基于两级信用支付的两货栈订购策略研究

Research on Duo-warehouse Ordering Strategy Based on Two-grade Trade Credit

已有的两级信用支付库存模型忽略了零售商自有库存是有限的,而事实上,为了获得供应商提供的更长的信用支付期,零售商会增加其订购量,进而零售商的决策会受到自有库存容量的限制。构建了基于两级信用支付、自有库存容量有限条件下的零售商最优订购策略模型。研究表明,针对不同参数组合,零售商为了获得年平均费用最小值,需要在是否享用供应商提供的更长信用支付期与是否租用库存之间进行权衡。

The existing inventory models of two-grade trade credit mostly ignore the limitation of the retailer's own inventory. In fact, in order to obtain a longer credit payment period from the supplier, the retailer would increase its order volume. Therefore, the retailer's decision-making would be restricted by its own inventory capacity. In this paper, we built the retailer's optimal ordering strategy model based on two-grade trade credit and limited own inventory capacity. It is shown that for different combinations of parameters, in order to minimize the annual average cost, the retailer needs to reach a balance between whether to enjoy the longer credit payment period from the supplier or to rent additional inventory.
