Abstract: To solve the problems of distributed collaboration, information or resources sharing, and knowledge reuse among designers during process of complex product design, a novel method for complex product collaborative design based on cloud service was proposed. The key point of the method was Cloud Service Middleware(CSM). Information, resources and knowledge during design process were described by abundant semantics, which were contained by construction of domain ontology and knowledge base in cloud services. A new service-composition approach was proposed, which integrated event-driven service model and Semantic Service Logic Graphics(S2LG). Firstly, operations such as task decomposition and service publication were completed under event-driven. Then, S2LG was utilized to express logic or sequential relationships among services. Subsequently, service composition was executed to accomplish complex product design. Finally, a case study of the whole design of an aircraft was presented to validate the feasibility and effectiveness of the approach.
