有限期内考虑货币时间价值的两级信用期易逝品库存模型

Study on Currency Time Value Considered Two-level Trade Credit Inventory Model for Deteriorating Items within Finite Period

在有限期内考虑货币时间价值的情况下,研究了需求依赖于库存、且供应商与零售商之间、零售商与顾客之间存在两级信用期的易变质产品的库存策略,并建立了相应的库存模型,证明模型存在最优解,并给出了该模型的数值算例。

Gonsidering the time value of currency, we studied the inventory strategy for deteriorating items whose demand was dependent on the inventory and with two-level trade credit between the supplier and the retailer, and between the retailer and the customer within a finite period, established the corresponding inventory model, proved the existence of an optimal solution for the model and presented a numerical example.
