【摘要】 目的:给出2005年全国大学生数学建模竞赛C题的解答.方法:利用二维插值、区域圆形覆盖算法、层次分析法(AHP)中的1—9标度法和独立样本t检验,分别对非等级预报和等级预报情形建立了点降雨量和面降雨量预报方法评价模型.结果:得到了题中两种预报方法优劣的比较结果.结论:降雨量预报方法1优于方法2.更多还原

【Abstract】 Objective: To solve the problem C in the CUMCM 2005.Methods: Based on the interpolation method of 2-D,circular covering of domain,one-ninemethod of analytic hierarchy process(AHP) and independent-samples T test,mathematical models of evaluation for point rainfall and area rainfall are established for the case of non-graded forecast and the case of graded forecast.Results: The evaluating result of the two methods of rainfall forecast is obtained.Conclusions: The first method is better than the second method.更多还原
