Abstract：As analyzing the regional integration transportation, the various decision-making behaviors and the behavior’s relativity should be investigated. At the same time the flow pattern in the multi-commodity multi-mode traffic network should be predicted in reason. The cooperation and competition among decision-makers can be modeled in multi-tier supply chain. The network optimization model is generally considered to be very appropriate for the prediction of multi-commodity flows in a multi-mode network. Through combining the multi-tiered supply chain model with the network optimization model, one model can be got which combines the freight flow generation, the flow distribution and the path choice. Firstly based on the framework of the multi-tiered supply chain, the decision-making behaviors of manufactures, retailers and consumers are analyzed in turn. Secondly traffic paths are chosen in actual transportation network. Finally, decentralization decision-makings are grouped into the network equilibrium model by using variational inequality. Through explaining the items of the new model, the dependent relationship in various decision-making factors is made clear under the network equilibrium state. The numerical example is given to illustrate the algorithm’s efficiency.
