基于博弈论组合赋权的硫化矿山炸药自爆危险性GRA-TOPSIS评价模型

在构建硫化矿山炸药自爆危险性评价体系的基础上, 运用博弈论(GT)协同层次分析法(AHP)所得主观权重和熵值法所得客观权重来获得综合权重, 以提高指标权重的精确性; 将灰色关联分析法(GRA)与逼近于理想解的排序法(TOPSIS)相结合应用于硫化矿山炸药自爆危险性评价。以国内典型硫化矿山为例, 运用GRA-TOPSIS评价模型对炸药自爆危险性展开评价, 所得评价结果与矿山实际情况相符。对比了GRA-TOPSIS评价模型与单独使用TOPSIS、GRA模型以及其他模型的评价结果, 证明了GRA-TOPSIS模型的准确性与优越性。

Evaluation Model of Self-explosion Risk of Explosives in Sulfide Mines Based on Game Theory and GRA-TOPSIS

An evaluation system was established for self-explosion risk of the explosives in sulfide mines. Then, objective weights were derived by using the game theory (GT) in combination with the Analytic Hierarchy Process (AHP), and subjective weights were derived from the entropy value method, so as to improve the accuracy of comprehensive weights. The gray correlation analysis (GRA) in combination with technique for order preference by similarity to an ideal solution (TOPSIS) was applied to evaluate self-explosion risk of the explosives in sulfide mines. Based on the research, some typical sulfide mines in China were taken as examples and self-explosion risk of the explosives was evaluated for the mines by using the established GRA-TOPSIS model, and the evaluation results are consistent with the actual situation of these mines. Based on the comparison of the evaluation results obtained from GRA-TOPSIS model, TOPSIS model, GRA model and other models, it is proven that the GRA-TOPSIS model is superior in accuracy.
