带有可追加订购和季节性销售的报童问题

Can be ordered with an additional and seasonal sales newsboy problem

商品作为使用价值存在一定的时间限制,尤其是季节性的单周期销售商品,如果在一定时间内第一次订购量不足,应进行追加订购,在一定时期内没有卖掉的商品应进行降价销售,最后没有销售掉的商品,则按残价处理,使零售商获得最大的期望利润。从追加订购和季节性销售两个方面考虑,求解一个最佳订购量,使新模型的收益达到最大,通过研究,我们发现新模型比经典报童模型、或一次订购二次降价销售的报童模型、或可追加订购的报童模型的收益均有较大的提高,同时还分析了模型的灵敏度及服务水平。

There is a certain value of commodities as of the time constraints, especially in seasonal merchandise sales of single - cycle, if a certain period of time less than the first order, should be an additional order, in a certain period of time not to sell the commodity prices should be carried out sales, if the final products do not sell out, according to the residual price so that retailers get the most profit expectations. In this paper, an additional order from two aspects of sales and seasonal consid- erations, solving one of the best order quantity, so that the new model to maximize revenue, through research, we found that the new model compared with the classical newsboy model, or a sale of the Second Order newsboy model , or can be ordered additional, much more better.
