民用运输机场安检系统风险影响因素研究

Research on influencing factors for risk of security inspection system in civil transportation airport

为提高民用运输机场安检系统风险管理水平,提出机场安检系统风险辨识模型,基于流程分析的方法确定机场安检的关键岗位,对各关键岗位中的不安全事件运用假设故障类型分析得出各岗位的风险因素;从人-机-环-管对风险因素进行归纳总结,建立民用运输机场安检系统风险影响因素集。提出DEMATEL-ISM风险集成模型分析安检系统风险影响因素的相互关系及层次结构。结果表明:通过模型的影响度计算得出,社会局势对机场安检系统风险影响最大、安检员的服务态度最易受其他因素的影响;通过模型的多层递阶解释结构计算得出,社会局势、安检作业环境、安检员薪酬制度和晋升制度是机场安检系统风险的根源影响因素。集成模型有效分析机场安检系统风险影响因素及其重要性和层次结构,可为机场安检系统风险的有效管理提供依据。

In order to improve the risk management level of security inspection system in the civil transportation airport,a risk identification model of airport security inspection system was put forward.The key positions of airport security inspection were obtained on the basis of the procedure,and the risk factors of each position were obtained by using the hypothetical failure mode analysis on the unsafe events in each key position.The risk factors were summarized from the man-machine-environment-management,and a set of influencing factors for the risk of security inspection system in the civil transportation airport was established.A risk integration model combined DEMATEL and ISM was proposed to analyze the interrelationship and hierarchical structure of risk influencing factors of the security inspection system.The results showed that social situation had the greatest influence on the risk of airport security inspection system and service attitude of security inspectors was most easily affected by other factors through the calculations of DEMATEL,and social situation,working environment of security inspection,salary and promotion system of security inspectors were the root influencing factors for the risk of airport security inspection system through the analysis of ISM.The integration model could effectively analyze the risk influencing factors of airport security inspection system and their importance and hierarchical structure,which can provide basis for the effective management on the risk of airport security inspection system.
