Abstract

Introduction: With the rapid development of the civil aviation industry and the growth in the number of airline employees, some unsafe and dishonest events occur frequently. These behaviors affect the flight safety seriously. Method: First of all, the connotation of safety integrity was defined based on literature analysis. According to the connotation, relevant typical cases were collected. Through the use of Field Theory for case analysis, the main factors that affect safety integrity were identified. By using DEMATEL-G1 and DEMATEL-ISM methods, the relationships between these factors were analyzed quantitatively, and the internal effect paths of the influencing factors were established. Results: There are sixteen major factors that affect the safety integrity of airline employees. Six of them are crucial. The effect path system of all factors can be divided into four layers: the first layer is the appearance layer, including eight factors, which are the direct causes affecting airline employee’s safety integrity; the second layer is the middle layer; the third and the fourth layers are the root layers, including  four factors, which are the deep causes affecting airline employee’s safety integrity. It is also worth noticing that “incentive and penalty system of safety integrity”, “supervision of government and company”,“ stability and efficiency of the organization”,“ emphasis and example of leaders on safety integrity” are not only crucial factors, but also the root layers of the structural model. They are the most important factors.
