基于IOWA算子与向量夹角余弦的联系数型区间组合预测

Connection Number Interval Combination Forecast Model That Based on Induced Ordered Weighted Averaging Operator and Vector Angle Cosine

根据联系数与区间数的性质将区间数转换为联系数的表示形式,进而结合诱导有序加权平均算子与向量夹角余弦建立了基于联系数的区间型组合预测最优化模型,继而定义了联系数型区间组合预测模型的优劣性,最后通过实例验证与评价所建立的联系数型区间组合预测模型的有效性,实证结果表明本文所创建的方法是优性的与有效的.

First of all,the text converts interval number to the representation of connection number according to the characters of connection number and interval number. Secondly,the optimization model of connection number combination forecast is established,which is based on induced ordered weighted averaging operator and vector angle cosine. Then,the merits of the connection number interval combination forecast model are defined. Finally,an example of the connection number interval combination forecast model set up with validity is verified,and the empirical results show that the method is excellent and effective.
