矿井通风系统方案模糊灰色信息差异理论评价

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。

矿井通风方案比较的模糊灰色信息理论评价法

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。

Building a Comprehensive Well-off Society in Yunnan＇s Minority Areas A Study of the Prediction on the Differences in Economic Development Indexes

Based on the gray theory and GM （1, 1） model, the various indexes in 2013-2020 are predicted using the data of all indexes of the economic development of Yunnan＇ s 8 minority areas in 2013-2020 and also compared with the standard values of all indexes of building a well-off society in 2020, and the differences between them are analyzed. The purpose of this study is to provide a reference basis for Yunnan province＇ s government to analyze the economic development of the minority areas.
