According to the individual forecasting of aviation oil consumption, with taking the minimum value of the angle between the actual value vector and the predicted value vector as a target, we established a combination forecasting model based on the vectorial angle cosine. Through the analysis of an actual example, from the perspective of the effect evaluation indicators of prediction reflect that this combination forecasting model is advantage compared to each single forecasting model.

weighted geometric means combination forecasting is a kind of nonlinear combination forecasting model. Based on absolute of grey incidence, a weighted geometric means combination forecasting model is proposed. Superior combination forecasting, dominant forecasting method and redundant degree are put forward. Under certain conditions the sufficient condition of existence of non-inferior combination and superior combination forecasting are discussed, redundant information is pointed out in a judging theorem.
