Study on fuzzy matter-element model based on grey relevancy analysis in comprehensive evaluation of logistics center location

Logistics center location is a key step of logistics system optimization, so it is important to select a proper method to assess it. First, the index system for location evaluation of logistics center is constructed by analyzing influencing factors of logistics center location. Then, the fuzzy matter-element model based on grey relevancy analysis is built in view of the fuzziness and incompatibility of evaluation index in evaluation of logistics center location, and the model is used to choose the best scheme. Finally, the example indicates that the model is simple and convenient. It can effectively reduce subjective effect in the course of evaluation, and it can overall and objectively appraise the schemes of the logistics center location.
