Comprehensive evaluation on suppliers of Aircraft based on grey Bayesian network model

Based on systematic analysis on comprehensive evaluation factors of suppliers of Aircraft, the paper established a multi-level index system on evaluation factors of suppliers; the author solved for parameter distribution problem by means of Maximum Entropy Model, and proposed methods of dealing with uncertain information in the evaluation process according to grey system principles. Finally, the paper provided a practical theory and tool for the comprehensive evaluation of suppliers based on the quantitative evaluation of every network node after inference in Bayesian network.
