简介：在全球经济系统，每经济由增加它的国际贸易刺激它的粗野国内产品(GDP)的生长。用GDP和外贸的流动数据的变化分析，我们发现GDP和外贸被外部力量统治并且由对方开车。由排除联系贸易相关性度的影响，GDP和外贸的全部的体积崩溃很好进幂定律功能。经济的全部的贸易体积与贸易搭挡的数字可伸缩，并且它在它在一张指数的表格的贸易搭挡之中是分布式的。合并了这些实验结果的模型能同时集成GDP的生长动力学和在GDP和加权的国际贸易网络之间的相互影响动力学。

简介：在这篇论文，我们为在铁路网络上模仿火车运动建议一个改进散步模型。在建议方法，行人们代表火车。改进散步模型是一种基于网络的模拟分析模型。用行人运动的一些管理规则，行人能动态地在车站决定它的离开和到达时间。以便测试建议方法，我们在铁路网络的部分上模仿火车运动。数字模拟和分析结果证明改进模型是为在铁路网络上模仿火车运动的一个有效工具。而且，它能很好捕获在铁路交通安排的火车的典型行为。
