Study On Ship Domain Model And Trafic Capacity Based On Human Factors

Along with the development of the shipping economy, a large number of ships frequently active in port and waterway and their adjacent waters,which has greatly increased the density of navigable waters, resulting in ship traffic volume increasing, and increasingly busy waterway vessel traffic. Therefore, the channel capacity requirement also is increasing day by day. On the premise of ensuring the safety of shipping, which will be a problem to be solved is further excavation of channel capacity. Among a lot of factors affect the channel capacity, ship domain is a very important factor, however, the current of the ship in the field of research is mainly limited to speed, the captain, encounter situations, such as easy access to information, for the ship maneuvering performance, uncertainty factors and rarely consider such as human factors. This article mainly research dynamic four-element ship domain model based on human factors and waterway capacity evaluation.Firstly, a fast and exact online self-organizing fuzzy neural network based on (FAOS-PFNN) ship domain model identification approach is proposed in this paper. The method effectively established reference input variables and the ship in the field of non-linear relation between the shape and size of the output variable. Furthermore, through FAOS-PFNN method, the separation of the three fuzzy neural network was adopted to realize the model of ship domain model of multiple input/output system identification. In addition, in this paper, combining the theory of ship motion, the existing four-element ship domain model, on the basis of fully considering the different the dynamic control performance and the drivers of human factors to influence in the field of a ship, thus put forward four-element ship fields of dynamic model based on human factors. Effectively combines the model ship subsystem and human factor system, give full consideration to the ship maneuvering performance and ship the driver of the business skill levels, physiological, psychological state and navigation environment such as the influence of man-made factors, the dynamic ship modeling in the field of intelligent. At the same time, in this paper, the dynamic four-element ship domain model based on human factors are applied to the Mariner, Esso Osaka Container and Tanker three classic type of ship, the simulation results verify the rationality and effectiveness of the field of the ship model.Secondly, the dynamic four-element four-element ship domain model based human factors has been proposed firstly in this article, which integrated the ship maneuvering performance and human factors effectively. At the same time, the fuzzy theory to the data processing of the questionnaire, in order to obtain one for parameters, thus put forward considering human factors of waterway capacity calculation method. it could effectively mining capacity and improve the capacity by using this method.Finally, evaluation model of channel capacity has been established based on human factors in the paper. Yoon Gongju of the Yangtze River waterway and Laotieshan channel has been taken as two different congested waters research object. Actual calculated the waterway navigation capability. The experimental results show that using the method of capacity than traditional method based on Fujii ellipse field of ship has large improvement. And through to the old iron mountain channel capacity calculation, the next five years and 10 years of old iron mountain segment of broadening the planning is adviced, which offer reference for water traffic planning and management to navigation for related department assessment...
