Dynamic Induced Ordered Weighted Geometric Averaging Operator Combination Forecasting Model Based on Approach Degree
Junjun Mao · Journal of Jiamusi University · 2012
A dynamic induced ordered weighted geometric averaging(IOWGA) operator combination forecasting model based on approach degree was proposed.The model overcame the defect that,in(IOWGA) operator combination forecasting model,optimal weights is in lack of sensitivity when forecasting accuracy sequence changes at different time.And the non-inferior combination forecasting and superior combination forecasting were defined.Under certain conditions,the existence of non-inferior and superior combination forecasting was discussed.Finally,an example shows the effectiveness and feasibility of the combination forecasting.
