Service-oriented integration of industrial simulation codes

The service-oriented integration approach is presented to integrate many geographically and logically distributed, heterogeneous industrial simulation codes. The hierarchy is decomposed into four layers: the infrastructure layer, concrete web service layer, business service layer and application layer. The paper presents an approach to encapsulate industrial simulation codes into services following Web Service Resource Framework (WSRF) specification which can make them offer their services and functionality in a standard web service environment. To hide the complexity, changeability and the technical details (such as web services´ WSDL address) of concrete web services for business users, these concrete web services are virtualized as business services. Three kinds of virtualization patterns are presented in the paper. Engineers can compose these business services in a high level to complete virtual product development. At last, we give a use case to validate our method and put forward the future work.
