Study On The Cluster Mode Of Networked Manufacturing Platforms And Its Operation Method

Networked Manufacturing has become one of the main development trends of the modern manufacturing. As the technology-supporting tools, the Networked Manufacturing Platforms (NMPs), which can integrate various resources and have various functions, have got a lot of attentions, and the research and application of NMPs has been becoming a hotpot. With the development of NMP in our country, the isolated-islands problem of NMP is emerging. How to integrate distributed NMPs, and make the distributed resources optimized utilized, is urgent to be considered and solved.In view of the situation, this paper advances the cluster mode of NMPs, which is a loose coupled virtual organization forming by different kinds of NMPs. By the interaction and coordination within the NMPs of the cluster, a lot of distributed resources are gathered to form an integrated resource environment to respond the changeful requirements of customers agilely. The operation process of the cluster mode of NMPs is virtually the process of resources gathering and optimized coordination.Firstly, this paper has a general study on the cluster mode of NMPs. This paper sets up the structure architecture, function architecture and technology architecture of the cluster mode of NMPs, researches the integration technologies of the mode of NMPs, and discusses the self-organization characteristic, the three forms of resources gathering , and the self-optimization mechanism of the cluster mode of NMPs.On the basis, this paper has a pertinent study on the operation mode and relative technologies of the cluster mode of NMPs. Aiming at the integration requirement of the mode of NMPs, this paper discussed the technology of resource integration on the cluster mode, analyzed the requirement expression and resource description method on the basis of RDF technology, and researches the information exchange technology and resource registration and management technology correlated with the integration technology of the cluster mode. Considering the muti-modes of NM, this paper establishes the modes library of NM, and constitutes the classified management architecture of NM modes, NM modes modeling framework, and operation model library of NM. To make the resources optimized combination and integrated operation in the face of requirement of customers, this paper studies the task modeling, resource matching, resource optimization, task scheduling, and workflow management technologies.
