| 摘 要： | 构建组合预测模型对工程沉降问题进行预测,是一种有效的预测方法,它能综合利用各单一预测模型的有用信息,提高预测精度,但确定其权系数的计算较为复杂。文中利用两种客观赋权方法来计算组合预测模型中的权重,方法简单易懂且使用方便,并通过实例分析证明其优越性。

| Abstract: | It is an effective method which builds a combination forecasting model to forecast the problems ofengineering subsidence. It can utilize the information from every single forecasting methodcomprehensively and improve the prediction accuracy. But the calculation to determine the weights ofcombination forecasting is complicated. There are two kinds of objective weighting method being used tocalculate the weight combination forecasting model. This method is simple to understand and easy to use.The examples show that it can prove its superiority. |
