摘要
为更合理的确定影响大柳塔煤矿通风系统影响因素的权重,通过分析其特点,并结合在试验平台的实践,建立了通风系统层次评价指标体系。在层次分析法(AHP)判断矩阵的构造上,采用3标度法对传统的9标度法进行改进,克服了9标度法采用模糊字眼表示两元素关系的困难,并运用matlab数值模拟快速确定了评价指标体系中准则层和子准则层各指标的权重。对比分析表明,改进AHP法提高了煤矿通风系统评价的效率和准确度,具有更强的实用性。
To determine the influence factors weights of ventilation system in Daliuta coal mine more reasonably,an ventilation evaluation system was established by analyzing the characteristics of this mine and combining with experimental experience.Based on the structure of AHP judgment matrix,three-scale judgment method was utilized to improve the traditional nine-scale method.The difficulties of ninescale method that fuzzy words were used to present relations between the two elements were overcome.And matlab numerical simulation was adopted to quickly determine the weights of each index of rule layer and the child ones in the index system.The results showed that the improved AHP enhanced the evaluation efficiency and accuracy of the ventilation system and had a stronger practicability.
