一个带有回收费用和短缺费用的ATO系统

An ATO System with Salvage Cost and Backorder Cost

在本文中,我们对Hale,Pyke和Rudi提出的模型进行了改进。他们考虑的是一个有两个产品且每个产品都由两个元件构成,每个产品有一个元件不可替代。低价产品中另一个元件短缺时．可用另一产品中的一个高价元件代替。但是这个模型只考虑了回收费用而不包括短缺费用。本文则建立了一个包括回收费用和短缺费用的新ATO模型,在保证商家收益最大的条件下得到了这四个元件存贮的上下界。

In the article, we verify the model that is built by Hale, Pyke and Rudi. But they just consider a system that has two products, and each product has two components. When the component of cheap product is out of stock, it can be substituted by the component of another expensive product. Only the salvage cost is included in this model, and the backorder cost is out of consideration. Here we build a new ATO system with the salvage cost and the backorder cost. On the condition of assuring producer＇ s maximum profit, we get the holding property and bounds of four components.
