Application of Fuzzy Extension Analytic Hierarchy Process in Location Selection of Logistics Center

Abstract

This paper use fuzzy extension analytic method to solve the problem of location selection of logistics center. First, establish an evaluation system. There are three first-level indicators at the criterion level, which are social benefits, economic benefits, and infrastructure, and nine second-level indicators at the sub-criteria level. The extension analytic method is used to compare all the factors corresponding to the layer to the first factor and use the number of extension intervals to compare them in pairs, so as to construct a judgment matrix for the extension interval and find the weight vector. Further hierarchical ranking is performed. Secondly, the fuzzy comprehensive evaluation method is used to determine the factor set and evaluation set of influencing factors, and the evaluation matrix is established. The primary element is used to determine the evaluation model. First-level evaluation is performed on each logistics center to obtain a second-level evaluation matrix. The model comprehensively evaluates the two-level evaluation matrix, and then ranks the evaluation levels of each which introduces extension theory, considers human ambiguity, uses interval numbers instead of specific numbers to construct a judgment matrix. The example proves that the ranking is more practical and provides a theoretical basis for site selection.
