【摘要】：船队规划是科学、合理配置航运企业有限资源的重要决策,它不仅关系到企业未来的竞争力,同时也是决定航运企业能否长期生存、发展的关键问题。据统计,班轮运输收入占整个航运业总收入的50%以上,因此,班轮船队规划问题就显得尤为重要。科学地进行班轮船队规划,使船队始终保持合理的规模和结构,从而加强自身竞争力,更好地为客户提供优质服务,这对班轮经营者意义重大。本文在力求理论指导实际、增强实用性的基础上,充分分析班轮运输组织方式的特征和规律,展开对多港口挂靠、货物直达运输航线形式的班轮船队规划问题的研究,综合考虑了预测的货运需求与运价、船队现状、单船最大载货量、新船造价、航线最小发船班次要求及决策者对研究期末船队实物账面价值的重视程度等影响班轮船队规划的主要因素,在构建班轮航线配船数学模型的基础上,以追求研究期内班轮船队利润折现值最大为目标,进而构建了班轮船队规划数学优化模型。进一步,为了解决模型在实际应用中的难题,运用Visual Basic和LINGO混合编程技术,设计开发了班轮船队规划应用软件(LFPDSS)。软件操作简单,可以实现友好的人机交互,能够根据用户输入的初始已知数据,求解出研究期内船队发展最优方案及相应的航线配船方案,为用户提供快速、准确的参考数据。最后,本文通过某班轮公司2015-2019年船队规划案例,验证了模型的有效性,并通过反复测试表明,软件运行稳定,计算结果正确,具有很强的实用性,可以为班轮运输组织者提供良好的船队规划决策辅助支持。
[Abstract]:Fleet planning is an important decision of scientific and rational allocation of limited resources of shipping enterprises. It is not only related to the future competitiveness of enterprises, but also a key issue to determine the long-term survival and development of shipping enterprises. According to statistics. Liner shipping revenue accounts for more than 50% of the total revenue of the shipping industry, so it is particularly important to plan the liner fleet. Scientific planning of the liner fleet makes the fleet always maintain a reasonable size and structure. In order to strengthen their own competitiveness, better to provide customers with quality services, which is of great significance to liner operators. This paper fully analyzes the characteristics and rules of liner transportation organization mode, and studies the planning of liner fleet in the form of multi-port link and direct freight transportation route, and comprehensively considers the forecast freight demand and freight rate. The main factors that affect the planning of liner fleet are the status quo of fleet, the maximum loading capacity of single vessel, the cost of new ship, the requirement of minimum departure frequency of route line and the importance that decision-makers attach to studying the physical book value of fleet at the end of the period. On the basis of constructing the mathematical model of liner shipping line assignment, aiming at the maximum discounted profit of liner fleet during the research period, the mathematical optimization model of liner fleet planning is constructed. In order to solve the problem in practical application, the mixed programming technology of Visual Basic and LINGO is used. The application software of liner fleet planning is designed and developed. The software is simple to operate and can realize friendly man-machine interaction. It can input the initial known data according to the user. In order to provide fast and accurate reference data for users, the optimal scheme of fleet development and the corresponding route ship assignment scheme are solved during the research period. In this paper, the validity of the model is verified by the fleet planning case of a liner company in 2015-2019. The results of repeated tests show that the software runs stably, the calculation results are correct, and it has strong practicability. It can provide good fleet planning decision support for liner transportation organizers.
