Developing Risk Reduction Strategies of Typhoon Disaster for Ports from the Perspective of Resilience

With the deepening of economic globalization, the strategic significance of ports is rising. However, ports face various risks and challenges from both internal and external sources. This paper introduces the resilience theory into the port safety risk management, and explores the port resilience change and the corresponding risk response mechanism effect when facing typhoon disaster. The definition and characteristics of port safety resilience are analyzed, and a triangular model of port safety resilience is constructed. Taking the container supply capacity as the performance index, using the functional level function to generate the port system resilience curve, according to the curve change characteristics, the safety resilience of the port system is analyzed and evaluated in four stages. Combined with the basic conditions of the target port and the operating data of mechanical equipment, the change of the safety resilience of the port logistics risk system after the typhoon attack was simulated. The joint risk coping strategies were developed from the aspects of single port and port cluster respectively, and the effects of different strategies on port safety resilience were evaluated under the influence of typhoon disaster. This paper applies the tenacity theory to the research of port system safety management, and realizes the quantitative evaluation and assessment of port tenacity under typhoon disaster by means of risk modeling and simulation, which provides reference for port disaster prevention and mitigation.
