Research on the application of Bayesian Network in macro quality evaluation system

Serious regional and systematic product quality problems frequently occur in China in recent years, and does great harm to people´s health and safety. Only scientific and accurate macro quality evaluation can the potential risk on product quality safety be found timely. Earlier warning and treatment on significant product quality problems will avoid their harmful results as possible. This article brings forward a macro quality evaluation model based on Bayesian Network, and demonstrates the application methods of Bayesian Network in macro quality evaluation through cases.
