基于混合整数规划的配送中心选址研究

目前关于选址问题研究有很多,基于混合整数规划的选址问题研究也有一些,但是还存在一些问题。其中一个是,在目前的多源供应模型中(即多工厂),只考虑了单位产品的运输费用,都没有考虑到工厂到配送中心和配送中心到客户路线开启的固定成本投入,即一条线路上不管运多运少其单位价格都一样,这显然是不合理的。因此本文在原来混合整数规划模型的基础上考虑以上线路开启的固定成本投入,建立了新的模型,并且进行实例求解。

Study on Location of Distribution Centers Based on IBM ILOG CPLEX and Mixed Integer Programming

Currently,there are many researches on location,also has some location researches based on mixed integer programming,but it still has some problems.One of the problems is that many existence multi-supplier models didn’t consider the fixed cost about opening the transportation line,but just consider the transportation cost of every unit.This is clearly unreasonable.So based on the existence mixed integer programming model of location,this paper considers the cost mentioned above,creates a new model,and solves the problem in a concrete examples.
