摘要
本文以两级可修备件库存系统为研究对象,采用马尔可夫到达过程(MAP)描述备件需求规律,考虑有限维修设施的情况,假设故障件维修时间、备件运输时间以及采购时间均服从phase-type(PH)分布,建立了一种描述能力更强、解析计算性更好的(S-1,S)库存优化模型,并推导出系统缺货量分布函数;然后通过算例演示了模型的优化效果,验证了模型的正确性和适用性。
This paper investigates a two-echolon inventory system with （S-1, S） policy that consists of several same repairable items and single repair facility, and assumes that the item de- mand occur according to a markovian arrival process （MAP）, the repair time, ship time and procurement time follow the general distribution which is represented by phase-type （PH） dis- tribution. Then a inventory optimization model with better description ability and analytical per- formance is given, and the probability distribution of backorder is obtained. Finally, a numeri- cal example was given to illustrate the effectiveness of the model.
