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...

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.

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。

Mine ventilation system must be evaluated with scientific method in order to ensure the mine safety production and raise economic benefit of corporation. According to the fact that the factors which influence the quality of the mine ventilation system have fuzziness and gray characteristics and there aren't many differences which influence the evaluation effect and accuracy among the qualitative factors between the aforementioned factors, the principle of gray theoretical information difference is used for enlarging...

Mine ventilation system must be evaluated with scientific method in order to ensure the mine safety production and raise economic benefit of corporation. According to the fact that the factors which influence the quality of the mine ventilation system have fuzziness and gray characteristics and there aren't many differences which influence the evaluation effect and accuracy among the qualitative factors between the aforementioned factors, the principle of gray theoretical information difference is used for enlarging the information difference in this paper while the fuzzy mathematics is applied to evaluating the quality of the mine ventilation system in order to surmount the influence of the evaluation effect caused by the less differences among information. Through the analysis of examples, the combination of two methods has raised reliability and accuracy of the evaluation effect of the system scheme.

为保证煤矿安全生产和提高企业经济效益必须科学评价矿井通风系统。因影响其质量优劣的因素既有模糊性,又有灰色特征,为此多应用模糊综合评判法评价。然而因定性因素差异甚微,此方法影响了评价效果和准确性,为克服评价效果受信息差异性较小的影响,在应用模糊综合评判法评价矿井通风系统质量优劣时,引进灰色理论信息差异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评价效果的可靠性和准确性。
