SBA based integration for the extended enterprise

Extended enterprises will meet many difficult problems especially when it concerns complex products. For example, it´s difficult to share scattered data and control dynamic changing processes. Here we give our solution that uses SBA (Simulated Based Acquisition) thought and ontology to provide complete supports to a long life cycle of complex products. In the grid environment all kinds of resources are composed into a resource tree that is stored in a knowledge base. The interfaces are in the forms of web services that can provide unified visits, and the resources are related to different activities described in a workflow. Everybody concerned in this process can get his/her suitable information from a resource tree that is provided through out the process, operate the resources and get advices from this system at each activity of it. By now a part of prototype system has been implemented.
