摘要
为了解决某铁矿采矿方法设计问题,提出了基于模糊层次分析法的多目标决策模型。根据该矿的地质条件初选出3种开采方案,首先构建多目标决策体系,其次利用模糊层次分析法确定各因素权重,再利用模糊数学确定各因素隶属矩阵并进行综合评判,最后根据隶属度对方案进行优选,优选结果表明阶段空场嗣后充填法为最佳采矿方法。
A multi-objective decision-making model based on Fuzzy Analytic Hierarchy Process is proposed to solve the problem of design of mining method for an iron mine. Three kinds of mining schemes are selected in light of the geological conditions of the iron mine. Firstly, a multi-objective decision-making system is set up and secondly, Fuzzy Analytic Hierarchy Process is used to deter- mine the weight of each factor. Then,fuzzy mathematics is used to determine the membership matrix for the comprehensive evalua- tion. Finally, the scheme is optimized based on the membership de- gree. The preferred results show that the bench open stoping with subsequent filling is the best mining method.
