模糊数学在地层对比中的应用

本文用模糊聚类分析和相对比较法对××媒田的媒层和地层进行对比。模糊聚类分析是先选定参数,用数量积公式求出相似系数,建立模糊等价矩阵,在逐类归并得出动态聚类图,据此图即可分析对比。相似比较法是先建立二元比较级,将备选样本按某种特性排序,再按一定的算法转化为总体排序,求出每个参数名次总和,其最小者就与固定样本最相近。这两种方法均可获得满意的结果。

APPLICATION OF FUZZY MATHEMATICS TO STRATA CERRELATION

In this paper the comparison between the coal seams and stata of X X coal field is made by using the fuzzy cluster analysis and the method of relative compering. In fuzzy cluster analysis first the parameters are chesen; then correlation coefficients are calculated with the dot product equations third fuzzy equivalent matrix is built; last motional cluster figures are obtained by incerporating cne parameter to another. Analysis and correlation can be made by using these figures. In the method of relative comparing,first the comparing order of two porameter is built;then being chosen samples are ordered in term of one of characters and are converted into the total ordering according to a certain calculating method; last the sum of the order of every parameter is calculated. The sample that its sum is smallest is most similar to the fixed sample. The satisfied results can be gained by using the two methods.
