Research on Yangtze River waterway transportation safety evaluation model based on fuzzy logic theory

Waterway transportation accidents may cause great economic losses, casualties and environmental pollution. Traditional comprehensive index method is used to conduct safety assessment with fixed values, and can´t reflect the randomness and uncertainty of risk. This paper analyzes several typical factors influencing the Yangtze River waterway transportation safety to identify four indexes for waterway transportation safety evaluation, and then the waterway transportation safety evaluation model is established through the method of fuzzy logic to analyze the Yangtze River waterway transportation accident data from 2002 to 2011. With the accurate evaluation results, this model is reliable. This study can be used to improve the management of Maritime Safety Administration.
