摘要: 多状态n中连续取k系统是二值状态n中连续取k系统扩展到多状态的一般模型.多状态n中连续取k系统可靠性的求解问题是可靠性工程中一个热点和难点.当元件及系统具有多状态时分析了系统的可靠性与元件的可靠性之间的关系.对于系统处于不同状态时具有不同的可靠性结构的情形,提出了计算多状态n中连续取k坏系统可靠性的递归算法.实例对比说明了该方法的正确性和可用性.该方法不仅适用于递减或递增多状态系统,而且对系统及部件所处的状态数目的大小不加要求,为进一步研究复杂多状态系统奠定了基础.

Abstract: Multi-state consecutive-k-out-of-n system is the model that is generalized form two-state consecutive-k-out-of-n system. The reliability estimation of multi-state consecutive-k-out-of-n system is a hot and difficult spot in the reliability engineering field. When both the system and its components have different states: from complete failure up to perfect functioning and performance rate is associated with each component state, the reliability of the system was analyzed based on the reliability of components. The multi-state consecutive-k-out-of-n:F system may have different structures at different system levels. A new recursive algorithm for obtaining the system state distribution of multi-state consecutive-k-out-of-n:F system including the decreasing multi-state F system, the increasing multi-state F system, and other F systems was proposed. An instance was provided to illustrate the accuracy and availability of the method in the reliability estimation through comparison with the enumerating method. This algorithm is more effective for systems with many components. Moreover, it establishes foundation to the research on the complex multi-state system.
