电子商务环境下物流配送中心选址模型与评价方法

考虑电子商务环境下的物流配送特殊性,将物流配送中心选址模型从变动费用和时间约束的条件进行修改,建立适用于电子商务环境下的物流配送中心选址模型。选址模型是NP问题,故应用启发式算法进行求解。由于电子商务环境下的物流配送中心选址涉及到多方面的因素,是一项复杂的系统工程,建立选址模型时,很难将选址中的所有影响因素考虑周全;即使把这些因素考虑全面,也很难量化形成模型中的约束条件。因此,在进行电子商务环境下物流配送中心选址时,还应咨询和参考各相关专家的意见和建议,进行定性的选择。为此,提出了定量化的启发式算法与定性化的综合评价法相结合来确定电子商务环境下配送中心选址的方法。

Research on Logistics Distribution Center Location model and Evaluation Under Electronic Commerce

This study establishes the logistics distribution center location model under electronics commerce and modifies alternative expenses and time-restricting conditions of logistics distribution center location model according to the specific feature of model under electronics commerce.Because location model is a NP question,the result is solved through heuristic arithmetic.It's difficult to consider all the factors during the course of establishing the logistics distribution center location model.And it is also difficult to quantify the restricting condition in model.Therefore,it is very necessary to ask for the experts' opinion and advice and do some qualitative decisions.On the basis of this hypothesis,this study makes certain the logistics distribution center location under electronic commerce using the combined method of quantitative heuristic arithmetic with qualitative analytic hierarchy process.
