摘　　要：根据话务数据自身的特点 ,提出了一种比以往模型更能反映话务数据特点的模型 ,并且研究了如何用含有野值点的数据集稳健地建立模型 .最后介绍了如何找出话务数据中的野值点和如何预测话务量 .According to features of traffic data, a model which can express features of traffic data and is better than old ones, is put forward. And how to build model robustly by using data set including outliers, is also researched. Finally, the problems of how to pick out outliers from the traffic data and how to forecast traffic flow are discussed.
