基于熵权法和模糊评价的信息化厂商评价研究

针对信息化厂商综合评价中各指标的模糊性和不确定性,尝试综合运用层次分析法、熵权法和模糊综合评价法,构建主观权重和客观权重相结合的模糊综合评价法以评价信息化厂商质量。采用层次分析和熵权法分别确定主观权重和客观权重,挖掘指标样本值的客观信息差异,力图使结果更为客观。应用供电企业信息化厂商实际数据测算结果验证了熵权组合权重的信息化厂商的模糊综合评价模型的有效性和实用性。

Research on Informatization Vendors Evaluation Based on Entropy Method and Fuzzy Evaluation

For the comprehensive evaluation indexes of informatization vendors with fuzziness and uncertainty, this paper attempts to apply AHP, entropy method and fuzzy comprehensive evaluation method to construct a comprehensive evaluation method combi- ning with the subjective weights and the objective weights for evaluating the quality of information technology companies. The method adopts AHP and entropy weight to determine the subjective weights and the objective weights, to mine index sample value of the objective information difference, try to make the result more objective. The application of power supply enterprise informati- zation vendor＇ s calculation data results verify that the entropy weight of information vendors＇ fuzzy comprehensive evaluation model is effective and practical.
