说明: 基于MATLAB的组合模型
在港口吞吐量预测中的应用
以某港1998--2007年集装箱吞吐量为实测数据,建立其集装箱吞吐量的灰色理论、三次指数平滑、三次多项式
等预测模型,在MATLAB下,对比该港集装箱吞吐量各模型预测拟合值与实际值的差异。分析了差异产生的原因及其单一预
测模型的局限性,提出了港口集装箱吞吐量组合预测法。其预测误差明显低于其它单模型。运用组合预测模型.可以降低误
差。提高预测精度。(A combination of MATLAB-based model in port throughput prediction of a Hong Kong 1998- 2007 container throughput for the measured data, the establishment of its container throughput of the gray theory, the three exponential smoothing, prediction models, such as cubic polynomial in MATLAB, the contrast of the Hong Kong container throughput of fitting the models to predict the value of the difference between the actual value. Analysis of the causes of differences and the limitations of a single prediction model, the combination of port container throughput prediction. Its prediction error was significantly lower than other single model. The use of combination forecasting model. Can reduce the error. Improve the prediction accuracy.)

物元分析法(matlab)
说明: 物元分析法由我国数学家蔡文在 20 世纪 80 年代提出. 应用物元法建立多指标评价模型,可以针对复杂问题建立形象化模型,定量化得出评价结果,从而较完整、准确地反映事物的综合水平。利用matlab编程,进行如下步骤计算:1、待判物元的确定;2、经典域、节域的确定;3、关联函数;4、综合关联度(Matter-element analysis method was put forward by Chinese mathematician Cai Wen in 1980's. Applying matter-element method to establish multi-index evaluation model can establish visualization model for complex problems and quantify the evaluation results, so as to reflect the comprehensive level of things more completely and accurately. Using MATLAB programming, the following steps are calculated: 1. determination of the subject element to be judged; 2. determination of classical domain and node domain; 3. correlation function; 4. comprehensive correlation degree)
