Risk assessment modeling in aviation safety management

Abstract

Safety risk management is important in aviation. This paper develops a quantitative model for assessing aviation safety risk factors as a means of increasing the effectiveness of safety risk management system by integrating the fuzzy linguistic scale method, failure mode, effects and criticality analysis principle, and as low as reasonably practicable approach. The model is developed by evaluating all related estimation factors based on their importance, how hazardous they are, their detectability, probability, criticality, and frequency. An empirical study demonstrates the modeling process.
