Vendor Managed Inventory (VMI) is an approach in managing inventory between supplier and consumer in an supply chain system. In VMI concept, supplier keeps its inventory at consumer’s warehouse, meanwhile inventory ownership belong to supplier until it is used by consumer. The advantage of VMI is to reduce inventory replenishment ordering process and to reduce the usage of consumer’s warehouse space. Some key factors to achieve VMI success are: coordination, communication, production system and inventory order reliability.When supplier is a subsidiary of consumer, coordination between the two usually puts them not at an equivalent level, especially when supplier’s infrastructure is not as good as that at consumer. This research is a case study at a pharmaceutical company and its supplier which acts as its subsidiary. Information and data gathered by deep interview to all parties responsible for supply chain, production, and inventory at supplier and consumer sides. The results show advantages and obstacles in applying VMI, thus long-term commitment is needed to reach a better performance.

By establishing a two-level symbiotic supply chain system consisting of one supplier and one manufacturer, we use Stackelberg method to analyze the optimal price and revenue model of supplier and manufacturer in the symbiotic supply chain under two power structures in which the supplier and manufacturer are dominant respectively, and analyze the influence of the degree of symbiosis and power structure on the model. Through comparative analysis, we find that: There is a relationship between the income level and the degree of symbiosis in the symbiotic supply chain. The change of power structure will affect the relative benefits of suppliers and manufacturers in the symbiotic supply chain. The manufacturer’s expected unit product revenue will affect the supply chain revenue when the manufacturer is dominant. Finally, the sensitivity analysis of relevant parameters is carried out through an example analysis, and the validity of the conclusion is verified. This paper has a guiding significance for the behavior of enterprises in the cogeneration supply chain.

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.
