综合评价模型自动选择研究

摘要

It is difficult to select proper comprehensive evaluation models. In order to solve this problem, key attributes and typical comprehensive evaluation models have been selected which play an important part in model selection. Then a model selection method has been proposed which constructs the decision tree based on C4. 5 by calculating the entropy of the selected key attributes. Finally the effectiveness of this method has been confirmed by empirical study on city and municipal economy comprehensive evaluation issues which provide the support for decision making.%针对综合评价模型选择难的问题,从决策者、决策问题和决策模型3个角度出发,提炼出对模型选择有影响的关键属性,并筛选出典型的综合评价决策模型.利用C4.5方法计算各关键属性区分度构建相应决策树,生成相应决策规则.按照生成的决策规则及评价问题关键属性的取值实现模型自动选择.最后通过对城市与市政经济评价问题的实证分析,验证该方法的有效性,为决策者决策提供辅助与支持.
