Research On The Assessment And Control Mechanism For The Risks Of Passengers' Unlawful Behaviors At Airports

In the wake of the economic globalization and rapid development of science and technology, the updating process of modernization has stepped into a brand-new period during which the civil aviation industry has been making a huge contribution to this process. However, due to its intrinsic nature of sociality and speciality, its safety management and security operation may be disrupted by some disharmony and incompatible factors deriving from the society while it serves the interest of social development. But when the amount of accumulating interaction generated by those unpleasant factors mounts up to some degree which may lead to some unlawful activities conducted by the passengers and it could impose a detrimental influence on the safety management and security operation within the airport complex. Many assaulting cases involved passengers and staff members working at the airport were reported by the domestic media last year. According to the news, the main causes of these physical conflicts and other incidents were flight delay and defects in the rules and regulations. The international aviation suffered a lot last year as well. And many aviation security experts suspected that more than half of these reported incidents were caused by the slack of security check procedure and the loophole of security system. Based on these facts, it is beneficial to establish a practical and scientific early-warning mechanism against unlawful activities conducted by the passengers within the airport premise. With this mechanism, the security status within the airport will be enhanced. Moreover, it can prevent disruptive and destructive actions against the aviation transportation process from the terrorists and criminals in advance. Therefore, it has a significant practice.This thesis starts with the feature description of unlawful activities committed in the airport and its regular patterns, followed by its affecting influences and causation process. This thesis analyzes a number of factors which could affect those unlawful activities conducted by the passengers from four perspectives, namely human, machine, circumst2 ance and management. Then the security risk assessment indicator system is formed by use of AHP and grey fuzzy evaluation. After that, some aviation security experts is invited to give a certain civil airport a security assessment according to the indicator system respectively before using the gray model to work out a numeral outcome. Finally, the whole risk level is appraised by evaluating this digit.The author manages to put forward early-warning mechanism against unlawful activities within airport complex based on the risk assessment outcome and safety management and security deployment operated in the US and Euro airport after carrying out the risk assessment at airport. This mechanism focuses on building a platform used for collecting and sharing intelligence, and risk-based security policy. It advocates to set different security procedure in line with different risk level of passengers which means the security department should sort the passengers into different groups in the light of their risk level and security profile. This method can increase the working efficiency by allocating the most security resources upon the passengers and luggage. In addition, the establishment of platform used for collecting and sharing intelligence and information about aviation security not only will benefit the security management in the aviation industry, but also will serve the interest of other transportation system such as railway security, highway security and etc. If this concept is realized ultimately, the systematic mechanism would make a huge contribution to the civil transportation security management as a whole.
