为更加合理地评价矿井通风系统,基于属性区间识别理论构建矿井通风系统技术可行性、经济合理性与安全可靠性预测与分级的属性识别模型.首先确定矿井通风系统评价指标与分级标准,给出矿井通风系统的属性空间矩阵;通过构造属性测度函数以计算单指标属性测度,采用层次分析法(AHP)计算各判别指标的权重,将单指标属性测度转化成综合属性测度;利用置信度识别准则对矿井通风系统进行属性识别.实例分析结果表明:属性数学理论能够很好地解决具有多个模糊属性问题的综合评价.
In order to evaluate the mine ventilation system more reasonably and to build the attribute identification model of mine ventilation system technical feasibility, economic rationality and safety reliability prediction and classification based on attribute interval identification theory, firstly, the mine ventilation system evaluation index and classification standard are given, The attribute space matrix of mine ventilation system is constructed; the attribute measure function is constructed to calculate the measure of single index attribute; the analytic hierarchy process (AHP) is used to calculate the weight of each discriminant index; the single attribute measure is transformed into the comprehensive attribute measure; The attribute recognition of mine ventilation system is carried out.Example analysis results show that the attribute mathematical theory can well solve the comprehensive evaluation with multiple fuzzy attributes.
