摘要
对预测误差平方和最小为原则的固定权重最优组合预测模型进行改进,提出了一种应用于移动通信网业务量预测的变权组合预测方法。通过4种预测方法对某地业务量进行预测并比较其精确度,结果表明改进的变权组合预测方法取得了较高的预测精确度。
Based on the improvement of the optimum combinational prediction model in which the minimum squared sum of predicted errors is adopted, a combinational prediction method suitable for traffic prediction of mobile communication networks is proposed in this paper. Four prediction methods are used to predict the traffic in a region and their precision is compared. Results show that the proposed method has higher prediction precision.
