Control Mode And Failure Mechanisms Of Stable Condition For The Human-Ship System

As ships quantity increasing, tonnage enlarging and the speed enhancing, there is a higher request for the marine traffic safety, and we must do further studies for accident's occurrence mechanisms and the control mode. The paper has done the systemic research to failure mechanisms and the control mode of the ships navigation's stable condition with safety system engineering logical thinking and the angle of person, ship and environmental effect. The ships security evaluation and the management information system has been made on the base of the theory achievement, all the work done in this paper provided the theory basis and the practice safeguard to prevent and reduce the marine traffic accident.With the statistical analysis of ship safety accidents ,this paper carries on the analysis on degree of correlation of the collision accident disaster-causing , has traced the root causes of the human failure in the ship maneuvering and has established organism function Markov condition chain of ocean seafares which has been simulated , carries on the analysis on person's behavior process expiration with engineering neuron, has established the time-variable behavior reliability computation model, proposes the concept of crew seaworthiness and the computation model and has carried on the analysis to the renewal pattern and the maintenance mode of the seaworthiness and has established seaworthiness maintenance model on the base of the circuitry, the paper has also carried on the simulation to crew's seaworthy response output.From the angle of coordination control between person and ship, this paper carries on the appraisal to the rational distribution of ships man-machine function with the AHP law and conducts the research on safety control pattern of the ocean navigation, navigation in recent sea area and navigation in the post oral region; In the control of human-ship stable condition, this paper establishes the person ship integration closed-loop control mathematical model according to transfer function mathematical model of ships controled, and has carried on the simulation analysis to its output state. To further analyze on human's behavior output procedure, this paper has also carried on the simulation analysis to best setting of human quadratic form.In view of the important effects of device status to ship maneuverability, the paper has carried on the computation with the state space coupling theory to the ships man-machine system breakdown transition probability and has established the optimized model for the equipment spare parts and the equipment service in combination of the Baltic Sea freight index on the base of the reliability and the efficiency, and has carried on the example confirmation.The concept of ships security entropy and the appraisal mathematical model has been defined in this paper. With the current information technology, from four information sources that the crew, the ships, the environment and manage. This paper also established the ships dynamic navigation safety control information system for the ships manipulator and the shipping managers to take the associated measures to reduce the failure probability of the human- ship system stable condition.
