矿井通风系统评价指标权重确定方法对比研究

Comparative Study on Weight Determination Methods of Evaluating Index for Mine Ventilation System

指标权重的确定是矿井通风系统评价过程中关键的一步。在评价指标体系确定的前提下,选取主观赋权法—层次分析法、客观赋权法—熵权法、主客观综合集成赋权法—结构熵权法来确定各指标的权重。对三种方法计算出的权重结果进行分析,运用层次分析法和结构熵权法得到的指标权重较相似;用熵权法通过信息熵得到的指标权重,与上述两种方法得出的权重有较大差异。该结果表明,对矿井通风系统进行正确的评价需要综合考虑评价方法与各方法计算的指标权重。

It is one of key steps to determine index weight in the evaluation process for the ventilation system in mines. In the premise of the certainty of evaluating index system, index weight is determined by the selection among the subjective weighting method - analytic hierarchy process method, objective weighting method - entropy weight method, and subjective and objective comprehensive integration weighting method - structure entropy weight method. The results show that while the index weights obtained by the analytic hierarchy process and entropy weight method are similar, the ones obtained by the entropy weight method is significantly different from the other two. In addition, we need to take all evaluating methods and index weights into consideration in order to correctly evaluate the ventilation system in the mines.
