The invention discloses an in-flight ship safety risk prevention and control efficiency evaluation method and system based on capability entropy. The method comprises the following steps: decomposing a ship safety risk prevention and control system; determining a composition unit of each prevention and control capability index; determining a reference constant of each prevention and control capability index; determining a dimensionless polarization processing value of each prevention and control capability index composition unit; determining an association relationship among composition units in each capability index of the subsystem, and determining a capability feature value representing each prevention and control capability of the subsystem; determining the capability entropy value of each capability index of the subsystem; determining a capability entropy calculation formula of each capability index of the subsystem; determining an efficiency value corresponding to each capability of the subsystem; and calculating the total efficiency value of the in-flight ship safety risk prevention and control. According to the method, the accurate evaluation result of the safety risk prevention and control efficiency, namely the total efficiency value of the sailing ship safety risk prevention and control, can be obtained, so that quantitative evaluation of the safety prevention and control performance and effect of the ship in the sailing state is realized, and the precision requirement of people on modern shipping is met.
Description
technical field [0001] The invention belongs to the technical field of ship safety risk prevention and control effectiveness evaluation, and specifically relates to a safety risk prevention and control efficiency evaluation method and system based on capability entropy. Background technique [0002] The safety risk prevention and control of ships underway belongs to the category of ship navigation safety, including three aspects: material prevention and control, human prevention and control, and technical prevention and control. Accurately grasping the actual state of safety risk prevention and control of ships underway has become an indispensable and important link in the development of modern shipping. Accurate and effective evaluation of the safety risk prevention and control performance and effect of the ship under navigation is of great significance to ensure the safe navigation of the ship. [0003] In the existing technology, qualitative methods are generally used to...
