在产品的年需求量依赖于零售商售价的条件下,根据零售商的订货量,供应商给予零售商延期支付的优惠,建立了零售商库存决策模型。从零售商的角度出发,探讨如何制定最优订货周期和最优售价,以实现年总费用最小,并给出寻求模型最优解的算法。最后,通过具体算例,结合灵敏度分析方法,分析了模型中参数变化对最优订货策略的影响。
An inventory model is developed for the case where the time of delay in payments is correlated with order quantity and the demand rate is a function of the retail price.From the perspective of retailer,a mathematical model is developed.The objective is to determine the optimal pricing and the optimal replenishment cycle length to minimize the total cost.We provide theoretical analysis of the optimal solutions and develop a simple method for finding the optimal order policy.Numerical examples are presented to illustrate the sensitivity of the model,and the changes in the total cost of the retailer are discussed with the changes of some parameters.
