基于改进TOPSIS模型的农村物流服务站点选址评价

摘要

在借鉴现有农村物流服务站点选址评价指标的基础上,建立起农村物流服务站点选址评价指标体系,利用改进TOPSIS模型对农村物流服务站点选址进行评价.利用信息熵法和本征向量法求出各指标的客观权重和主观权重,并将客观权重与主观权重进行融合.采用Minkowski距离替换传统TOPSIS法中的Euclid距离,对各农村物流服务站点选址进行了评价.最后分析了该评价模型的可行性和实用性,分析结果表明该评价模型计算简单,决策较为科学,是一种有效的综合评价方法.%In this paper, on the basis of referencing the available evaluation index system for the location allocation of the rural logistics service outlets, we built the corresponding assessment index system which incorporated the improved TOPSIS model to assess the location of the service outlets. Next, we used the information entropy process and the eigenvector process to yield the objective and subjective weight of the indexes and then integrate the two. Then by substituting the Euclid distance in the traditional TOPSIS with the Minkowski distance, we assessed the location of the various outlets. At the end, we analyzed and verified the feasibility and practicality of the model.
