A trading supported manufacturing resource sharing model for manufacturing grid

With the development of grid technology, manufacturing grid (MG) has been proposed to standardize networked manufacturing modes in industry. As manufacturing resources are complicated, heterogeneous, geographically distributed, and owned by different enterprises, manufacturing resource sharing is much more complicated in MG. Resource owners and users have respective requirements, and then MG should provide capability to trade between them. This paper presents a trading supported manufacturing resources sharing model. Organized in a P2P pattern, Hubs, computer nodes deployed core services required, make up the backbone of the model and responsible for aggregating manufacturing resource. In the model, the resource selection process includes two phases: resource discovering and resource trading. Firstly, discover all the potential appreciate resources by multi-keys hashing; Secondly, gain the best appreciate resources by resource trading to make the benefits of both sides best. This model supports many kinds of economic models. The resources owners and users can use any one or some of these models or even combinations of them in meeting their objectives. The procedure of the competitive bidding trade and the method of evaluating tenders are discussed in detail.
