摘要: 基于需求和返回是相互独立泊松过程的假设,将(R,Q)库存策略控制下的逆向物流库存系统建模成马尔可夫链,并依此对逆向物流库存系统的稳态表现进行分析,得到了系统的总成本期望值函数.论述了最优控制参数的优化方法,并通过数值算例考察了产品返回过程对系统最优总成本的影响.

Abstract: Based on the assumption that demand and return are independent Poisson processes, the inventory position was modeled into a Markov chain. By solving this Markov chain, this paper derived the limiting performance of the inventory system and hence the system expected total cost per unit time. A heuristic approach was developed to determine the upper and lower bounds for the optimal control parameters. The numerical examples show that the reuse of the return items is economical.
