基于灰关联分析的作业环境宜人性评价

在作业环境宜人性评价中 ,评价因素众多且具有不同属性。为了使评价结果尽可能多地体现这些属性 ,且避免多指标权重难以确切分配这一弊端 ,本研究在灰色关联分析法的基础上 ,将宜人性标准的各级别视为区间的概念 ,同时对分辨系数 ρ的取值进行了探讨以避免随意性 ,然后 ,按隶属度最大原则 ,确定作业环境宜人性等级。实例分析表明 ,该方法层次分明、简便实用 ,对作业环境宜人性评价具有较好的适用性。

ASSESSMENT OF WORKING ENVIRONMENT AMENITY BASED ON GREY RELEVANCY ANALYSIS

In working environment amenity assessment, there are lots of influencing factor with different attributes.For the purpose of reflecting the attributes in the assessment and avoiding the trouble of distributing weight to every index, which is difficult generally, according to the principle of grey relevancy analysis, we take the amenity standard as a zone and discuss the coefficient ρ to avoid the random; according to the principle of maximum relevancy,the degree of the working environment amenity is ascertained.The analysis by practical example shows that this method has a preferable applicability in the amenity assessment of working environment.
