摘要(Abstract):
在多级模糊综合评判的数学基础上,提出利用测井资料识别煤田钻孔剖面上煤和岩性的方法。采用频数统计方法,建立第一级评价矩阵及权数向量,以正态分布型隶属函数形成第二级评价矩阵,对评价矩阵与权数矩阵作模糊运算获得评判结果。处理实例证明了这种方法的可靠性。
Having briefly described the mathematic method of fuzzy multilayer comprchensive evalution, the paper discusses emphatically how to recognize the coal types and lithological characters on coal borehole profiles by using this method.The main content in the paper can be divided to the following parts: a.to bulid the first evalution matrix and weigh matrix adopting the frequency statistical analysis; b.to constitute the secord evalution matrix taking the subordinats function with the normal distribution; c.to obstain the evalution results if using fit operators; d.to test this method with a processing example.
