Site selection method for sea emergency rescue station

Abstract

The invention discloses a site selection method for a sea emergency rescue station. The method comprises the following steps: S1, according to the historical distributed data of sudden accidents in a target sea area, dividing the sea area into different water area units according to the densities of the sudden accidents, and setting the model parameters of respective water area units; S2, creating an emergency rescue station site selection model according to the model parameters in order that the emergency rescue station covers all the water area units of the target sea area, wherein the emergency rescue station site selection model satisfies conditions that the maximum distance between the emergency rescue station and the water area unit possibly generating an accident is minimized, that the total weight that the emergency rescue station covers the water area unit possibly generating an accident is maximized, and that the total weighted distance of the emergency rescue station and the respective water area units is minimized; and S3, solving the emergency rescue station site selection model by using a multi-objective optimization algorithm to obtain an optimal solution set as the optimal site selection position of the emergency rescue station. The site selection method realizes the principle of fairness and efficiency of emergency rescue station site selection, and greatly improves the efficiency and success rate of rescue.

Description

technical field [0001] The invention relates to the technical field of site selection for marine rescue sites, in particular to a site selection method for marine emergency rescue sites. Background technique [0002] During the voyage, maritime accidents are not uncommon due to human factors such as the driver's carelessness on duty, fatigue manipulation of the ship, and environmental factors such as tropical storms. These accidents have caused serious property losses and even casualties, and may also cause irreparable pollution to the environment, which has greatly damaged the interests of mankind. When these accidents occur, the emergency rescue stations set up near the water area where the accident occurred and the rescue resources allocated are the key to reducing the losses caused by the accident. In waters where accidents may occur, when the number and distribution of emergency rescue stations are properly set and sufficient rescue supplies are configured, the emergen...
