建立了由一个仓库和一个加工车间组成的库存一加工系统模型,该模型具有随机的需求过程和随机的供货时间。在假设允许缺货,订货带有批量折扣,并采用(s,S)库存策略的条件下,用排队论得到了该系统的无穷小生成元,给出了系统的费用函数,并对库存策略进行了优化分析。
An inventory-production system with stochastic demand process and stochastic replenishment composed of one workshop and one warehouse is discussed, Assuming that the stock-out is allowed, the ordering has a batch discount and the (s, S) stock strategy is used, The infinitesimal generator of the Markov process system is obtained by the means of queuing theory, The system expense function is provided and the optimized analysis to the stock strategy is made.
