To overcome disadvantages of traditional single predication methods in selecting fixed parameters, exponential support was brought in based on IOWHA operator to construct optimal combined predication model of IOWHA operator based on exponential support and to find out the model of IOWHA operator based on mean dispersion that is in consistent with it for study. Moreover, clear definition were given to the predication accuracy as well as the superiority and non-inferiority of the model, and sufficient conditions of the existence of non-inferiority, superior combination forecasting of the model were explored from a theoretical perspective. The example analysis showed that this model was superior to traditional combination forecasting model, for it could use fully the information of each individual method and could improve the prediction accuracy of the model. In a word, it is a kind of superior combination forecasting.
