Optimization of Port Supply Chain Super Network under Electronic Commerce

This paper establishes a three-layer port supply chain super network model for multiple decision criteria which consists of M suppliers, N port agents and K customers. The establishment of the model is based on the principles of competition in the same layer and cooperation between different layers. Then, from the perspective of suppliers, port agents and customers, we respectively model the optimizing behavior of the various decision makers by using variational inequalities, and we derive the equilibrium conditions of the entire supply chain by using improved projection algorithm. Finally, we prove the feasibility of the model by experiment.
