班轮运输船队规划的改进模型

摘要

为了提高复杂情况下船队发展战略优化方法的实用性和客观性,对班轮运输船队规划问题进行了新的探讨.根据航运市场环境的需要,建立了同一航线上配置多种船型的班轮船队规划数学模型.考虑到模型的求解复杂性,引入关键航段的概念对原模型进行了改进.以某航运公司的班轮船队为例进行仿真实验,将改进后的模型与传统班轮船队规划模型进行比较.结果表明,改进模型科学、可行,满足航运市场环境和班轮运输组织的实际需要.%In order to promote the studies in the area of optimizing fleet development strategy,liner fleet planning problem was discussed.A liner fleet planning model was presented based on the variety types of ships are deployed on the same route to meet the needs of the shipping market.Taking the complexity of solving the model into account,the original model was improved by introducing the concept of key sectors.By using a shipping enterprise as an example,the improved model was compared with the traditional liner fleet planning model.The results indicate that the model is scientific and feasible,it well meets shipping market and the practical needs of the liner shipping community,and thus it provides a new method for liner fleet planning.
