摘要
为解决指标决策法赋权失真及突变决策重要性排序的主观偏差,应用组合思想,基于模糊AHP评判对比矩阵解算重要度排序向量,进而构建科学重要度的突变评价系统来实现更优评判。以夏甸金矿特型灾害矿体的回采方案选择为例,设立13个评价指标来实现系统全面评判,设置9个次级指标来提高解算精度,计算出上向水平分层充填法、分段空场法、环境再造诱导崩落法3个预选方案的评价值依次为0.988,0.992及0.956,最终确定分段空场法为最佳方案。
In order to solve the problems of weighting error in the multiple-criteria decision-making and subjective bias in importance ranking during the decision-making with catastrophe theory,a combined concept was used to resolve the matrix based on fuzzy AHP method and the vector for importance ranking was obtained.Then a scientific importance evaluation system based on catastrophe theory was constructed.The evaluation system was applied in the selecting the proper stoping method for Xiadian Gold Mine with geological conditions being extremely unfavorable for ore exploitation.13 criteria were set for performing a comprehensive evaluation and 9 sub-indexes were decided for improving the resolving precision.After calculation,the evaluation value for the preliminarily selected three mining methods,including upward horizontal slice stoping and filling method,sublevel open stoping and induced caving mining based on mining environment regeneration,were 0.988,0.992,0.956 respectively,indicating that the sublevel open stoping mining method is the optimum mining method for the gold mine.
