The Application of AHP in Mine Water Treatment Process Optimization

Through expounding the method of selecting mine water treatment scheme reasonably based on analytic hierarchy process(AHP),aiming at many indexes of affecting the selection of mine water treatment scheme,three hierarchical structure model of optimum selection and evaluation index system are established by taking economic benefits,technical performance,management benefits as the criterion.The judgment matrix by the comparison of two factors in same layer is established,and the relative weight of index is calculated by characteristic root of the judgment matrix,and finally the consistency of the result is inspected.Priority ordering of the scheme is achieved by comprehensive evaluation with the dimensionless process of evaluation index,which provides reference to make a decision scientifically and reasonably.
