Networked manufacturing-based supply chain operation model and contract research

The research presented the supply chain operation model based on networked manufacturing. It employs the Object-oriented Petri Net(OPN) to analyze the process of supply chain. The model of each object who takes part in supply chain operation was designed and the synthetical model was presented. Then, some properties such as deadlock, overflow and conflict can be analyzed. In such supply chain operation, the revenue-sharing contract has to be used for analyzing the coordination relation among the objects which take part in the supply chain operation. So, the two-stage supply chain coordination model was built. Through Stackelberg game analysis, some factors such as revenue-sharing proportion, order quantity, wholesale price were discussed. Then the coordination strategies were found. Numerical simulation based on MATLAB was used to get the results in this kind of contract. It also proved that the supply chain had great profit loss when punishment factor existed.
