关键交通基础设施(Critical Transportation Infrastructure,CTI)仿真中,联合运输是CTI中各子系统间最重要的关联关系之一.为寻求CTI中联合运输系统适用的建模与仿真方法,分析了联合运输系统的概念、组成和各组分的功能,引入了Agent技术,提出了一种基于Agent的联合铁路一公路运输模型,给出了模型的结构,并分析了主要Agent的属性,行为和交互.最后通过仿真试验给出了仿真结果,结果表明模型是合理和正确的.%In Critical Transportation Infrastructure(CTI) simulation,intermodal transportation is one of the most important interdependent relations among the sub-systems of CTI.ln order to seek a suitable method to model and simulate intermodal transportation system,the concepts of intermodal transportation system are introduced and compared;each component and its function of intermodal transportation system are analyzed. Then a new rail-road intermodal transportation model based on Agent is put forward. By designing the structure, attribute,behavior and interactions of major Agent classes in the model, experimental simulation of the model is realized and the simulation results are also presented. Simulation results show that the Agent based rail-road intermodal transportation model is reasonable and right.
