Research on Multi-index Combination Weight Determination of Dam Safety Evaluation Based on Rank Correlation Coefficient
Jingmei Zhang · Water Resources and Power · 2012
Spearman rank correlation coefficient in nonparametric statistics is applied to determine the multi-index weight of dam safety comprehensive evaluation.It integrates several weight determination methods to obtain combination weight.Each mathematical model has its own assumption,so some faults are inevitable.The combination method can avoid weight distortion caused by these faults.The project example show that the method is feasible and effective.
