在考虑多等级蓄意攻击的情况下,研究第三方物流(3PL)可靠性网络设计问题.建立问题的多层优化模型:3PL网络设计模型在可靠性约束下通过开设不同安全等级的物流设施来最小化总物流成本;蓄意攻击模型选择不同等级的攻击策略使网络的服务水平最低;网络流决策模型可最大化网络受攻击后的服务能力.根据问题模型的特点,设计改进两层人工蜂群(ABC)算法,上层ABC算法求解3PL网络设计问题,下层ABC算法求解蓄意攻击优化问题.网络流决策问题则通过网络流算法进行求解.最后,通过仿真实验来验证所提出模型的合理性及算法的有效性.
Considering the multi-level deliberate attack, this paper studies the problem of the reliability network design of 3PL.People build the multi-layer optimization model of the problem: the 3PL network design model has the smallest security level through the establishment of logistics facilities under the reliability constraints The total logistics cost; intentional attack model to choose different levels of attack strategy to make the network service level minimum; network flow decision-making model can maximize the network after attacked service capabilities.According to the characteristics of the problem model, design and improve two layers of artificial bee ABC algorithm, the upper ABC algorithm to solve the problem of 3PL network design, the lower ABC algorithm to solve the deliberate attack optimization problem.Network flow decision-making problem is solved by the network flow algorithm.Finally, through simulation experiments to verify the rationality of the proposed model and the algorithm Effectiveness.
