Analysis of aviation human factors based on ATHEANA-STPA hybrid method

Abstract

Due to the lack of systematic analysis methods, the traditional a technique for human error analysis(ATHEANA)does not fully identify unsafe action (UA) and error forcing context (EFC).Therefore, a hybrid method of ATHEANA-STPA (systems-theorctic process analysis) is proposed to analyze aviation human factors.The system control model is constructed based on technique for human error rate prediction(THERP) method to identify UA and its associated causal factors.EFC is constructed according to the correlation of various causal factors.The probability of UA is evaluated based on the basic human error data provided by THERP.The risk control measures are formulated based on the idea of disintegrating EFC.Through the analysis of an aviation safety event,the effectiveness of ATHEANA-STPA method is verified.The results show that the analysis conclusion of proposed ATHEANA-STPA hybrid method can play a more specific guiding role in risk management.
