The Research Of The Automatic Estimation Of Traffic Connection About City Logistics Center

Nowadays, as the third Profit headspring, modern logistics is getting more and more important ,the aim of which is satisfying the requirement of the clients and reducing the cost at the same time. Distribution center, as the product of the society and specialty in logistics domain, plays an important role in logistics functions.This article makes research on the automatic estimation of traffic connection about city logistics center. Firstly, it summarizes the methods and achievements of domestic and foreign scholars on the ability of logistics center's transportation, discovered that most of them are center on the issue of selecting position or vehicle when they study on the transpotation of city logistics center. In order to definite the objectives of the study, it simply introduces the concept, classification and function of logistics center. Then it analyses the existing state and problems about the traffic connection of logistics center, especially the connection of highway, waterage and railway. Through the introduction of the theoretical basis, it advances the fundamental he automatic estimation of traffic connection about city logistics center, including the method, basis, criteria, index and parameter of estimation. And introduces the two common types of estimation technology that is Analytic Hierarchy Process, and Generalized Indicator Functions.At last, through the active fuzzy database technology and fuzzy implements the automatic estimation of traffic connection about city logistics center, analyses the existing database information systems of logistics center including the function modules, conceptual structure and logical structure .It builds relation fuzzy data model and fuzzy implements the automatic estimation of traffic connection.
