考虑集装箱流恢复的班轮运输船期恢复模型

为降低干扰事件对班轮运输服务的不良影响,本文研究了班轮运输中的船期干扰恢复问题.涉及4种船期恢复策略:调整航速、缩短在港时间、交换港口挂靠顺序和取消港口挂靠.当采取"取消港口挂靠"策略时,考虑集装箱流恢复问题,建立了船期恢复问题的混合整数非线性规划数学模型,并采用LINGO软件和遗传算法分别对模型进行求解.利用来自中远集装箱公司的实际案例,对模型和求解方法进行了验证,结果表明,所提模型和求解方法是正确有效的,能够为班轮公司提供科学的干扰管理决策支持.

A Vessel Schedule Recovery Model Considering Container Flow Recovery in Liner Shipping

To reduce the adverse effect of disruption event brings to liner shipping service, this paper investigates the Vessel Schedule Recovery Problem (VSRP) in liner shipping. Four vessel schedule recover strategies are involved in this paper: speed adjustment, shorten port time, swap order of calls and omitting a port call. Consider the container flow recovery problem when the strategy omitting a port call is taken. A mixed integer nonlinear programming mathematical model is presented for the VSRP. The proposed model is solved by the software LINGO and genetic algorithm, respectively. The model and the solution approach are verified by investigating a real-life case from COSCO Container Lines. The result shows that the model and the solution approach are valid and effective which can supply scientific decision support of disruption management for liner companies.
