Decision-making for Flood Control in Open Pit Coal Mines Based on Multi-level Fuzzy Evaluation
Gao Hong-jiang · 2011
In order to select the reasonable flood control works in open pit coal mines,hierarchical structure of flood control evaluation indicators was established according to the requirement of multi-level fuzzy evaluation.Weight allocation among indicators in different levels was determined by analytic hierarchy process and the single factor evaluation matrix was gained by the expert scoring method.Finally,the goodness of every alternative was obtained by the synthetic operation of the fuzzy vector.The result shows that the method is reasonable and effective,which has an important value in the decision-making for flood control in open pot coal mines.
