| Abstract: | Along with the application and popularity of transportation information grid system, users become more and more, original configuration can’t meet actual demand. In this paper we create timed colored Petri net process model for transportation information service on demand, which is one of the main services provided by the system. Through simulating increasing users and the amount of procedures for service on demand, we analysis the change of request response time, and provide good reference for capacity expansion of system configuration. |
