Workflow-Based,Service Oriented Distance-Distributed Collaboration Simulation System

Workflow,being one of the key techniques in distributed-collaboration application,is analyzed from the service-oriented angle,and the concept of workflow grid resource is put forward.The workflow model is defined as the grid resource, and described according to the grid resource definition.The workflow-collaboration is implemented from the grid base level.Based on the prototype of workflow model and SOA architecture,the distributed-collaboration architecture is built up in the grid system.The service oriented and workflow-based distributedcollaboration simulation system is implemented based on the principle of design given above.
