abstract

A method of safety performance measurement is proposed to monitor the safety management process of civil aviation unit (CAU) with a series of safety performance indicators (SPIs). All these SPIs are arranged in a three-level model based on the analytic hierarchy process (AHP) and Delphi method, called the DAHP model, which takes full advantage of the expert knowledge and quantitative calculation. The weight of each SPI is estimated by the DAHP model, while its score is monitored and measured quantitatively with the two values of the standard deviation and average values of the preceding historical data points. The proposed method was tested successfully on the real data of a regional CAU in China, reflecting the CAU's safety management state immediately and quantitatively.

5. Conclusion

The theory of SMS has been the guidance of the CAU safety management in recent years. With the promotion of SMS, the simple meeting of regulatory safety requirements should be changed to quantitative safety performance monitoring and measurement. In this paper, a specific method is proposed for safety performance measurement based on the DAHP model. Some conclusions are given as follows: 1) The combination of AHP and Delphi method takes full advantage of the expert knowledge and mathematical model. 2) The safety performance measurement is more feasible and quantitative with the monitoring of the SPIs of work completion rate and equipment intact rate. 3) It is more reasonable to monitor the SPIs under the standards of the target and alert level monthly than the subjective judgments of experts at the end of the year. 4) The SPIs, weights, score deduction standards and score division standard proposed in this paper are for reference only. The civil aviation units should make their own SPI system and management process according to their specific situations.
