Then, on the basis of the foundational analysis of entropy and entropy coefficient, the optimized entropy coefficient model is built.
其次在熵及熵权的基本原理分析的基础上，以经济评价指标为基础数据，建立熵权系数优化模型。
The entropy method is adopted to obtain the weight coefficient of the combination model, and analysis of the example result shows that this new model significantly improves the forecasting precision.
并采用熵值法对组合模型的权系数进行求解，实证分析表明该模型使预测精度得到了明显提高，具有良好的预测效果。
