| Abstract: | The work presented in this paper relates to the prediction of trade distribution ofinter-regions while the transportation costs, commodity supply and demand functions for multiplecommodities are given. Under the condition of the local transportation competition and congestion,a mathematical programming model in an integral form is developed to predict the inter-region nows,supply prices and demand prices by each commodity class. It is proved that the proposed mathematicalprogramming model is equivalent to the spatial price equilibrium problem. An algorithm is proposedto solve this problem. In this article, a numerical example is given to illustrate the application of theproposed model and algorithm. |
