云制造资源的一种发现机制

A discovery mechanism of cloud manufacturing resource

针对当前现代制造模式研究热点的云制造,结合网络化制造资源发现原理及方法,提出了一种云制造资源的发现机制及其实现方法。首先分析了云制造基本内涵,给出了一种通用的四层体系结构,明确了云制造环境下制造资源的分类及特征,结合语义Web服务和OWL-S技术,提出了一种基于语义Web和本体知识的制造资源发现框架,并给出了一种基本的匹配策略和相似度算法。在实验的基础上,将对该发现机制与其他发现机制进行比较,结果表明这种方法查全率和查准率较高。

The cloud manufacturing is the current research interest in the modern manufacturing mode,combined with the discovery principle and method of networked manufacturing resource,a discovery mechanism and realization methods of cloud manufacturing resource is put forward.By analysing the basic connotation of the cloud manufacturing,a general four layer system structure is given,and manufacturing resources classification and characteristics is also determined in cloud manufacture environment.Combining semantic Web services with OWL-S techniques,a manufacturing resource discovery framework based on the semantic Web and a matching strategy and similarity algorithm is given.Experiments of comparing this discovery mechanism with other established methods,show that the recall ratio and precision is higher by using this method.
