Cloud design service platform and key technology based on semantic Web

Aiming at the characteristics of the design resource such as distributed,heterogeneous and service-oriented under cloud design environment and the requirement of small and medium manufacturing enterprises for external design resource and design capabilities,a semantic Web based cloud design service platform was designed which could realize design resource integration sharing and support small and medium enterprises' resource integration and industrial cooperation.The hierarchical architecture and the operation mechanism of cloud platform were given.The construction methods of resource virtualization and cloud resource pool based on Web service and ontology was discussed.Resource dynamic capabilities and customer demand expression model oriented to product information model was built.Semantic reasoning based resource retrieval and matching algorithm was studied.Through Flex and Java,a cloud platform prototype system was developed.The feasibility and effectiveness of the proposed platform was verified by using UG software to design a landing gear cylinder.
