An Integrated Fuzzy Evaluation of Level of Safety Culture at Civil Airports

Evaluation of the level of safety culture for civil airports is considered an effective approach to maintain the sustainable and safe development of civil aviation in China.In order to propose an evaluation system of safety culture of civil airports,a systematic analysis is firstly introduced;then by considering the accidents and features of civil airports and referring the Enterprise Safety Culture Construction Guide and Enterprise Safety Culture Evaluation Criteria ,and other civil aviation regulations,the evaluation measures of safety culture at civil airports are determined.A survey among staffs at airport operational departments is carried out.The responses from inspectors in airports and experts of safety culture are considered.To optimize the evaluation systems and determine the weights of all measurements,the Analytic Network Process method available in the software package of Super Decisions is used.Meanwhile,a case study of one civil airport in North China by using an integrated fuzzy evaluation is introduced.The evaluation results indicated that the score of safety culture in this airport is 77.7,which is at the level of active safety [70-85).The results of this study demon-strate that attitude and understanding to the safety among the airport staff is the core of safety culture.The evaluation model proposed in this study is of a great value and could be further implemented for evaluating safety culture in civil air-ports.
