Combination Forecasting of Fuzzy Forecast

In this paper, we first give three kinds of model of fuzzy forecasting: fuzzy linear regression forecasting, Quadratic polynomial fuzzy regression forecasting and fuzzy time series self-regression forecasting, then we introduce the combination forecasting of fuzzy forecast,and give two kind of combination forecasting of fuzzy forecast, one is the linear combination forecasting of fuzzy forecasting based on fuzzy least square, the another is the nonlinear combination forecasting of fuzzy forecast based on Choquet fuzzy integral.
