摘要

摘要要求导航性能（RNP）程序在飞机导航中的使用一直在增加，因为它可以更好地优化日益拥堵的空域。本工作旨在研究功能共振分析方法（FRAM）与贝叶斯置信网络（BBN）提供的定量分析相结合的应用，以证明基于RNP程序的复杂导航系统中功能的现有可变性，特别是当飞机接近机场时（进近阶段）。因此，可以分析所研究系统中发生的变化，BBN通过允许对被认为对RNP进近程序的执行最重要的功能进行定量解释来补充研究。

Safety analysis of RNP approach procedure using fusion of FRAM model and Bayesian belief network

Abstract The use of the required navigation performance (RNP) procedure has been increasing for aircraft navigation, since it allows for better optimisation of the airspace, which is increasingly congested. The present work aims to investigate the application of the functional resonance analysis method (FRAM), combined with the quantitative analysis provided by the Bayesian belief network (BBN), to demonstrate the existing variability in functions that are part of the complex navigation system based on the RNP procedure, specifically when the aircraft approaches the airport (approach phase). As a result, it is possible to analyse the variability that occurs in the studied system and the BBN complemented the study by allowing a quantitative interpretation of the functions considered most important for the execution of an RNP approach procedure.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
