本文提出了一个预测网络平衡模型的概念框架，在该模型中，货物运动的产生、分配、模式划分和分配是同时进行的。运输市场的供给方是一个新古典利润最大化模型，需求方是一个空间价格均衡模型，并描述了整合供给和需求子模型的经济机制。理论上的限制施加在模型上的要求，它能够解决大规模的问题也得到解决。
This paper presents the conceptual framework for a predictive network equilibrium model of a freight transportation system in which the generation, distribution, modal split and assignment of freight movements are performed simultaneously. A neoclassical profit maximization model is stated for the supply-side of the transportation market, the demand-side is represented by a spatial price equilibrium model, and the economic mechanism which integrates the supply and demand submodels is described. The theoretical limitations imposed on the model by the requirement that it be capable of solving large-scale problems are also addressed.
