【摘要】：针对海上应急救援基地规划比较单一的问题,结合渤海海域交通流特征和海上交通事故的统计结果,提出了应急救援基地双覆盖优化模型。综合考虑了渤海海域环境条件和事故发生率的影响,基于地理网格划分方法确定了渤海海域应急事故点,根据港口条件选定了应急救援基地候选点。应用双覆盖模型对渤海海域应急救援基地选址进行了优化分析,利用遗传算法优化求解,得到渤海海域应急救援基地选址的最优布局方案。研究结果表明:提出的应急基地双覆盖模型比现有的选址模型有更好的覆盖效果,且适应度函数值高达0.92,充分证明了模型的有效性。
[Abstract]:In view of the relatively simple planning of the maritime emergency rescue base, combined with the characteristics of the traffic flow in the Bohai Sea and the statistical results of the maritime traffic accidents, A double coverage optimization model for emergency rescue base is proposed. Considering the influence of environment conditions and accident incidence in Bohai Sea area, the emergency point of Bohai Sea area is determined based on the method of geographical grid. According to the port condition, the candidate point of emergency rescue base is selected. The location of emergency rescue base in Bohai Sea area is optimized and analyzed by using double coverage model, and the genetic algorithm is used to optimize the solution. The optimal layout scheme of the emergency rescue base location in Bohai Sea is obtained. The results show that the proposed dual coverage model has better coverage effect than the existing site selection model. The fitness function is as high as 0.92which fully proves the validity of the model.
