白云鄂博铁矿石种类的划分与边界品位的多目标优化

Multitarget Optimization of the Classification and the Cut-off Grade of Baiyunebo Iron Ores

依据白云鄂博铁矿采选实际生产资料，采用数理统计方法建立了矿石储量及选矿比等各种数学模型，设置了总利润、总现值和精矿量３个优化目标函数，用Ｌｏｔｕｓ—１２３软件功能和模糊数学综合评判方法，对该类矿石划分及边界品位进行了多目标优化研究。

Abstract On the basis of the real production data of Baiyunebo iron Nine .various mathematical models forore reserve and concentration ratio have been established by the mathematical statistics method.Withthe total profit,total current value and concentrate amount as the target functions and by making use ofLotus-123 software functions and the comprehensive evaluation method of fuzzy mathematics,the multiple target study has been carried out on the ore classification and the cut-off grade.
