针对具有公共总线性能共享的可修多状态系统，提出了一种瞬时可用度模型。可修MSS由多个多态单元和一个公共总线性能再分配系统组成。系统中的每个单元都有几个性能水平，必须满足其各自的随机需求。如果一个单元具有超过其需求的性能，则该单元可以通过公共总线性能再分配系统将剩余性能真实的传输到其它单元。如果任何一个单元的需求得不到满足，整个系统就会失败。提出了一种基于随机过程方法和泛母函数技术相结合的可修MSS瞬时可用度和平均瞬时性能损失的评估方法。最后给出了两个应用实例。
In this paper, an instantaneous availability model for repairable multi-state system (MSS) with common bus performance sharing is proposed. The repairable MSS consists of some multi-state units and a common bus performance redistribution system. Each unit in the system has several performance levels and must satisfy its individual random demand. A unit can transmit the surplus performance to other units in real time through the common bus performance redistribution system, if it has a performance that exceeds its demand. The entire system fails if the demand of any unit is not satisfied. A new method based on the combination of the stochastic process method and the universal generating function technique is suggested to evaluate the instantaneous availability and the mean instantaneous performance deficiency of the proposed repairable MSS. Two examples are given for applications in the end.
