Considering the problems of randomness and fuzziness in evaluating indexes from maritime search and rescue response capability system, a novel method based on subjective-objective attribute weights integrated and center normal grey cloud method was presented. Firstly, cloud theory was introduced to transform the uncertainty of factors into quantitative digital features, to achieve the qualitative indicators of quantitative processing. Secondly, the improved analytic hierarchy process(IAHP) and c...

The paper concerns parameter identification of a responding ship motion model for a full-scale ship under the framework of system identification (SI) principles. Several groups of full-scale maneuvering experiments have been implemented to collect research data. A linear responding ship motion model is selected for analysis, and specifically identification of two parameters of the model becomes the research topic. Based on the error criterion in SI theory, a Particle Swarm optimization (PSO) bas...

ABSTRACTIn this paper, a risk cloud model (RCM) based on cloud model theory is proposed for evaluating risks in the nautical navigational environment (NNEt). To validate the method, the proposed strategy is applied to a risk evaluation of NNEt of the waters around the Hangzhou Bay Sea-Crossing Bridge and the results are compared with those of a conventional fuzzy theory-based evaluation approach. The results show that risk evaluations based on the proposed RCM are robust, can accommodate uncerta...

In order to set up a mathematical model suitable for nautical navigational environment risk evaluation and systematically master the navigational environment risk characteristics of the Qiongzhou Strait in a quantitative way, a risk assessment model with approach steps is set up based on the grey fixed weight cluster (GFWC). The evaluation index system is structured scientifically through both literature review and expert investigation. The relative weight of each index is designed to be obtaine...

To find out solutions to automatic collision avoidance with multiple targets, which would promote ship automation and intelligence, the basic principle of velocity obstacle theory was applied for the own ship to avoid collision with multiple moving or static targets. The principle of ship collision avoidance was analyzed and solution of demanded course for the own ship to navigation with at current to avoid collision was proposed based on velocity obstacle. With kinematics equations of own ship ...

Large-scale maritime simulation platform faces the contradiction among timeliness, accuracy and integrity in the data collection, storage, analysis and exploitation, due to the features of maritime big data, such as large-volume, multi-source heterogeneity, abruptness and high noise. With this background, in order to deal with the complexity and imperfectness of maritime big data, this paper employs the networked data as the analysis object with more emphasis on the indirect relevance and in-dep...

The study on marine accidents has been a keen subject in ocean engineering for long. This paper develops an HFACS-EI Framework based on the original HFACS Framework. The framework is further combined with Cognitive Map (CM) in marine accident evolution analysis which is divided into four stages. A hybrid accident analysis approach combining HFACS-EI Framework and CM not only provides classification of human factors under six levels, but also judges if there is a positive relation between every t...
