考虑货主选择惯性的班轮运输系统优化模型

Container shipping system design considering the shipper's choice inertia

基于需求季节波动背景,在考虑货主选择惯性的条件下,以班轮公司收益最大为目标,构建远洋集装箱运输系统优化模型,优化航线网路结构、航线配船,基于需求波动与货主选择惯性特征优化航线网络的调整方案与舱位配置.基于遗传算法提出一种遗传线性规划混合算法.计算结果表明,优化模型能够在考虑运输服务稳定性的要求下,优化班轮运输系统,在提高班轮公司收益的同时,提升货主的服务体验.最后通过分析计算结果,证明了模型的实际意义与可靠性.

This paper introduces an optimization model（ COSDM） of Container Ocean-transportation System with the objective of maximizing the profit of a liner company,while taking the seasonal changes of transportation demands and choice inertia of shippers into consideration. COSDM can optimize shipping network design and fleet deployment simultaneously. It also optimizes the plans for shipping network adjustment and for distrusting slots in ships based on the fluctuant demand and the characteristics of the shippers’ chosen inertia. To solve COSDM,a heuristic algorithm（ ACOSP） is put forward by combining Genetic Algorithm and Linear Programming. The experimental results show that COSDM can give an optimized design of the system in consideration of the stability of transporting services. The proposed model also improves the user experiences of the shippers while increasing the profit of the liner company.
