摘要
在提出阶段序列概念的基础上 ,提出了时数分离的方法 ,用以解决灰色理论中的非等时序列预测问题 .该方法将时间序列、数据序列分离 ,并分别与阶段序列构成模型后 ,进行同步预测 .应用这种方法 ,分析了德兴铜矿 1 #尾矿坝的渗流趋势 ,结果表明这种模型有较好的预测效果 。
The Time\|data\|separation approach is put forward to solve the prediction problem of unequal interval sequence in Grey theory on the basis of the concept of the class sequence, which keeps the time sequence separate from the data sequence, and then combines the time sequence and the data sequence with the class sequence for constituting model , finally synchronously makes prediction. Using this method, the trend of the seepage flow is analyzed in No.1 tailings dam of Dexing Copper Mine. The result shows that the model can make prediction effectively and meet the needs of engineering.
