基于随机变质时间的易腐商品定价模型研究

易腐商品的变质时间通常无法确定，销售易腐商品的价格随商品寿命发生变化.由于易腐商品的社会必需性以及数量大、容易变质等特点，销售商必然关注易腐商品在经营周期内的最优定价问题.研究了一类不确定易腐时间商品的定价模型，定量地分析了随机变质时间、商品量、顾客需求与最优定价的关系，确定了最优定价策略.所建立的模型允许在变质开始后，根据现有商品量以及剩余经营周期时间长度做一次价格调整.并通过仿真实例验证了有效性.

Study on pricing model of perishable goods in random deteriorating time

Deteriorating time for perishable goods is unascertainable,and the prices of the goods change with the life of the goods.Due to the characteristics of the social necessity,large quantity and easy deterioration of the perishables,retailers must care about optimal pricing in their marketing cycle.A pricing model for a type of perishables with uncertain deteriorating time is discussed,and the relationships among their random (deteriorating) time,quantity of goods,needs of buyers and optimal price are analyzed.An optimal pricing strategy is determined.In this model,retailers can adjust their price once according to their remaining (quantity) of goods and the length of remain marketing cycle.Finally,an example is simulated and the (efficiency) of the method is testified.
