A service scheduling system in service grid environment

Grids have been established as a new paradigm for delivering information, resources and services to users. OGSA integrates Web service and grid technology to provide grid service that is the abstract of resources. On service grid environment, location transparency of services is a key concept. So, new challenges have arisen in service scheduling. We put forward here a scheduling system to schedule decentralized grid services based on QoS. It cooperates with service container to schedule services by scheduling strategy. Both the architecture and the strategy it used are described.
