云制造环境下基于功能需求的资源发现方法

Resource discovery approach based on functional requirements in cloud manufacturing environment

云制造环境中存在大量功能相同或相似的资源,使得用户很难获得符合需求的资源。针对这个关键问题,对云制造环境下基于功能需求的资源发现进行了研究,提出了一种云制造资源发现框架。首先对云制造资源进行形式化描述,并分别计算语义相似性,然后进行加权相似度计算,最后采用聚类技术,从功能相似角度对资源进行聚类预处理,从而降低资源查找空间,提高资源发现效率。通过实验验证了所提方法的有效性。

Large number of functionally identical or similar resources exist in cloud manufacturing environment, making it hard to obtain the resources that meet the requirements. In this case, resource discovery based on the functional requirements is studied and a cloud manufacturing resource discovery framework is proposed.First of all, according to formal description of cloud manufac- turing resources, the semantic similarityand weighted similarity is calculated. Finally, from the perspective of functional similarity, the resources are preprocessed with clustering technology, thereby reducing resource searching space and improving the efficiency of resource discovery. At last, experiments verify the effectiveness of the method.
