摘要
进一步研究服务设备可修的机器修理模型,在引入服务设备的"广义忙期"的基础上,提出了一种新的分析方法——分解法.应用该方法,重新讨论了服务设备的两个主要可靠性指标,即在时刻t服务设备失效的概率和(0,t]内失效的平均次数,而且进一步得到服务设备的这两个主要可靠性指标的重要的分解关系式.
In this paper the model of service machines with repairable equipment is further studied. By introducing the generalized busy period of the service equipment, a new analyzsis approach--the decomposition method is provided, and by using the method two main reliability indices--the probability of that the service equipment fails at time t and the average number of failure occurring during the time interval （0, t ]are discussed again. Some important relations of the two indices are given.
