| Abstract: | 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. |
