Abstract

Abstract: Combined with the limitation of optimizing indexes theory of comprehensive evaluation,this paper studied the contribution analysis of output value with artificial neural network,then it deletes the indexes which not important or weak influence. It takes important accordance of optimizing indexes in creating model,comprehensive evaluation and making policy etc.

Key words: comprehensive evaluation, neural network, policy decision, optimize indexes

摘要： 笔者针对综合评价建模过程中变量选取方法的局限性，应用神经网络原理对输出值各影响因素进行贡献分析，进而剔除影响不显著或不重要的因素，为模型建立、综合评价和决策过程中选取合适指标提供了可靠依据
