Entropy-Based Model for Aerodromes Safety Risk Assessment to Implement Safety Management Systems

Abstract


 
 
 All certified Aerodromes require to implement Safety Management System (SMS) from November 2005 according to the International Civil Aviation Organization (ICAO) requirements. Nowadays safety risk assessment in aerodromes with main operational scopes has been a critical issue in the aviation industry. The current SMS model is no more sufficient to comply with this complexity and cover all aspects of aerodrome factors quantitatively. A new model for aerodrome safety risk assessment to evaluate Aerodrome’s safety riskbased on the Entropy method is developed in this research. In this new method, critical criteria and their sub-criteria are developed and then assess the safety risk. One Aerodromes (as a case study) is considered and the weight of criteria and sub-criteria are measured based on Entropy technique and aerodrome safety performance is assessed. The first phase was the weight measurement of criteria by the Entropy method, and then evaluate related safety performance. Based on the safety risk assessment result, the aviation experts were interviewed to verify the result, which supported our research outcomes. The result of this research should guide aviation SMS experts to take proper safety mitigations to prevent any safety events in aerodromes.
