为了提高灰色综合评价方法的客观性,提出了改进的灰色关联法。改进的灰色关联模型以加权灰色关联度和均衡度合成的均衡接近度作为评价准则,既避免了关联度由少数几个较大的关联系数决定的倾向,又采用了客观权系数——熵权,避免了评价中的主观性影响。对平顶山煤业(集团)有限责任公司六矿综采工作面的安全性进行评价,得出了各综采工作面安全性优劣的排序及差异程度,同时指出了各综采工作面在人、机、环境方面存在的问题,并提出了相应的改进措施。
In order to improve the objectivity of gray comprehensive evaluation method, an improved gray relational method is proposed. In the improved gray relational model, the weighted proximity of gray relational degree and equilibrium degree is used as the evaluation criteria, which not only avoids the tendency that the degree of association is determined by a few large correlation coefficients, but also adopts the objective weight coefficient - entropy , To avoid the subjective influence in the evaluation. This paper evaluates the safety of fully mechanized mining face in No.6 mine of Pingdingshan Coal Industry (Group) Co., Ltd., and obtains the rankings and differences of safety in all mechanized coal mining face. At the same time, , Machine and environment problems, and put forward corresponding improvement measures.
