DEVELOPMENT OF AN OBJECT-ORIENTED ENVIRONMENT FOR MODERN MASS RAPID-TRANSIT SYSTEM-DESIGN AND SIMULATION

This paper presents object-oriented simulation of the rapid transit sy stem. With the object-oriented technique, each object in the simulatio n model has the attributes, operations, and structures of its counterp art in the real world. This will resolve the complexity in the knowled ge representation of the rapid transit system. To simulate continuous train movements under discrete train movement orders, expert system ba sed event objects are implemented. Normally, simulation is used to aid the design of the rapid transit system. As the object-oriented techni que provides reusability, extendibility, and high efficiency for futur e development, simulation cost and developmental cost for future desig ns are reduced tremendously.
