摘要
资源建模是制造网格中资源集成和共享的前提。首先按资源在制造网格中提供的服务类型对其进行了分类,便于对其分类建模。其次提出了由资源层、资源表示层和资源接口层组成的资源层次模型。资源层包括各种物理资源,表示层使用XMLSchema封装资源数据和信息,接口层使用Web服务描述语言(WSDL)定义对资源的访问操作。该模型用于将制造资源封装为网格节点,使得制造资源可以方便地接入网格中网络共享。最后以企业标准件库的封装为实例验证了该模型的有效性。
Modeling resources is the basis of integration and sharing resources in manufacturing grid. Manufacturing resources are classified according to different grid services they provide to construct their sorted models. A hierarchy model of manufacturing resources, composed of a resource layer, an expression layer and an interface layer, is proposed to address the whole integrating and dynamic sharing of the manufacturing resources. There are all kinds of physical resources in resource layer; resource data and information are encapsulated by XML schema in expression layer; interfaces and operations are defined using web service description language in interface layer. The model is used to encapsulate manufacturing resources as grid nodes, which makes manufacturing resources link to Internet conveniently. At last an enterprise standard part lib is encapsulated using the hierarchy model, which validates its advantages.
