组合赋权的GC-TOPSIS在矿山开拓方案优选中的应用

Application of GC-TOPSIS Combination Weights in Optimization of Mine Development Plan

为将数值决策更好地应用于实际矿山的开拓方案优选中,在综合考虑开拓方案基本要求、影响因素及指标选取原则的基础上,构建了含经济、技术、安全及环境保护4个方面15个指标的矿山开拓方案优选评价指标体系,采用AHP-CV组合赋权的GC-TOPSIS法对贵州某锰矿开拓方案进行了优选,结果表明:层次分析变异系数组合赋权法能更全面客观地确定评价指标权重;经灰色关联理解法计算,备选方案与理想方案的接近程度依次为方案三>方案一>方案二,与理想方案的远离距离方案三最小,因此,相对贴近度最大的方案三为最佳开拓方案,此方案与该矿通过经济技术综合分析所确定的方案一致。

In order to better apply numerical decision-making to the optimization of actual mine development plan,on the basis of comprehensive consideration of the basic requirements,influencing factors and index selection principle of development plan,the evaluation index system of mine development plan optimization with 15 indexes in four aspects of economy,technology,safety and environmental protection was constructed.The GC-TOPSIS method of AHP-CV combination weights was used to optimize the development plan in a manganese mine in Guizhou Province.The results show that,the combination weights method can determine the evaluation index weight more comprehensively and objectively;through the calculation of GCTOPSIS,the order of close degree between the alternative scheme and the ideal scheme is scheme 3>scheme 1>scheme 2,namely,the scheme 3 has the the smallest distance from the ideal scheme.Therefore,the scheme 3 with the largest relative close degree is the best development plan.The result is consistent with the plan determined by the comprehensive economic and technological analysis of the mine.
