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 system. With this technique, each object in the simulation model has the attributes, operations, and structures of its counterpart in the real world. This will resolve the complexity in the knowledge representation of the rapid transit system. To simulate continuous train movements under discrete train movement orders, expert system based event objects are implemented. Normally, simulation is used to aid the desing of the rapid transit system. As the object-oriented techique provides reusability, extendibility and high efficiency for future development, simulation cost and developmental cost for future designs are reduced tremendously.
