However, under the networked and cloud manufacturing environment, the manufacturing resources have been distributed at different physical positions and heterogeneous platforms. The cloud manufacturing resource is characterized by multilayer, multi-agent and network chain structure. Those manufacturing resources are related and interacted closely. When a manufacturing resource is affected by the market with fluctuation, the other related manufacturing resources will also be affected accordingly. This incidence relation among manufacturing resources is reflected on the supplydemand relationship in enterprises, whose nature lies in the supply chain relationship.
