Application of Risk Index to Risk-Based Decision-Making in Vessel Traffic Service System

摘要

The applications of risk index to risk estimation, risk acceptability, and cost-benefit analysis for planning vessel traffic service (VTS) system were analyzed. An example of Wuhan Port shows that its application is easily implemented and can be helpful in a comprehensive 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.
