对风险因素的权重的确定，不是单凭主观评判，而是采用熵权系数法进行客观计算。
The weight of the risk actor is calculated objectively by the method of entropy weight coefficient, not only by subjective judgment.
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。
Then, on the basis of the foundational analysis of entropy and entropy coefficient, the optimized entropy coefficient model is built.
另外一种是采用熵权的方法，计算风险因素的综合属性度，进而确定项目综合风险系数，衡量项目面临风险大小。
The another way is use entropy weight to count the risky factor's synthesized weight and measure the risky the project maybe faced.
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。
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.
