| 摘要: |
| 运用多目标最优化理论——SWT法探讨了小麦—天敌—农药—麦蚜系统的优化问题,得到了使经济效益(小麦产量)、环境效益(农药浓度)和社会效益(天敌量)综合最佳的麦蚜种群最优动态参数。结论与决策结果及大田实际表现一致。SWT法结果准确、灵活性大、适用面广且对话性强,可作为专家系统中的一个有力的决策工具,文中给出了SWT法的通用BASIC程序,从而使大小规模的问题解决均成现实。 |

| Abstract: |
| This paper deals with the optimization of wheat-pest compound system using the multi-objective optimization theory-SWT method to get the optimal population dynamics parameters of wheat aphids which can optimize economic returns (wheat yields) , environment benefits (insecticide dosage) and social benefits (enemy numbers) . The conclusions and decisions were in agreement with actual field conditions.SWT method is characterized with accurate results, great flexibility, broad adaptability and fine conversation ability, and can also be used a powerful tool in computer system. Also, the BASIC programme of SWT method was suggested in the paper, thus, making the settlement of various problems possible. |
