Vegetable Safety Risk Early warning Model Based on Fault Tree

This paper introduced the fault tree analysis method and its application, analyses various factors of vegetable safety status and safety problems caused by vegetables, establishes the fault tree of the vegetable safety, and for this fault tree do some qualitative and quantitative analysis, combines the theory of risk analysis, and then establish vegetable safety risk early-warning model based on fault tree analysis. This model aims to predict severity of the hazards and take measures to reduce the harm may occur. In this context, this not only broadens the application domain of fault tree analysis, but also provides a reference for the safety of vegetables in the future.
