SOA Technology Research And Application In Aircraft Collaborative Design

Aircraft design is a trans-disciplinary process. On one hand, the fields involved in have differentknowledge scope and programming habits. The application systems developed by each field areusually based on the different operation environments, using different development platforms,because of lacking of unified programming model. Therefore,“information island" phenomenoncomes into being, which makes data sharing and information interaction among various disciplinesimpossible. Aircraft design, on the other hand, is a gradually iterative process. The plan shall adjustconstantly during the process. Each round of designing is expensive and disturbing.To solve the problems mentioned-above, the main content of this thesis is as following: we applythe idea of SOA to designing an Aircraft Collaborative Design System. Directed against the dataintegration platform we present a Global Uniform Model Generation Algorithm, which transforms theheterogeneous relationship data into a unified global pattern. It has solved the heterogeneous dataintegration problems. We adopt service data objects to encapsulate the generated global unifiedpattern as service, which is convenient to add, delete, change and check. Then we further analyze ESB.On the basis of integration layer in Service-Oriented Architecture Solution Stack, the DynamicAdaptative Trusted Service Mechanism and the Trusted Service Select Algorithm are presented. Bycomparing service discovery success rates between static service discovery and dynamic servicediscovery, the experimental results show that the algorithm presented in our paper has a obviousadvantage. We introduce the implementation of each layer in ACDS.In the last part of this thesis, we have a test on the Aircraft Collaborative Design System andanalyze the system performance which has met the requirements of the design.
