利用位相结构矩阵分析理论,研究了具有相型寿命G一PH型CIMS生产线的随机结构和性态。首先证明在平稳状态下这一复杂可修生产线等价于一个闭排队网络1,然后给出生产线稳态时在首级加工时刻和在任意时刻的两类生产指标和可靠性... 利用位相结构矩阵分析理论,研究了具有相型寿命G一PH型CIMS生产线的随机结构和性态。首先证明在平稳状态下这一复杂可修生产线等价于一个闭排队网络1,然后给出生产线稳态时在首级加工时刻和在任意时刻的两类生产指标和可靠性指标。 展开更多

The stationary probability vectors of a second order Markov chain on the(n-1)-dimensional standard simplex are considered.In 2015,Li and Zhang gave a characterization of the second order Markov chain such that every vector in the simplex is a stationary vector.A modification of the characterization is presented in the paper.Some sufficient conditions are derived for any facet of the simplex such that every vector of the facet is a stationary vector. 展开更多
