An example of Wuhan Port shows that its application is easily implemented and can be helpful in a comprcbensive and scientific decision-making. Especially aiming to the difficult problems with respect to risk prediction, risk acceptability and cost-benefit assessment, this article put forward some new solutions based on risk-index, such as the trendline estimation, ALARP （as low as reasonably practicable） matrix and weighted cost-benefit analysis, with a fairly good operability and comparability.展开更多

Marine traffic simulations are carried out in a virtual port area with various arrangements and conditions. Calculations of stress values and traffic volume criteria are illustrated. The simulation results provide a valuable hint for safety management of vessel traffic. The model provides quantitative information and helps administrators in decision making to achieve desired safety level and improve the efficiency of vessel traffic in ports and waterways.展开更多
