The hybrid method of AHP and group approach to the determination of the index weight of mineral resources

Many issues are often involved in mining rights assessment.Such as the evaluation of the endowment advantages of mineral resources.The index weight of the endowment advantages of mineral resources affects the size of the measurement results of the assessment.Whether the value of the index weight is reasonable or not can reflect the accuracy of the hierarchy of the natural endowment of mineral resources.To take the coal resources as an example,a comprehensive,refined indicator system has been established based on the analysis of the impact of endowments which can reflect the quality of the coal resources endowment.The value of each indicator in the index system of coal resources also has been calculated by the hybrid mathematical methods of AHP combine with group decision.The results have revealed the impact of indicators to the endowment advantages of mineral resources.
