Research on Dynamic Grid Workflow Model of ITS
智能公交系统中动态网格工作流模型研究

Aiming at the problem that it is hard to scheduling vehicles in ITS,the characteristic and requirement of the workflow model for real-time vehicles scheduling in Grid environments which cross lots of domains and systems was presented.A meta-model of workflow was proposed for ITS vehicles scheduling.It utilizes Petri Net-based flexible workflow model technique and top down layered decomposition approach to create the workflow model.And then a dynamic modifying strategy was proposed in order to suit the ideas...
