The Design and Maintenance for the Model Base of Intelligent Vehicle Dispatch System
智能运输调度系统模型库构造与管理

Based on current studies and prospects, a classification scheme is proposed for the models of vehicle routing and scheduling problems(VRSP) from the point of view of system design. The representations of knowledge of model classes are given. This paper reveals profoundly the relations among model classes of VRSP. The father class, son class, polynomial derivation class, similar class, polynomial derivation hyperson and equivalent class are discussed respectively. The union, intersection and supplement of model classes are investigated. Finally, a frame design is presented for the model base and its management system of VRSP. The ideas and methods proposed in this paper are meaningful for general intelligent management system design.
