需求替代下易腐品的订货策略和定价策略研究

Pricing and Inventory Control for Deteriorating Products with Demand Substitution

针对蔬菜、水果等这类在存储的过程中随时间的推移会发生大量损耗的易腐品,在激烈的市场竞争中,产品的需求不仅与本身的价格有关,而且与竞争对手产品的价格有关,零售商根据市场需求确定最优定价和订货策略以最大化自身利益,建立库存模型,证明了模型存在唯一最优策略.通过数值实验,分析得到替代程度发生变化对最优策略的影响.

Commodities such as vegetables,fruits,are subject to direct spoilage while kept in store. In this paper,we assume that the retail faces different demand depends on the price and the price of substitute products.We proved existence and uniqueness of optimal strategy.The economic order quantity and the optimal price of the two deteriorating products with priced- driven substitutable demand under the cooperative and competitive situations are derived.The effect of system parameters on the optimal strategy and the optimal profit with substitutable demand are also discussed.
