摘　　要：将诱导广义有序加权平均(IGOWA)算子与正弦函数相结合,提出了诱导广义有序加权正弦平均(IGOWSA)算子的概念,研究了该算子的一些优良性质.同时基于IGOWSA算子构建了新的组合预测模型,从理论上证明了该模型是优性组合预测模型,比单一模型的精度更高.最后给出了实例分析,结果显示其5种误差指标均明显小于各个单一预测模型.Combining the induced generalized ordered weighted average （IGOWA） operator with the sine func-tion, the concept of induced generalized ordered weighted sine average （IOWSA） operator is proposed, and some ex-cellent properties of the operator are studied. At the same time, a new combination forecasting model is establishedbased on IGOWSA operator, and it proves that the model is a superior combination prediction model above the singlemodel. Finally, the example analysis shows that the5 kinds of error indexes are obviously smaller than each singleprediction model.
