Construction and Validation of Safety Risk Evaluation Model for Operating Jobs in Airport

The object is researching the methods and techniques of safety risk evaluation in airport and developing a useful tool, for supporting the implementation of aviation safety management system in China. Based on SHEL Model and China Civil Aviation Regulations established the evaluation model. The model involved personnel, equipment, procedures and environment. The model had three hierarchies and included 75 indexes. Raw data were collected by questionnaires that came from the airport managers and operators. It used the Analytic Hierarchy Process and triangular fuzzy numbers to establish the weight value of the safety risk evaluation model of pivotal operating jobs in civil airport, and then verified an example. The example displayed that safety integrated risk index (SIRI) of the operation commanders and the special vehicle operators were 40.7 and 40.4. The SIRI values of the two jobs were higher, and the result was consistent with the current situation. The results showed that SIRI had certain objectivity and representation. The model is valid. The evaluation model can be more comprehensive and accurate status of safety performance of pivotal operating jobs in the airport. All weights were acceptable.
