A New Method of Fuzzy Comprehensive Evaluation on Preponderant Mineral of Area
In view of the fuzziness existed in the evaluation on preponderant mineral of area, integrated fuzzy mathematics theory with traditional evaluation method, a new evaluation model of area preponderant mineral was founded by the method of fuzzy comprehensive evaluation in which the mineral evaluated and the evaluating index were considered as a system. Based on the area mineral resource data, and integrated with analytic hierarchy process (AHP) and the expertise, the eigenvalue and weight of each evaluation index were established; and the compositor of weight of each mineral was established by the optimization identifying system (OIS), which confirmed the value of predominance degree of each mineral in area. Consequently these main predominance mineral were put forward in this area. The result indicated that this comprehensive evaluation model had great practicability, which is easy to be applied, and it is a new method of decision-making on preponderant mineral of area which provided a solid basis for programming area mineral resources in a scientific and reasonable way.
