多级模糊模式识别在环境评价中的应用

Application of Multipolar Fuzzy Pattern Recognition in Environmental Evaluation

在多级模糊模式识别模型的基础上 ,提出了一种改进的多级模糊模式识别方法。即针对冶金工业环境的实际情况 ,对原多级模糊模式识别模型中的样本集指标特征值矩阵X进行了修改 ,以国家标准《有毒作业条件分级》(GB1 2 3 3 1 -90 )以及《工业企业设计卫生标准》(TJ3 6-79)中规定的分级指数作为矩阵X的元素 ,运用多级模糊模式识别模型进行环境评价。最后应用改进的多级模糊模式识别方法对某焦化厂焦炉作业环境进行了健康危害评价 ,验证了该方法的正确、有效性。

This paper brings forward a type of improved multipolar fuzzy pattern recognition method on the basis of the multipolar fuzzy pattern recognition model.In the light of the metallurgical industry environment, this method has modified the eigenvalue matrix X of sample set target. With grade indexes defined in 'the Classification of Deleterious Working'(GB12331-90) and 'Sanitary Standard of Industrial and Enterprise Designing'(TJ36-79) as the elements of matrix X, it evaluates the environmental condition by multipolar fuzzy pattern recognition model. Moreover, by applying the improved multipolar fuzzy pattern recognition method to a cokery working environment, it has evaluated the damage of environment to human health. The evaluation results correspond with the actual situation, which proves the validity and correctness of the method.
