零售商部分延期支付下的动态库存和融资策略

Study on Dynamic Inventory and Financing Strategy with Partial Delay in Payment by Retailer Allowed

在供应商允许零售商部分延期支付的条件下,讨论了风险中性的零售商周期性地订购一种产品以满足不确定性需求的随机动态库存决策问题,建立了优化补货和融资策略的库存模型,目的是最大化零售商计划期末的期望资金水平。零售商订货时可以使用自有资金和/或贷款资金,订货后如果有剩余资金,可通过无风险投资获得无风险收益。分析了给定初始资金和库存时的最优策略,并给出了数值实验。

In this paper, upon the premise that the supplier allows the partial delay in payment of the retailer, we discussed the stochastic dynamic inventory decision-making problem of a risk-neutral retailer that made cyclic ordering of a product to meet the uncertain demand for it, built the inventory model that optimized its replenishment and financing strategies so as to maximize the expected fund level of the retailer at the end of a term, and at the end, presented a numerical example to analyze the optimal initial investment and the optimal inventory level.
