【摘要】 在线性组合预测模型的前提下,首先提出了广义加权算术平均预测有效度的概念.其次分别在样本区间、预测区问以及总区间上建立了以一阶预测有效度为准则的广义加权算术平均组合预测模型,并且对非线性组合预测模型进行相应的变换,将其转化为线性规划模型问题来求解.最后,将新模型应用于实例中,并说明其有效性.更多还原

【Abstract】 This paper first presents the concept of generalized weighted arithmetic average forecast effective measure based on the linear combination forecast model.Followed we establish the generalized weighted arithmetic average combination forecasting model in the sample intervals,prediction intervals and the total range,respectively,which are use order first-order forecasting effective measure as the criterion.Then we turn the nonlinear combination forecasting model into the linear programming model, and eventually we can use existing linear programming software to solve the linear programming model. Finally,the new model is applied to the instance,and state its superiority.更多还原
