Causing mechanism analysis of human factors in the marine safety management based on the entropy

The unsafe behavior has been generally recognized as the main reason of marine accidents. How to control and reduce the accident in the maritime safety management resulted from human factors is a prompt problem to be solved. This article analyzes the marine safety management system from the viewpoint of safety system engineering, and divides the human factors into personal factors and organizational ones, and the vulnerability theory of complex system based on the entropy is applied to analyze the cause mechanism of human factors and a causing mechanism model of human factors is established. It is concluded that the vulnerability relationships among vulnerability elements including man, machine and environment subsystem in ship safety management system is completely vulnerability relations, namely the collapse of any subsystem will affect the other subsystems.
