A Multi-agent Framework for Grid Service Workflow Embedded with Coloured Petri Nets

The dynamics of Grid calls for flexible and adaptive workflow systems. This paper integrates Web Services and intelligent resource allocation mechanism (through Agent technologies) to Grid Services Workflow System embedded with Coloured Petri Nets (CPNs). The cooperation of Agents and CPNs enhances the adaptability of the framework. We discuss how Web Services can be located and the services provided by them can be invoked. We also discuss how the Agents and Web Services can co-exist to create highly flexible and dynamic Grid Services Workflow System. Finally this paper shows how our framework can be used to achieve adaptability from process, resource and task perspectives through an example of airline ticket service system.
