A Quantitative Risk Assessment Approach Based on Safety Performance

Safety is the most important thing for civil aviation organization's survival and development. Firstly, the safety performance-related requirements from the International Civil Aviation Organization is introduced. The latest research progress of safety performance management from academic and industry is reviewed. Secondly, the safety performance management life cycle which combines the Plan, Do, Check, and Act management approach is presented. There are Plan phase, Do phase, Check phase, and Act phase in the safety performance management life cycle. For each phase, steps used to implement safety performance management are discussed. Thirdly, a quantitative risk assessment approach is proposed based on the established safety performance indicator system of a civil aviation organization and its departments. Heinrich's Law is used as a baseline to assign the severity coefficients for different types of safety performance indicators by considering the standard “Civil aircraft incident” published in 2018. Severity scores are used to reflect the differences among safety performance indicators belong to the same type. Finally, a case study of an aviation fuel company is demonstrated to verify the feasibility, effectiveness and efficiency of the proposed risk assessment approach. It is found that the assessment results for the aviation fuel company and its six departments are in accordance with the actual operation situation of the aviation fuel company.
