Research On Generation Method And Application Of Maritime Search And Rescue Resource Scheme Based On Two-stage Model

Maritime search and rescue emergency response capability is an important guarantee for the safety of life and property at sea,and it is also an important part of the construction of a ‘maritime power’.Research on the generation method of marine search and rescue emergency response resource schemes can help improve China’s marine search and rescue emergency response capabilities.At the same time,it also has a positive effect on improving China’s marine soft power.At present,China’s marine search and rescue emergency process has problems such as low search and rescue efficiency,lack of scientific decision-making and unreasonable use of resources.In response to the above problems,this paper has studied the generation of marine search and rescue resource schemes and designed based on the two-stage mode of maritime search and rescue resource plan generation framework of "initial optimization +real-time optimization ".In the initial optimization stage,this paper aims at maximizing the success rate of search and rescue and maximizing the robustness of the resource plan,taking into account various constraints such as sea conditions,time and the number of resources,and constructing a multi-objective optimization model.In the real-time optimization phase,this paper analyzes and identifies the disturbance events and disturbances during the execution of the initial plan and measures the disturbances from the perspectives of the wrecked personnel,search and rescue personnel,and the emergency command center,furthermore,construct an interference management model.The generation framework of the search and rescue resource scheme mentioned in this article is practical and can assist command staff to carry out search and rescue decisions.This article mainly completed the research work in the following aspects:1.Describe and analyze the problem of generating marine search and rescue resources plan,and construct a resource generation framework based on the two-stage model.This article first clarifies the boundary of the problem of generating marine search and rescue resources plan,and explains and analyzes the relevant core concepts involved,including the definition of search and rescue,search and rescue emergency response process,sea sweeping width and resource schemes.Then,this paper analyzes the dynamic influencing factors in the process of emergency search and rescue at sea,and formalizes the description of the problem of the search and rescue resource plan.Finally,a framework for generating search and rescue resources plan based on the two-stage model was constructed,and the specific research content,methods and processes of each stage were clarified.2.Research on the method of generating initial marine search and rescue resources plan.In the initial optimization stage,this paper focuses on the problem of the generation method of initial marine search and rescue resources plan.First quantifies the problem and abstracts it as an operation planning problem.Then comb the input,output and decision variables of the model to lay the foundation for the construction of the model.Then,based on the search planning theory,considering the search success rate,the width of the sea sweep,and the robustness of the search and rescue resource program,the initial sea search and rescue resource program generation model is constructed,and a series of relationships such as the objective function and constraints involved in the model are clarified.Finally,an improved intelligent optimization algorithm is used to solve the constructed multi-objective programming model.3.Study the generation method of real-time maritime search and rescue resources.In the real-time optimization stage,this paper aims at the problem of real-time marine search and rescue resource generation.First,it analyzes and analyzes the dynamic influencing factors involved in the marine search and rescue emergency response process,that is,classifies the disturbance events and recognizes the disturbance.Then,from the perspectives of wrecked personnel,search and rescue personnel,and search and rescue emergency commanders,etc.,the size of the disturbance generated by the interference event is measured,and an interference management model is constructed to specify the model input,objective function,and constraints.Finally,the corresponding intelligent optimization algorithm is used to solve the model.4.Example research.Using the models and algorithms proposed in this article,an example study is carried out on a specific search and rescue case to verify the effectiveness and feasibility of the models and algorithms presented in this article.
