摘要
结合实例,就应用灰色预测方法对累计交通量进行预测时灰色模型的建立问题作了对比分析.分析表明,预测不应仅局限于用 G M(1,1)模型,应根据已有交通量分布情况,建立多种函数的预测模型,经分析比较后选用之同时将静、动态 G M(1,1)模型的预测结果进行了比较。
Com bined the practicalexam ple, the problem of the grey m odelbuildingis analyzed com paratively w hen the cum ulative traffic is predicted w ith the grey prognosism ethod. It is show n thatthe prognosis shouldn'tbe lim ited to the G M(1,1) m odelonly,and m any kinds of function prognosis m odelaccording to the traffic volum e distributioncondition should be considered. And then the m ore reasonable m odel m ay be usedselectively after being com pared. At the m eantim e,the results of the static G M (1,1)m odeland the dynam ic one are com pared. Itis show n thatthe error ofthe back is greater.
