| 摘 要： | 考虑具有独立维修规则的两不同型部件冷储备系统的可靠性.在一个部件的维修分布为Erlang分布,另外3个分布均为一般连续型分布的假定下,利用补充变量法和拉普拉斯变换工具,得到了系统主要可靠性指标的拉普拉斯变换表达式,如:系统的首次失效时间分布,系统的可用度,修理工空闲的概率和(0,t]时间内系统的平均故障次数等.

| Abstract: | In this paper,the reliability of a two-dissimilarunit cold standby system with separated repair rule is discussed.In the system,the repair distribution of only one unit is assumed to be Erlang and the other three distributions to be general continuous.The Laplace transform expressions of some primary reliability indexes of the system are obtained by using the supplementary variable method and the tool of the Laplace transform,such as the distribution of the first failure time of the system,the availability of the system,the idleness probability for the repair crew and the expected number of failures of the system during(0,t],etc. |
