摘要
本文讨论一种库存、维修综合模型,其中需求、维修时间和滞后期均为随机现象.以马尔科夫过程为出发点并引用排队论中的某些结果,对系统的稳态行为作出定量分析,得到各种系统评估,包括帐面及实际库存的分布和均值,并建立目标函数.
An overall inventory and repair model with stochastic demands, time lagging and repair time is discussed, in which the repair capacity R has to be chosen simultaneously with the order quantity Q and the maximum inventory level S. Using the Markovian process and certain results from the queuing theory, the steady state system behaviour is studied analytically and various system performance assessments have been obtained, iccluding inventory position and on hand inventory. An objective function for system optimization is developed.
