COMBINATION FORECASTING MODEL OF TRIANGULAR FUZZY NUMBER BASED ON THE CLOSENESS DEGREE OF CONNECTION NUMBER

针对三角模糊数预测问题,将三角模糊数转化为对应的三元联系数,以三元联系数的贴近度作为最优准则,引入广义加权平均(GOWA)算子,建立了基于三元联系数贴近度的三角模糊数组合预测模型,并证明了该模型为优性组合预测模型。通过实例分析验证了该模型是有效的,能够有效提高预测精度,并对GOWA算子中的参数进行了灵敏度分析。

Aiming at the prediction problem of triangular fuzzy numbers,this study transforms triangular fuzzy numbers into corresponding ternary connection numbers,takes the closeness degree of ternary connection numbers as the optimal criterion,and introduces the generalized weighted average(GOWA)operator to establish the combined prediction model of triangular fuzzy numbers based on the closeness degree of ternary connection numbers,and it proves that the model is a superior combination prediction model.Finally,the sensitivity of the parameters in GOWA operator is analyzed.
