Service-oriented manufacturing is the new development of manufacturing systems, and manufacturing supply chain service is also an important part of the service-oriented manufacturing systems; hence, the optimal selection of parts suppliers becomes one of key problems in the supply chain system. Complex network theories made a rapid progress in recent years, but the classical models such as BA model and WS model can not resolve the widespread problems of manufacturing supply chain, such as the repeated attachment of edge and fixed number of vertices, but edges increased with preferential connectivity, and flexible edges’ probability. A core model is proposed to resolve the problem in the paper: it maps the parts supply relationship as a repeatable core; a vertex’s probability distribution function integrating the edge’s rate and vertex’s degree is put forward; some simulations, such as the growth of core, the degree distribution characteristics, and the impacting of parameter, are carried out in our experiments, and the case study is set also. The paper proposed a novel model to analyze the manufacturing supply chain system from the insights of complex network.
Based on the analysis of the manufacturing information's characteristic and the information needs in factories, A system integrated framework named CEIF-vDNC that includes the functions both execution layer and control layer is put forward in the paper. The framework uses vDNC as the information switching and transforming platform between execution layer and control layer, has the functions of the both layers, can ensure the information "No barrage but under control" among factories, work floors and machines. In order to achieve the goal, the core technologies are analyzed; the needs between work floors and machines are integrated; the inner and outer environments such as plan, workers, machines and materials are considered in the paper. So, the framework can reduce the information transacting layers from the point of manufacturing system engineer, and improve the information using efficiencies. Finally, the framework is used in a factory to deal with the engineering problems, and the practice proved it working well, and it brings the factory good economic profits and social impact.
