Research on Supply Chain Contract Coordination Simulation Based on Swarm

In order to study the effects of the contract coordination in the supply chain, the complex adaptive system (CAS), Agent model-building and supply chain theories were introduced, and the competitive rules and assumption conditions of simulation of the corporations in the supply chain were described. Then competitive environment of the supply chain was constructed on the Swarm simulation platform, and then the three types of contractspsila processes (the optimization of the supply chain, the optimization of the supplier and the retailer) were simulated. The results indicate that an appropriate contract can make all the corporations beneficial and almost maximization, and it can coordinate and promote the whole supply chain continuous and healthy development, which is the goal of contract design. The results have strong practical and instructional significance.
