EXPERT SYSTEM FOR EVALUATING MULTICRITERIA TRANSPORTATION NETWORKS.

An expert system is developed for evaluating transportation network improvement alternatives with multicriteria. The advantages of this system are 1) integrating data, transportation models, and evaluation methods within one framework; 2) applying multicriteria evaluation methods and choice rules for these methods onto various evaluation environments; and 3) providing a friendly man-machine interface. First, a transportation network improvement evaluation problem is specified. Then, an expert system is formulated. The relative data bases, model bases, and knowledge bases are described. Finally, a brief example is used to demonstrate the practicality of the system. The whole program is an integration of LOTUS 123, Turbo PROLOG and C language programs on an IBM personal computer.
