摘要
在配送中心选址问题的背景下,从定性和定量两个角度出发分析对比已有的选址评价方法,指出其适用对象。在此基础上,结合指标对比关系的模糊性和指标数值的模糊性,对模糊条件下配送中心选址评价问题进行分类处理:模糊层次分析法确定指标对比关系模糊下的权重,并运用灰色综合评价确定评价对象的优劣性;离差最大化法求得指标数值模糊下的权重,利用改进理想解排序法(TOPSIS)对评价对象按理想程度进行排序。并结合算例说明不同情形下方法的有效性和适用性。
Aiming at the distribution center location,this paper compared the existing location evaluation meth- ods and discussed their applications from the two perspectives of qualitative and quantitative analysis. Combining the fuzziness of the indexes contrast relationship with the fuzziness of the indexes value, it classified and solved the evaluation problems of distribution center location under fuzzy conditions：fuzzy analytic hierarchy process was used to determine the weight of indexes for the fuzzy contrast relationship, and the grey comprehensive evaluation was applied to determine the superiority and inferiority of evaluated objects;the weights of fuzzy indexes was obtained by maximizing deviations, and improved TOPSIS method was adopted to rank the evaluated objects according to the ideal level. Finally, it illustrated the effectiveness and applicability of the evaluation methods under different circumstances through numerical examples.
