大坝安全评价中的信息赋权模型

为了充分挖掘大坝安全评价指标样本中的数据信息，以合理确定各评价指标的权重，提出直接由样本数据驱动基于投影追踪分析新型算法的赋权模型，来提取各样本数据信息中所反映的各评价指标的权重。实例计算结果表明，该新模型利用样本数据的信息比常规方法充分，计算结果合理，在大坝安全分析评价和辅助决策中具有一定的推广应用价值。

Information Weighting Model of Dam Safety Evaluation

For full exploitation of information from the samples of dam safety evaluation indexes for reasonable determination of the weight of each evaluation index, a weighting model based on projecting pursuit analysis directly drived by the sample data is proposed for extracting the weights of the evaluation indexes. The calculated results show that the sample information obtained by the proposed model is more sufficient than that by conventional methods, and the results are more reasonable. So the method is worthy of being popularized in dam safety evaluation and assistant decision-making.
