摘要
针对民航运量数据提出对主体ARIMA模型的残差序列进行二次建模以修正原模型的精度和适应性,引入遗传进化因子来估计二次建模的参数,利用一个典型的民航运量时间序列进行建模仿真,通过对仿真建模的结果评价表明该种建模方法是有效的,能够提高模型的预测精度和改进模型的适应性。
Due to the seasonal characteristics of civil aviation transport demands, a satisfactory estimation accuracy cannot be obtained by an ARIMA model only. Thus, a residual secondary modeling method is pro- posed to improve the accuracy and adaptability of the primary ARIMA model. Further, a genetic operator is introduced to the solution process of the model. With the typical data from the real world, test is conducted by simulation. Results show that the forecasting accuracy and adaptability are significantly improved. In other words, the proposed method is effective.
