Interval Combination Forecasting Model of IOWGA Operator for Fuzzy Information Collaborative Correlation
Triangular fuzzy number is an important information expression form of complex and uncertain forecasting system.Three metrics that characterize triangular fuzzy numbers were introduced in this paper,including area type center,area type scat-ter,and midpoint.These indicators reflected the accuracy,fuzzy degree and midpoint characteristics of triangular fuzzy numbers,respectively.On this basis,a new concept of joint correlation coefficient was proposed.Combining the induced ordered weighted geometric average(IOWGA)operator with the joint correlation coefficient of the left and right intervals of the triangular fuzzy number as the optimal criterion,the interval combined forecasting model of IOWGA operator based on triangular fuzzy number and joint correlation coefficients was established.Finally,the validity and stability of the model were proved by example analysis.
