广,更切合实际。

Aim In order to seek the reliabilities of two compound systems. Methods The model is put forth and the reliabilities of compound systems are analyzed on the basis of the imprecise probability theory when only some imprecise imformation of failure distribution of component is known. Results The upper and the lower bounds of compound systems are obtained. Conclusion The method is an extension of the conventional method and is more practical in reality.
