Abstract
Aiming at the systemic, ambiguity and randomness characteristics of the aircraft's heavy landing risk, this paper starts from the system perspective and proposes a risk assessment method based on the Best- Worst method (BWM) and cloud model. Aiming at the ambiguity and randomness of the information in the risk assessment, the cloud model is used to describe the language. In view of the difference in weights, combining BWM and cloud models for weighting. Finally, an example is given to ver ify the reasonableness and effectiveness of the model.
Highlights
Aircraft heavy landing risk refers to unsafe incidents that occur during the landing phase when the load exceeds the limit when the aircraft touches the ground, which may lead to accidents that cause damage to the aircraft body structure, and even serious flight accidents that cause damage to the aircraft
For heavy landing risk assessment, there are still the following problems: 1) Data processing lacks systematic and technical statistical analysis and research; 2) it is difficult to get rid of the limitations of the traditional expert empirical qualitative risk analysis and assessment model; 3) insufficient consideration of the large amount of ambiguity, randomness and cognitive uncertainty in the evaluation process.This paper proposes a risk assessment method based on BestWorst method (BWM) and cloud model
Randomness and uncertainty in the heavy landing risk, this paper proposes a risk assessment method based on BWM and cloud model, and combines examples to illustrate
