摘要:
同种产品以多种价格同时销售(多种价格策略)是零售商常用的折扣策略,为了找到多种价格策略下零售商实现期望利润最大化的订购量,对经典报童模型进行拓展,分别从无订购量约束和订购量约束两方面进行研究和讨论.在多种价格对应消费者需求不确定情况下建立一个新的报童模型,使用拉格朗日乘子法求解订购量约束问题,并设计近似最优总订购量的求解算法.数值分析结果表明:多种价格策略优于单一价格策略,订购量约束对零售商多种价格策略的选择会产生影响;在有订购量约束情况下,零售商的多种价格策略还会受到价格折扣系数、需求差异性的影响.

Abstract:
It is a popular discount strategy for retailers to sell the same product at multiple prices simultaneously(multiple-price strategy). In order to determine the order quantity of the retailer such that the expected profit is maximized, the classical newsboy problem is extended, and a new newsboy model is established wherein multiple prices correspond to uncertain consumer demand. Two aspects of with and without order quantity constraint are discussed respectively. The Lagrangian multiplier method is applied to solve the order quantity constraint problem, and an algorithm for solving the approximate optimal total order quantity is designed. Numerical results show that the multiple-price strategy is better than a single price strategy, and order quantity constraint has an impact on the choice of the retailers' multiple-price strategy. The retailer's multiple-price strategy is also affected by the price discount coefficient and the difference in demand in the case of order quantity constraint.
Key words:  newsboy problem  optimal ordering strategy  Lagrangian multiplier method  multiple-price  order quantity constraint
