Abstract

We propose an approach to making train schedules by simulation and a train traffic model suitable for simulation. This model is developed based on a Col- oured Petri Net (CP-net), an enhancement of Petri Net which is known as a graphic tool applicable to the analysis of concurrent, asynchronous and dis- tributed systems. Some of the advantages of our CP-net based train traffic model are that it is a universal model suitable for various kinds of software which deal with train schedules; simulation on this model always produces a feasible train schedule and it is helpful in making the software more compact, robust, re-usable, efficient and enhanced. In this paper, we introduce the model together with an outline of a train schedule planning system develop
