预测系统
灰色预测模型称为CM模型,G为grey的第一个字母,M为model的第一个字母。GM(1,1)表示一阶的,一个变量的微分方程型预测模型。GM(1,1)是一阶单序列的线性动态模型,主要用于时间序列预测。 一、GM(1,1)建模 设有数列 共有 个观察值 对 作累加生成,得到新的数列 ,其元素 (5-1) 有: 对数列 ,可建立预测模型的白化形式方程, (5-2) 式中: ——为待估计参数。分别称为发展灰数和内生控制灰数。设 为待估计参数向量 则 按最小二乘法求解, 有: (5-3) 式中: (5-4) (5-5) 将(5-3)式求得的 代入(5-2)式,并解微分方程,有 (1,1)预测模型为: (5-6)(gray forecasting model called CM model, the G-gray of a letter, the M model for the first letter. GM (1,1), a band of a variable type of differential equation models. GM (1,1) is a sequence of single-band linear dynamic model, mainly for time series prediction. A GM (1,1) model series with a total value of observation for the cumulative production, to a new series of its elements (5-1) : The series, we can establish the prediction model albino form of equation (5-2) where :-- to question the estimated parameters. The development will be known as the gray and hygiene control within a few gray. Set parameters to be estimated according to Vector least squares method, are : (5-3) where : (5-4) (5-5) (5-3) that obtained in lieu of income (5-2)- and solutions differential equations, (1 1) Fore)

对美国由次贷危机引起的金融风暴进行了研究,分别建立了次贷危机产生机理的模型和金融风暴的判定模型,并用计算机对模型进行了仿真。通过仿真分析得出了利率和房价的变动是形成次贷危机的直接原因,而信心指数却是形成危机的根本原因的结论。况,实现城市平面十字路口的微观仿真,通过仿真得到信号灯的最佳控制方式与这一控制方式下的交通拥堵情况。然后在取消左转的条件下从路网的角度分析道路交通流,通过对路网模型的分析,针对其较大的复杂度和边界缺陷,我们建立了其等效模型。改变进入系统的车流的性质仍然在单个十字路口建立模型进行仿真。经过两个模型的对比,我们得出“取消左转”这一方式有利于改善道路交通拥堵问题。最后提出其他可行的“无左转”交通流组织形式,并进行简单分析。(Subprime mortgage crisis matlab simulation)
