Reliability is the most important qualitative properties of products and industrial electronic systems. Today, industrial electronic systems need to produce products with maximum reliability. In every industry, when a system fails, it becomes harmful in various aspects such as economic, human and political; therefore, accurate estimation of system reliability is very important. Previous methods to calculate system reliability assumed that a large number of components failures are statistically independent. Considering such a hypothesis makes it possible to calculate probability and mathematical computation, but it does not provide perfect system reliability. This paper presents a simple and new technique for reliability analysis by considering unequal reliability and non-identical distribution of correlated components for k -out-of- n and coherent systems. The efficiency of our proposed method is demonstrated by computing the reliability of Bridge system. The results show that the function of existing components correlation has a major impact, and that ignoring it has a significant effect on system safety.

基于非相同关联元件的故障类型通用电子系统可靠性模型及灵敏度分析

可靠性是产品和工业电子系统最重要的质量特性。今天，工业电子系统需要生产具有最高可靠性的产品。在每一个行业，当一个系统出现故障时，它就会在经济、人力和政治等各个方面产生危害；因此，准确估计系统可靠性非常重要。以前计算系统可靠性的方法假设大量组件故障在统计上是独立的。考虑这样的假设使得计算概率和数学计算成为可能，但它不能提供完美的系统可靠性。本文通过考虑 k-out-of-n 和相干系统的不等可靠性和相关分量的非相同分布，提出了一种简单而新颖的可靠性分析技术。通过计算桥梁系统的可靠性证明了我们提出的方法的效率。结果表明，现有组件的功能相关性具有重大影响，忽略它对系统安全性有显着影响。
