Analysis of flight safety risk coupling based on fuzzy sets and complex network

摘要

Analysis of flight safety risk coupling plays an important role to prevent flight accidents. In this paper, a topological analysis based on fuzzy network theory is presented to reveal the complex coupling relationship of interrelated risks in flight safety system. The connotation of flight safety risk coupling is presented, and the integration research of fuzzy sets and complex network is introduced. Based on extracting the key flight accident causation factors, the model to analyze flight safety risk coupling is constructed. Finally, the key risk factors and important interactions are gained by analyzing the structural properties of flight safety risk network. The conclusion is that the proposed method based on fuzzy sets and complex network is helpful to reveal the coupling mechanism of flight safety risk factors, and the network theory-based analysis serves as a powerful complement to classical flight safety risk analysis.
