Abstract:

Addressing the issue of uncertainty quantification in the evaluation of aviation support activity maintenance personnel behavior, this study establishes an evaluation framework for behavioral uncertainty of maintenance personnel based on uncertainty theory, clarifying the evaluation models for perception class, decision-making class, and execution class behaviors. Based on the characteristics of human-machine interaction in aviation support activities, a scenario decomposition method and its uncertainty propagation calculation method based on the uncertain random Bow-tie model are proposed. Accident analysis results of the weapon mounting process of combat aircraft indicates adding safety devices to the internal weapons bay doors and arranging for maintenance personnel to observe from outside the bay can reduce the probability of catastrophic accidents. The proposed method is effective in assessing human-factors risk of aviation support.

Key words: human error, belief reliability, human reliability, risk assessment, uncertainty theory
