综采工作面参数系统多维灰色状态模型

针对综采工作面影响因素多、系统复杂的特点，深入分析了综采工作面输入、输出参数系统。以综采工作面统计资料为基础，应用模糊数学理论、灰色关联分析方法和层次分析权重确定方法对众多输入参数进行了量化处理和综合，并进一步应用灰色建模理论，建立了综采工作面产量和效率两项输出参数与输入类参数的灰色状态模型-GM（0,4）模型。经验证，该模型具有一定的精度，对煤矿生产具有指导性作用。这为综采工作面参数系统研究提供了一条新方法。

A multi-dimensional grey state model on parameter system of fully mechanized coal faces

In view of the fact that fully mechanized coal faces have many influence factors and its complexity in system,the paper thoroughly analyses the input and output parameters of fully mechanized coal faces.On the basis of the statistical data of fully mechanized coal faces,a number of input parameters are dealt with quantitatively and comprehensively according to fuzzy mathematic theory,the grey interaction analysis method and the method of step weight analysis.By the further application of grey modeling theory,the multi-dimensional grey state model GM(0,4) model with the production and efficiency as the two items of output and input parameters are established.It is proved that the  model has certain accurac y and it has certain guiding effect for production on fully mechanized coal faces.This study provide s a ne w approac h fo r studyin g the parameter system of full-mechanized coal faces.
