| 摘 要： | 预测方法有多种,找一种操作简单的方法较难。本文利用综合优化软件包1 st0pt,选用几种预测模型,通过对实测数据进行拟合,得出各种预测方法的计算模型,再利用最小二乘法原理,以预测绝对误差平方和最小为目标,给每种预测模型赋予不同的权重,组成规划方程,求出权重数列并组成新的预测模型,再对建筑物进行预测,将得到较好的预测结果。

| Abstract: | As we know,it is difficult to find a simple method to forecast the observations since people have developed many forecast methods.This paper,based on the integrated software named 1st0pt,chooses a few forecast models according to the fitted observation data to obtain the calculation models of forecast methods.Then it utilizes the least squares theory to evaluate different weights for forecast models to make upthe layout equations aimed at the least square sum of errors.At last,it calculates the weights and ... |
