Failure Analysis of Aviation Fuel Storage,Transportation and Refueling Control System Based on Bow-Bayesian Network
The aviation fuel storage,transportation and refueling control system is an important control system in the civil aviation industry,and preventing the risk of failure is the basis of aviation safety.This article focuses on the control system of aviation fuel storage,transportation and refueling,and proposes a failure analysis method combining bow and Bayesian methods.The failure analysis model starts from a specific business perspective and analyzes the intermediate events of the aviation fuel storage,transportation and refueling control system failure,including storage and transportation failures,fuel supply failures and fuel detection failures.Then,from the perspectives of functional safety and network security,it analyzes the factors that cause subevents of intermediate events.By using logical mapping,the bow model is transformed into a bow Bayesian model to further analyze the probability of subevents and top events.In addition,the failure analysis model proposed in this article mainly considers different possible accident consequences after failure of different protective measures.Finally,by applying the aviation fuel storage,transportation and refueling control system,the scientificity and feasibility of the model in system failure risk analysis are verified.
