摘　　要：从信息提取视角对多种综合性评价方法进行剖析,发现由此可组合出若干种新的综合性评价方法。通过大量数值模拟实验比较研究无量纲化方法和信息提取法对综合性评价结果的影响。结果表明,综合性评价是一个复杂的过程,关键在于数据的无量纲化处理、权重的计算和结果的稳定性评价,任一部分都会对综合性评价结果产生影响;基于信息提取构建综合性评价指标,可实现不同信息的内部组合,当无量纲化处理恰当时,复合信息提取有助于提高结果的稳定性;用系统方差度量综合性评价结果的稳定性,能客观具体地反映综合性评价方法的优劣,便于不同方法间的比较。This paper analyzes a variety of comprehensive evaluation methods from the perspective of information extraction,and finds that several new comprehensive evaluation methods can be obtained by combining the existing single method.The effects of dimensionless method and information extraction method on comprehensive evaluation results are compared through a large number of numerical simulation experiments.The results show that the comprehensive evaluation is a complex process,and its key lies in the dimensionless processing of data,weight calculation and stability evaluation of results.Any part will have an impact on the comprehensive evaluation results;constructing the comprehensive evaluation indexes based on information extraction can realize the internal combination of different information;when dimensionless processing is appropriate,the compound information extraction is conducive to improving the stability of the results;measuring the stability of comprehensive evaluation results with systematic variance can objectively and concretely reflect the advantages and disadvantages of comprehensive evaluation methods,facilitating the comparison between different methods.
