Design and Implementation of Maritime Rescue Aircraft Decision Support System for the Middle and Far Seas of the South China Sea

Aiming at the problems of maritime rescue aircraft application decision in the middle and far seas of the South China Sea, such as insufficient of the emergency plan, low efficiency of decision making and poor real-time and implementability of rescue plan generating etc, this paper proposes a design method of maritime rescue decision system for aircraft based on emergency plan and scenario analysis. According to the application conditions of our country's maritime rescue aircrafts, combined with the key features of classic maritime accidents and the South China Sea, this paper completes the construction of the system and realizes the real-time and efficient application decision making of maritime rescue aircraft in middle and far seas. This method uses the information extraction technology based on large language model to extract the key features of the accident from the history accdents and emergency plans, forms the meta scenarios, and constructs the meta scenarios base based on accident types and levels. When a maritime accident occers, based on dynamic scenario analysis and SBERT model, maritime accidents are classified and graded. Then the method selects the meta scenario set that matches the current accident needs from the meta scenario base, and constructs action instructions through instruction templates. It uses the task planning technology to optimize and adjust the priority of rescue instructions, and finally generates a feasible real-time rescue plan. Maritime rescue aircraft decision support system fully utilizes the standard of the emergency plans and the instantaneity of the scenario analysis method, generates an optimized rescue plan that is closely related to the maritime accident information. The system further improves the accuracy, scientific and intelligent level of the maritime rescue aircraft application in the maritime rescue decision making process.
