A Method of Determining Quantities of Logistics Infrastructure Based Similarity Degree

Abstract

It is a key topic to determine the number of logistics infrastructures in the process of urban logistics planning which need to consider land use, industrial structure, geographic area, logistics supply and demand, etc. A method of determining quantity of logistics infrastructure based on similarity degree was put forward according to the procedures of logistics infrastructure number determination. With consideration of quantitative and qualitative factors supported by similar system theory and method, the choice of indicators and weight determination were solved by gray relational analytic theory and rough set theory. In addition, a new way to solve similarity degree was applied by using function fitting and diff-area. Finally, a numerical example was given to illustrate the effectiveness and applicability of the method.
