Abstract: To efficiently search the service which meets the user requirements and realizes the exact matching with requesting service from published cloud services, an intelligent service searching and matching method for cloud manufacturing service based on formal description of cloud manufacturing services was proposed. This method included two parts： according to types and status information, a preliminary set of candidate services was obtained by filtering the published services rapidly; through functional and non-functional property matching between published and requested services, the service with maximum matching degree for cloud manufacturing from candidate services collection was selected. Case analysis and comparative study demonstrated that the proposed cloud service matching approach was feasible and effective. It could not only realize efficient service searching and matching, but also have significance for promoting the development and application of cloud manufacturing.

摘要： 为高效地从已发布的制造云服务中搜索到满足要求的服务，实现与请求服务的准确匹配，在对制造云服务进行形式化描述的基础上，提出一种智能化的制造云服务搜索与匹配方法。该方法主要包括两部分：根据服务的类型和状态信息，快速过滤发布端服务，得到初步的候选服务集合；通过对请求端与发布端服务进行功能属性、非功能属性匹配，从候选服务集合中筛选出具有最高匹配度的制造云服务。实例分析和比较研究说明，相对于已有的服务匹配方法，该方法可行有效，不仅能实现制造云服务的高效搜索与准确匹配，而且对推动云制造技术的发展与应用具有重要意义。
