| Abstract: | The three boundary points of triangular fuzzy number sequence are transformed into three equivalent index sequences:area type center, area type divergence and centroid. Combined with the generalized induced ordered weighted average (GIOWA) operator, the L2 norm of area type center, area type divergence and centroid is selected as the optimal criterion to establish a new superior combination forecasting model of triangular fuzzy numbers, and it is proved that the new model is a superior combination forecasting model. Through the example analysis and comparison, the model is further verified to be effective and feasible, which can effectively improve the prediction accuracy. Finally, the sensitivity analysis of the parameters in GIOWA operator is carried out. |
