n个同型部件和k个修理设备的温贮备可修系统的可靠性研究

Study on Reliability of Warm Standby's Repairable System with n Identity Units and k Repair Facilities

在假定部件的工作寿命和贮备寿命以及维修时间都服从指数分布、所有随机变量均相互独立、工作部件的寿命分布与贮备时间无关、故障部件能够修复如新的条件下,对由n个同型部件和k(k≤n)个修理设备组成的温贮备可修系统作了可靠性分析,建立了该类系统的模型,并针对其特殊情形(n=2和k=2)给出了系统可靠性的稳态指标和瞬时指标.

Under the assumptions that the units＇ service life, standby life and maintenance time would follow index distribution, that all random variables would keep mutual independent, that there was no relationship between working parts＇ life distribution and standby time and that defective units would be repaired, a reliability analysis was conducted to study a kind of warm standby repairable system with n identity units and k （k ≤ n） repair facilities. After the system model has been built, the steady-state quantities and the instantaneous quantities of the system were obtained in the light of the given specific situation （n = 2, k = 2）.
