摘　　要：针对我国南海群岛海域广阔,运输距离较长的特点,建立了海空协同运输背景下综合确定海运中心岛选址、码头建设、船型及飞机机型配备、海空航线设置、仓储规模的物流网络优化模型。结合所建模型特点,提出了在局部搜索染色体选择、邻域算子自适应选择以及在适应度函数计算中融入记忆库搜索等方面进行改进的变邻域搜索文化基因算法,有效提高了算法的求解效率。最后,以我国的南海西沙和南沙群岛物流网络优化为例,验证了本文模型和算法的有效性。研究成果可为边远群岛海空协同物流网络的构建提供了新思路和新方法,可为我国南海群岛建设海空协同运输的物流网络建设提供技术支撑,对于加强南海海疆建设具有重要的理论意义和应用价值。As the South China Sea Islands are far from the mainland,many of the daily production and living materials need to be supplied from the mainland,and the seafood from the islands needs to be transported back to the mainland,so the establishment of an efficient logistics network is an important part of the construction of the South China Sea.In recent years,the Chinese government has expanded and built a few seaports and airports in the Xisha and Nansha Islands in the South China Sea to meet the production and living needs of the islanders.The construction of these transport facilities has laid a very favorable foundation for building a logistics network.In this context,the construction and optimization of a logistics network for sea-and-air collaborative transportation is of great theoretical significance and application value to further enhance the economic development capacity of the islands,strengthen the production capacity and quality of life of local people,and defend China’s sovereignty over the South China Sea.This paper establishes a logistics network optimization model with the minimum total logistics cost as the optimization goal,and comprehensively determines the site selection of marine center islands,the number and scale for construction berths,the types and quantity of transport ships and aircraft,shipping and air route configurations,storage capacity of warehouse and other issues,focusing on solving the location-inventory-route optimization problem of the logistics system under the collaborative transportation of sea and air transport modes.The model needs to optimize the logistics system for the daily needs of islanders under normal circumstances and needs to adapt to the air transport of emergency supplies under special circumstances such as typhoons.Based on the characteristics of the proposed model,we propose a memetic algorithm(MA),which combines a variable neighborhood search(VNS).Besides,some improvements are made in the selection of local search chromosome,the adaptive selection of neighb
