基于相似度的三角模糊数组合预测模型

Triangular fuzzy number combination forecasting model based on similarity

通过对三角模糊数进行研究分析,将三角模糊数用等量信息的三个指标进行替代,采用三角模糊数的相似度作为最优准则的度量指标,并引入广义诱导有序加权平均(GIOWA)算子,建立了基于三角模糊相似度的GIOWA算子的变权系数的三角模糊数组合预测模型.通过数值实验表明,该方法有效可行.

In this paper,the triangular fuzzy number is studied and analyzed,and the triangular fuzzy number is replaced by three indexes of equivalent information,the similarity degree of triangular fuzzy numbers is taken as the measurement index of the optimal criterion,the generalized induced ordered weighted average(GIOWA)operator is introduced,and the triangular fuzzy number combination prediction model based on the variable weight coefficient of GIOWA operator is established.Numerical experiments show that this method is effective and feasible.
