云制造为企业间的合作提供一种全新的网络化应用新模式.为实现高效智能地从已发布的大规模候选云服务中选择满足企业合作需求的云服务,在对云服务进行规范化的语义描述和本体建模基础上,提出一种分阶段的云服务智能选择算法.首先利用服务类别语义相似度和状态信息对候选云服务进行初步选择,接着根据候选云服务和请求云服务输入输出功能的语义包含关系以及服务功能属性对候选云服务进行再选择,最后对候选云服务的非功能属性进行选择,从而得到最优的云服务.实例和实验仿真表明了本文算法的有效性和可行性.
Cloud Manufacturing provides a new model of network application for cooperation among enterprises.In order to efficiently and intelligently select the cloud services from the large-scale candidate cloud services that have been released and meet the needs of enterprise cooperation, cloud services are standardized semantics Description and ontology modeling, a staged cloud service intelligent selection algorithm is proposed.Firstly, the candidate cloud service is preliminarily selected based on the semantic similarity and state information of service category, and then based on the candidate cloud service and request cloud service input and output function Semantic inclusion relation and service function attribute to select the candidate cloud service, and finally choose the non-functional attribute of the candidate cloud service to get the optimal cloud service.Examples and experimental simulations show the effectiveness and feasibility of the proposed algorithm .
