| 摘 要： | 在预测模型的均值和稳定性基础上,建立了多目标组合优化模型,并以黑龙江九三地区35年的大豆产量数据为例,利用该地区大豆单产的Logistic模型和大豆产量与气象因子的逐步回归模型建立了多目标组合优化模型,并计算出最优解.结果表明,该组合模型没有最优点,而有非劣解.该方法对提高模型的精度,指导大豆生产具有重要意义. |
| 关 键 词： | 黑龙江 大豆 多目标组合模型 优化模型 |

| Abstract: | The paper sets up multi-objectives forecasting model,according to two precision indicators. Then multi-objectives forecasting model of the Logistic model and stepwise regression model of soybean yield in Heilongjiang is established and Computed. The result shows that there is not Ideal point,but there are some non-poor solution.In the end,by the combination forecasting and multi-objectives optimumal weight number combination forecasting model is established and precision is recreased. This is very important for guidance soybean produce. |
| Keywords: | heilongjiang soybean multi-objectives combination forecasting model optimal model |
