变权模糊综合评判优选采矿方法

摘要

采矿方法选择是一个典型的模糊决策问题.影响采矿方法选择的诸多因素中,既有定量指标也有定性指标.为了克服传统技术经济评价法的局限性,达到全面、准确的择优效果,提出使用变权模糊综合评判优选采矿方法.该方法不但解决了采矿方法选择的定量评价问题,而且通过变权法能够根据各评估值的大小适当调整各因素的权重,突出评估值较低项的不完善性,因而使得综合评判结果更具有合理性、科学性.%It is a typical fuzzy decision-making problem to select the mining method. There are quantitative indicators and qualitative indicators in many mining method selection factors, in order to overcome the limitations of traditional mining methods selection, achieve a comprehensive and accurate result, the variation weight,fuzzy comprehensive evaluation in selecting the mining method is proposed. Not only the new method solves the problem of quantitative assessment for mining methods, but also variable weight method can adjust the weights according to the size of the assessed value of each factor, thus emphasize the imperfection of the factor. Finally the comprehensive evaluation result is more rational and scientific.
