矿井通风系统方案模糊灰色信息差异理论评价

Estimation method of fuzzy gray different information theory in comparative study of mine ventilation system

针对影响矿井通风系统质量各种因素因素,采用模糊灰色信息差异理论对该问题进行研究,采用专家打分评价时,某定性指标在不同的通风系统之间产生的差异可能很小。这种微小差异影响了评价效果和准确性,为克服这种微小差异对评价效果的不良影响,在应用模糊综合评判法评价矿井通风系统质量优劣时,引进灰色理论中的差异信息原理扩大信息的差异性。通过实例分析,灰色差异理论的引进提高了模糊综合评判评价矿井通风系统方案的评价效果。

The factors which influence the quality of mine ventilation system have both fuzziness and gray character. And perhaps some qualitative index produces tiny difference in different mine ventilation systems. Because of those qualitative factors, when experts grade＇s method is used, this tiny difference will influence the estimation effect and accuracy. So difference information theory in gray theory is introduced to enlarge the information＇s difference for conquering the adverse effect coming from those tiny differences while fuzzy integrated estimation method is used in estimating the mine ventilation system in this paper. By case analysis, the introduced grey difference theory enhances the estimation effect when fuzzy integrated estimation method is used in estimating mine ventilation system.
