摘要
研究制造网格中基于语义的服务表示,在此基础上提出了一种基于语义的逆向递归服务自动组合方法。该方法面向用户目标搜索制造网格服务,生成备选服务组合,然后采用TQCSEKL七项指标评价备选组合的综合服务质量,从中选出最优组合。服务组合的结果存储到共享仓库,支持基于目标匹配的查找和局部调度重用。实现了一个基于语义的企业制造网格系统,验证了方法的有效性。
Studies semantic based representation of Manufacturing Grid（MG） service, and then proposes a backward recursive approach for automatic service composition. By this approach,MG services are searched to generate alternative compositions, and then the quality of service（QoS）-a combination of TQCSEKL is employed to evaluate and select optimal ones from these compositions. Result compositions are loaded into a shared warehouse, which supports rediscovery, and reuse of the composed services. A semantic-based enterprise MG is implemented and the efficiency of the approach is verified.
