云制造服务资源多层次匹配算法研究

Research on Multi-Layer Matching Algorithm of Cloud Manufacturing Service Resource

针对云制造服务资源匹配的问题,在综合考虑云制造服务资源需求的基础上,提出了包括基本信息匹配、功能匹配、约束匹配和综合匹配四个层次的云制造服务资源多层次匹配算法,对匹配模型和匹配算法进行了研究,并详细阐述了每个层次的匹配内容,并给出了每个层次的相似度函数,再用相似度计算定量地描述云制造资源需求和云制造服务资源间的匹配程度,使服务资源匹配更趋于准确和智能。最后,用实例验证了该匹配算法的有效性和可行性。

To deal with cloud manufacturing services resource matching problem, considering the impact of cloud manufacturing resource requirements, a multi-layer matching algorithm of cloud manufacturing which includes basic information matching, function matching, constraint matching and integrated matching four layers is proposed, and matching model and matching algorithm is studied and content and similarity function of each layer is elaborated, matching degree between cloud manufacturing resource requirements and the cloud manufacturing resources is estimated by calculating the quantitative similarity, and the service resources matching is made to be more precise. An example is given to verify the effectiveness and feasibility of the matching algorithm
