基于语义的虚拟企业制造服务建模技术研究

Semantic-based virtual enterprise manufacturing services modeling technology

为了实现协同制造环境下虚拟企业制造服务的自动发现、合成和执行,提出了一种基于语义的制造服务模型,从制造服务的资源构成视图、基本信息视图、功能视图、服务质量视图、访问视图和状态视图对制造服务进行了建模,并采用形式化语言对制造服务模型加以规范化的描述。在此基础上,采用扩展的Web服务本体描述语言对制造服务进行了建模实现。最后,基于网状中心城市区域网络化制造专业平台,开发了面向协同制造的虚拟企业制造服务管理原型系统,并验证了该原型系统的可行性。

To realize the automatic discovery, composition and execution of virtual enterprise manufacturing services in the context of collaborative manufacturing, a manufacturing services concept model based on semantics was presented, which consisted of resource constitution view, basic information view, function view, quality of service view, accessing view and status view, and canonical presentation was given to describe the manufacturing services by using formal language. Based on the construction of manufacturing service concept mode/and describing the concept model in formal language, the manufacturing services model was realized by extended Web Ontology Language for Service （OWL-S）. Finally, a prototype system of virtual enterprise manufacturing services management in the context of collaborative manufacturing was realized based on the Reticular Central City Regional Networked Manufacturing Platform （RCCRNMP）, and its feasibility was verified.
