Application of the optimal combination weighting of moment estimation theory method in the evaluation of mineral resources

In order to improve the reliability and scientific of the comprehensive evaluation of mineral resources，an integrated weighting method taking into account both the objective and subjective influencing factors is presented.This method takes the subjective weights and objective weights as the basic，and makes comprehensive consideration of subjective and objective factors as the object.With the optimal combination model created on the moment estimation theory，the optimal weight of index can be determined by solving the relative importance coefficient of the subjective and objective weight and the optimal solution of the model.On this basis，fuzzy theory is combined with this model and applied to the comprehensive assessment of sustainable mineral resources in Huangshi city.The results show that the outcome is determined by this synthetic evaluation method is more scientific and reasonable，which is in line with the actual situation of Huangshi city.The synthetic evaluation method has an important reference value in the quantitative evaluation.
