基于FAHP和熵权法的矿井通风方案优选

Optimization of Mine Ventilation Scheme Based on FAHP and Entropy Weight Method

将FAHP法和熵权法相结合建立矿井通风评价模型,对矿井通风方案进行优选。首先通过参考大量研究成果,从技术可行性、经济合理性和安全可靠性3个方面筛选出9个评价指标,通过FAHP法和熵权法分别计算主观权重和客观权重;然后进行综合赋权取得指标权重,同时对原始数据进行归一化处理,计算出评价分值,进而对预选方案进行排序。通过实例验证表明,优选出的方案与实际相符,验证了该评价模型的可靠性。

The mine ventilation evaluation model is established by combining FAHP method and entropy weight method to optimize the mine ventilation scheme.Firstly,by referring to a large number of research results,nine evaluation indexes are selected from three aspects of technical feasibility,economic rationality and safety reliability.The subjective weight and objective weight are calculated by FAHP method and entropy weight method respectively.Then,the index weight is obtained by comprehensive weighting,and the original data is normalized to calculate the evaluation score,and then the pre-selection scheme is sorted.The example verification shows that the optimized scheme is consistent with the actual situation,which verifies the reliability of the evaluation model.
