综采工作面环境状况灰色熵权聚类分析

Grey Entropy Weight Clustering Analysis of Environment State of Fully Mechanized Mining Faces

基于灰色系统理论建立了综采工作面作业环境聚类指标体系。从人对作业环境的适应度出发,确定不同作业环境灰类的灰数,从而给出不同灰类的白化函数。利用现场实测环境参数,根据灰色熵权分析给出各指标信息熵,计算出各指标的聚类权,最后计算出各对象对应的聚类系数,确立了作业环境状况。

Based on the grey system theory, establish clustering index system for operating environment of fully mechanized coal face. According to people＇s fitness degree on operating environment, to determine the grey number of grey classification for different working environments and then to give whitenization weight functions of different grey classifications. Using the field measurement of the environmental parameters and according to grey entropy weight analysis the entropy of each index was given, and then the weight of each index clustering was calculated, finally the clustering coefficient of each object was calculated, the working environment was established.
