Aiming at the problems of not fully utilizing the data, complicated and changeable of the forecasting target during the traditional predicting, a combination forecasting model based on induced ordered weighted average (IOWA) operator is put forward. This model utilizes IOWA operator to assemble the advantages of the grey systematic and wavelet neural network, analyzes the data based on the square of error and uses Matlab toolbox for optimize calculating to get the best result. The example analysis result shows that the combination model is scientifically and ascendantly.
