摘要: 为了研究不同维修效果下多状态可修系统的可靠性模型,考虑修后恢复修前状态、维修效果较差和维修效果好3种不同维修效果,假设系统工作状态可以划分为完好和一般两类,系统工作时间和维修时间服从连续Phase-type分布,建立系统状态马尔可夫转换的无穷小生成元矩阵,求得各状态稳态概率向量,给出了系统稳态可用度、稳态故障率的解析表达式。通过算例验证了该模型的有效性和适用性。

Abstract: Three repair effects, namely repairing some system and making it as same as the original, imperfect and perfect, are proposed to research the reliability model of multi-state repairable systems with the different repair effects. The operating state is divided into two classes: good and general; the operation and repair times of system are assumed to submit to continuous phase-type distribution. An infinitesimal generator matrix for the Markov transfer among system states is established, and the stationary probability vector is achieved. The proposed model provides the analytic expressions of the stationary availability and failure rate. Finally, the numerical examples are given to illustrate the effectiveness and applicability of model.
