经典Newsboy模型是在购买价格不变的情形下去确定最优进货批量.然而,对于一些具有特定的消费时间的商品(如中秋节的月饼等),生产厂家为了更好地安排生产,通常提供提前购买价格折扣.这样确定何时进货、进多少货的问题对经销商来说就显得非常重要.本文研究了该问题,并建立了带有提前购买价格折扣的易逝品的一个库存模型,同时也给出了应用实例与参数的灵敏度分析.

The classical random inventory models are usually ones in which the optimal order lot-size is determined under the situation with the fixed purchasing price. However, for some merchandize with the special consumed time, such as the moon-cake for Middle-Autumn Festival, etc., the manufacture for these items provide a price discount for early purchase in order to reduce inventory level. Thus, it is very important for the vendor to determine when to order and how much to order. In this paper, this problem is discussed. A new inventory model is developed for deteriorating items with the price discount for early purchase. Numerical example and sensitivity analyses of parameters are also shown.
