) Abstract: A multi-layer evaluation index system was established via the analytic hierarchy process for the mine six-system to evaluate the mine six-system effectively. By applying the comparative method and the scale method, the comparative and determining matrix and the weight for all the matrix elements were made. The mathematical fuzzy theory and the evaluated result were then used to respectively......
