Abstract: Aimed at the question of how to evaluate the coal quality,east god produced sales at shenhua group coal coal quality index data as the research object,using TOPSIS and AHP and combined two methods,through constructing the relative deviation matrix to de-termine the index weight,and gives the comprehensive sequencing of various kinds of coal.Structure deviation matrix to determine index weight not only effectively eliminate the dimensional,reduced the subjective arbitrariness of empowerment,the indicators are compara-ble,because on the basis of rational scheme to build at the same time,to achieve the optimal.In the standard and normalization of data put forward the improvement plan,gives the computing method of interval attribute data,improving the application range of the model.
