摘要
用系统工程的观点对公路货运系统进行了综合、动态的分析,在具体分析公路货物运输系统主要影响因素的基础上,分别构建了道路运输需求及供给的子系统动力学模型,该模型可以通过计算机进行模拟,进行公路货运量的预测。
It makeS a comprehensive and dynamic analysis of the road freight transportation system. Considering the major factors of road freight transport, and using the method of system dynamics based on system analysis, it establishes system model-equations of road-freight-transport-demand system and road-freight-transport-supply system, which can be simulated by computer predicting the road freight transportation.
