【摘要】：为在航运低迷期使航运企业实现收益最大化,根据航运下行期运力过剩的现状,在现有航线配船模型的基础上,结合现阶段航运下行期的特点,建立混合整数规划模型.首先对集装箱班轮在多条航线上的班轮数量和航次设计构建整数规划模型,将航线配船问题的可行解用染色体形式表示,对航线配船和航次设计进行优化,然后通过MATLAB编程的遗传算法得到该问题的满意解.以某班轮公司为例,对模型和遗传算法的有效性进行验证.结果表明,该方法对于班轮公司根据航运下行期的特点设计合理的航线配船方案具有重要的参考意义.
[Abstract]:In order to maximize the profit of shipping enterprises during the period of shipping downturn, according to the current situation of excess capacity in the downlink period, a mixed integer programming model is established on the basis of the existing shipping route assignment model and the characteristics of the current shipping downlink period. Firstly, the integer programming model is constructed for the number and voyage design of container liner on multiple routes, and the feasible solution of route assignment problem is expressed in the form of chromosome, and the route assignment and voyage design are optimized. Then the satisfactory solution of the problem is obtained by genetic algorithm (GA) programmed by MATLAB. Taking a liner company as an example, the validity of the model and genetic algorithm is verified. The results show that this method has important reference significance for the liner company to design a reasonable route assignment scheme according to the characteristics of the shipping downlink period.
