摘要
给出了带有两类不同部件的温贮备系统模型。其中1型部件不可修,但有优先使用权;2型部件可修;部件的工作及修复寿命均服从指数分布,系统的状态为一时齐的马氏链。利用柯尔莫哥洛夫前进方程求出了系统的可用度及可靠度。数值计算结果表明该方法的可行性。
Redundancy or standby is a technique that has been widely applied to improve system reliability and availability in system design. A warm standby system with two categories of components is studied. One category of components is type 1 and the other type 2. Type 2 is repairable but type 1 isn＇ t. Type 1 components have priority of operation over type 2. The operating lifetime and repair lifetime of all components follow exponential distributions. Thus, the system states are homogenous Markov chain. Two important reliability indexes of reliability and availability are obtained according to the kehnogonov-feller forward equation. Finally, a numerical example is used to show the proposed approach.
