Research of dynamic service integration approach oriented to products lifecycle
面向产品生命周期的动态服务集成方法研究*

To meet large manufactory enterprise products lifecycle systems integration complex and frequent change requirements, according to analysis of the lack of existing service oriented architecture (SOA) system integration, this paper proposed a dynamic service integration approach through the adoption of MDA. It was a bi-direction combination of top-down modeling and bottom-up service composition. Domain meta-model was expanded based on UML to describe logic model which abstracted from business process. Integrated systems wrapped as Web service was saved in service metadata repository. Business logic separated from specific integration services, would be translated to integration process instance by reflection mechanism, and deployed to the integration engine automatically. PLM integration platform was established based on the approach. The fact demonstrated the approach can improve the adaptability and agility of integration, increase efficiency and quality, reduce implementation and maintenance costs.
