摘要
使用改进的GM（1，1）模型，即滚动灰色GM（1，1）模型，其中模型初始点是动态且最佳的，并减少了系统误差。通过对攀枝花市2004年～2015年的钒钛磁铁矿供需进行预测后，提高了整个预测的精度和可靠性，最后还给出了攀枝花加深利用钒钛资源的对策和建议。
This paper introduces the trundle gray GM(1,1) model, which is improved from GM(1,1) model and has the best initial point and cuts down system errors. The new model is used to predict the supply and requirement of vanadium and titanium iron ore for Panzhihua area from 2004 to 2015, and precision and reliability of the prediction is enhanced. Lastly, some advices and countermeasure about the deepen utilization of vanadium and titanium iron ore is put forward.
