摘要
运用粗糙集对矿井通风系统合理性评价指标体系进行约简,去除冗余指标,并求出约简指标体系中各指标的重要性,进行归一化后,作为未确知测度评价模型的指标权重系数。不仅减少了未确知测度评价的计算量,也为其权重确定问题提供了一种新的客观解决办法。同时,结合邯郸市峰峰矿区15个矿井的实测数据验证了该模型的有效性。
The paper applied rough set theory to reduce the mine ventilation system rationality evaluation index system, remove redundant indexes and calculate the importance of each index in the reduced index system. This practice not only reduced the calculation amount of unaseertained measure evaluation model but also provided weight coefficients for the model, which is a new objective solution for its weight determination problem. And, according to the practical data of Fengfeng Mining in Handan, the paper verified the validity of the model.
