摘要
针对在传统AHP法确定富水性预测评价指标权重时,采用1~9、0~2、0.1~0.9标度法构建判断矩阵过程中存在的问题,引入了新的五标度法。使得在构造判断矩阵时,更加符合专家打分心理,也避免了信息量丢失以及对原始判断矩阵进行间接的数学处理或变换。应用改进的Weber-Fechner定律评价数学模型,对葫芦素井田延安组三段3-1煤层顶板砂岩富水性进行预测评价。结果表明,改进的AHP法确定富水性预测评价指标权重时是有效的,同时也为富水性预测评价提供了一种新方法。
In allusion to the water yield property prediction assessment index weight determination through the AHP,to solve existing issues in the process of 19,02 and 0.10.9 three scales judgment matrix structuring,the new five scales method introduced.Thus more accord with specialist scoring mind during judgment matrix structuring,also avoid information content loss and can carry out original judgment matrix indirect mathematical treatment or manipulation.Through the improved Weber-Fechner＇s law assessment mathematical model has carried out prediction assessment for No.3-1 coal roof sandstone water yield property in the third member of the Yan＇an Formation,Hulusu minefield.The result has shown that the water yield property prediction assessment index weight determination through improved AHP is effective,and provided a new method for water yield property prediction assessment.
