摘要
构建区间数中点及半径的IOWGA算子最优组合预测模型.引入偏好系数,将多目标的最优模型转变为单目标的最优模型,研究单目标最优模型的定理性质.验证结果表明,基于区间数中点及半径的IOWGA算子组合预测模型优于其他单项预测模型,模型有效.
Constructing the optimal combination forecasting model of the IOWGA operator with the midpoint and radius of the interval number,introducing the preference coefficient,the multi-objective optimal model is transformed into the single-objective optimal model,and the theoretic properties of the single-objective optimal model are studied.The verification results show that,The IOWGA operator combination prediction model based on the midpoint and radius of the interval number is superior to other single prediction models,and the model is effective.
