【摘要】 在多个服务台可服务同台故障机器且维修率可变的条件下,通过矩阵分析的方法得到稳态概率的矩阵方程。然后给出稳态概率数值算例,建立费用模型,讨论了维修率总费用的影响,并得到了使总费用最小的维修率。更多还原

【Abstract】 On the condition that multi-service machines served the same breakdown machine and maintenance rate was variable,the matrix equations of steady-state probabilities were obtained by the matrix analytical method with numerical examples. Furthermore,this paper developed a cost model and analyzed the influence of maintenance rate on the total cost. The maintenance rate of minimum total cost was got.更多还原
