Abstract: 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 combining 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 informatization vendor’s calculation data results verify that the entropy weight of information vendors’ fuzzy comprehensive evaluation model is effective and practical.
