摘要
文中在零售商对易逝品进行技术投入的同时,还考虑了库存衰减率.以企业利润最大化为目标,建立动态定价模型,寻求易逝品销售的最优策略.首先利用哈密尔顿函数建立零售商的利润函数,然后利用最优控制理论得出不同参数下零售商的最优策略,接着将此定价策略代入忽略库存衰减率的利润模型,跟原模型所得利润进行比较,得出忽略库存衰减率会对零售商造成极大利润损失的结论,最后利用灵敏度分析研究不同参数下零售商忽略库存衰减率时利润损失的变化.
We formulate a dynamic pricing model for perishable foods,in which the retailer′s technical investment in perishable goods and the inventory decay rate are considered. First,we establish the retailer′s profit function based on the Hamilton function. Then,we search for the optimal strategy under different parameters while maximizing the total profit of the retailers. Next,we substitute the pricing strategy into the profit model that ignores the inventory decay rate. Finally, we come to the conclusion that ignoring the inventory decay rate can cause significant profit loss to the retailer. At the same time,we make use of sensitivity analysis to study the change of the loss of profit.
