摘　　要：为获得科学、合理的老采空区稳定性评价指标权重,提出了1种基于模糊群决策的赋权方法。首先定义模糊权重的语意标度,决策专家群根据领域知识确定各评价指标的模糊权重语意值,然后综合专家群的意见,将模糊权重语意值转换成三角模糊数,通过解模糊化得到模糊权重的明确值,最后归一化得到老采空区稳定性评价指标权重值。To obtain the scientific and reasonable weights of old goaf stability assessment indexes, a method based on fllzzy group deci- sion- making is proposed. Firstly, the linguistic labels of fuzzy weights were defined, and the linguistic values of fuzzy weights about assessment indexes were offered by expert group according their knowledge; secondly, integrated all views of the experts, the linguistic values were transform into triangular fuzzy numbers, and the crisp values of fuzzy weights were received through defuzzification opera- tion; finally, the weight values of old goal stability assessment factors were determined in normalization process.
