【摘要】 本文对由多状态部件构成的系统的可靠性问题进行了讨论。按状态变量X_i的概率分布定义了它所处的状态及其可靠度,并推出了系统状态可靠度的计算方法。文章的后部分,给出了系统关键变量的概念和具体求关键状态变量的方法,从而可按“关键性”给系统中的元件一个次序,为改善系统的状态及可靠度提供了依据。更多还原

【Abstract】 In this pappr, reliability of system that consists of multistate units is discussed.States and reliability of a state variable X; is defined by its probability distribution.The method of calculation of reliability of system state is obtained. The concept of key variable of system and the concrete calculating method are given in the rearward of this paper. Thus a order of units in system is defined according to "key-property" , which provides basis for improving states and reliability of system.更多还原
