| 摘 要： | 运用系统动力学理论和方法,建立了各种交通运输方式在综合系数为时不变时的自组织演化动力学模型.对只有两种运输方式(公路运输和铁路运输)的情形进行了稳定性分析和演化态势分析,并通过数值仿真验证了理论分析结果.结果表明:两种运输方式的竞争合作系统的演化方向存在多种可能,演化结果与竞争合作效应紧密相关.努力放大系统中的合作效应,使有益的运行模式逐渐占据优势可以引导系统向正确的方向不断发展.

| Abstract: | A dynamic model of the self-organizing evolvement about various transportation modes with time-invariant comprehensive coefficient is established based on system dynamics.This paper analyzes the stability and evolvement trend of the model combined by two transportation modes(railway transportation and road transportation),and simulation validate the results of the theoretical analysis.The results indicate that the evolvement directions of the competition and cooperation system of two transportation modes ha... |
