Multicontainer Port Model of Noncooperation Competition

First, the paper analyzes the necessity of a number of competing ports, then moves to a detailed description of container transport supernetwork. The paper analyzes the calculation of transport are cost and establishes a container transport supernetwork defined equilibrium model, in which it extends from the dynamic Stackelberg game model to MPEC model and EPEC model. A port price decision model is gived and multiport model of noncooperation competition is described. Finally, the paper gives EPEC model (equilibrium problem with equilibrium constraints) on the basis of Nash game. It ensures the existence and use of diagonalization algorithm by building a continuous concave function (maximum). By the EPEC model,we have obtained some new conclusion:when the port is making the price strategy,it must take the lower shipper's choice into consideration.
