چکیده
Comprehensive transportation network layout planning should pay more attention to the coordination and connection of various means of transport. In the course of layout planning, it is very necessary to consider all the views of experts from different domains. Based on analyzing the procedure and the characteristics of the comprehensive transportation network layout planning, this paper firstly points out the necessity of setting up an intelligent group decision support system. For achieving the functions and design requirements, then the logical structure of the system is proposed, and the composition of database, model base, method base, knowledge base and the functions design of each subsystem are described and analyzed in detail. Finally the group inference decision mechanism and processing flow based on fuzzy evaluation method is illustrated. The system has practical application value in providing decision support for specific transportation network layout planning.
