两种产品可以互相替换的Newsboy存贮问题

A two-item newsboy inventory problem with substitutability

生活中2种产品的互相替换是十分平常的,因此讨论具有相同使用属性的多种可相互替换物品的存贮问题是必要的,文章讨论2种产品可以相互替换的Newsboy存贮问题。假设2种产品在使用过程中,一种短缺而另一种剩余,则相互发生替换;通过建立2种产品可以相互替换的Newsboy存贮问题的总费用数用模型,然后结合应用实例给出最优数值解及参数的灵敏度分析。

It is very common in practical life that two kinds of products substitute for each other, so it is meaningful to discuss the invertory problem in which multiple items can substitute for each other. In this paper, a two-item newsboy inventory problem with substitutability is discussed. Suppose the two kinds of products are consumed, when one is in storage and the other is in shortage, then the substitution of one for the other occurs. A mathematical model of this newsboy invertory problem considering the total cost is developed, application examples are presented, and the optimal numerical solution and sensitivity analysis of substitutive parameters are given.
