在预付款策略中,引入熵成本来构建零售商的库存模型,并结合数值分析探讨零售商的最优订货策略.研究发现,考虑熵成本的预付款模型中,随着供应商要求的预付期的增加,零售商的最优订货周期和最优订货批量下降,单位产品流动产生的熵成本上升,单位时间总成本下降.随着利息率的增加,最优订货周期和最优订货批量下降,单位产品流动产生的熵成本在上升,单位时间总成本上升.订货批量越大,单位产品流动产生的熵成本越小.含有熵成本的模型中的最优订货量稳健性,高于不考虑熵成本的库存模型中的,并且受利息收益率和预付款提前期的影响较小.
In the advance payment strategy, the entropy cost is introduced to construct the retailer’s inventory model, and the retailer’s optimal ordering strategy is discussed through numerical analysis.It is found that with the prepayment model considering the entropy cost, , The optimal ordering cycle and the optimal order quantity of retailers decrease, the entropy cost of unit product flow increases, and the total cost per unit time decreases.With the increase of interest rate, the optimal order cycle and the optimal order quantity decline, The entropy cost of unit product flow is rising, and the total cost per unit time is increasing.When the order quantity is larger, the entropy cost of product flow per unit is smaller.The optimal ordering quantity in the model with entropy cost is more robust than that without considering entropy The cost of the inventory model, and by the interest rate and prepayment advances less impact.
