Abstract:

To achieve the target of combination and reusing for distributed resources during complex product collaborative design, a collaborative reusing structure based on services was built up. For realizing interoperation among heterogeneous collaborative services, a share ontology was constructed for design domain and a private ontology was established for tool resources. The invoking performance depends on ontology conversion. Collaborative service planning was divided into issue, search and planning phases. Service planning algorithm was proposed to get feasible combination schemes. At last, an ontology description of atom service was listed. Based on a serial of calculation services, an aero-engine compressor design instance was used to validate the service planning algorithm.

Key words: collaborative service, service composition, service planning;interoperation

摘要：

为了解决分布式设计资源在复杂产品协同工作中的组合重用问题,建立了设计资源的协同服务体系结构,以协同服务封装可被重用的设计资源。面向不同领域建立共享本体,面向领域内设计资源建立私有本体,实现异构资源间功能与数据的互操作。划分了协同服务规划的不同阶段,给出了服务规划方案的生成算法,以获得服务组合的可行规划方案集合。最后以航空发动机中压气机设计为例,给出了原子服务的本体描述实例,并验证了协同服务规划算法的有效性。
