摘要
介绍了基于灰色关联分析的动力煤评价方法,并阐述了其原理和模型。选用我国主要动力煤产区的5个典型煤样作为评价对象,根据中华人民共和国煤炭行业标准GB/T15224.1-2004及国内外相关文献,将动力煤炭标准分为五级,采用灰色关联分析方法对动力煤质量进行评价,并与模糊综合评判及BP神经网络评价方法对比,阐述了各种评价方法的优缺点,通过对比各评价方法的结果,得出灰色关联度分析方法是一种简单有效的动力煤质量评价方法。
The paper proposed a method for power coal quality evaluation based on gray relational analysis. The basis theory and model was introduced. Selected 5 coal samples from mining areas of our country as evaluation objects. Based on China coal industry standard GB/ T15224.1-2004 and domestic and international reference, the standard of power coal is divided into 5 grads. Use the gray relational analysis method to evaluate power coal quality, and compared the methods with fuzzy-discerning method and BP neural network method, discussed the merit and shortcoming of each method. Through compared those results of each evaluation methods, it is obvious that Grey relational analysis method is a kind of simple and valid method for power coal quality evaluation.
