摘要: 基于灰色系统理论扩展了GM(1,1)模型建模方法.给出了一些既改善原始数据列的光滑度,又减少还原误差的变换函数构造条件.首次将灰色动态模型结合变换函数应用于堆浸过程浸出率的预测.结果表明:该方法预测精度高,为实现浸出动力学未来行为的预测和控制提供了一种新的方法.Abstract: The method of developing GM(1,1) model is extended on the basis of grey system theory.Some conditions of the transfer function,which not only improve the smooth degree of original data sequence but also decrease the revert error,were given.The grey dynamic model was first combined with the transfer function to predict the leaching rate in heap leaching process.The results show that high accuracy of prediction can be expected by the method used.This provides a new approach to realize the prediction and control of the future behavior of leaching kinetics.
