本文提出了一种具有公共节点性能共享的多状态n中取：G系统，其中考虑了n中取k：G结构，并首次将系统状态划分为多个层次。这样的系统由一条公共总线和多个状态单元组成，其中每个单元具有多个性能水平以满足其各自的随机需求。如果一个单元具有剩余的性能，则可以通过公共总线将性能剩余传输到正在经历性能缺陷的其他单元。根据满足需求的单元数量，将系统状态划分为多个层次。提出了一种基于通用母函数(UGF)技术和随机过程方法的系统可靠性评估算法。最后，给出了分析和数值算例，说明了该方法的应用。
In this paper, a multi-statek-out-of-n:Gsystem with common bus performance sharing is proposed, in whichk-out-of-n:Gstructure is considered, and the system state is divided into multiple levels for the first time. Such a system consists of a common bus andnmulti-state units, where each unit has several performance levels to satisfy its individual random demands. If one unit has surplus performance, the performance surplus can be transmitted to other units which are experiencing performance deficiency via the common bus. The state of the system is divided into multiple levels according to the number of the units whose demands are satisfied. An algorithm based on the universal generating function (UGF) technique and the stochastic process method is proposed to evaluate the system reliability. Analytical and numerical examples are presented for demonstrating the application of the proposed method finally.
