【摘要】：随着集装箱班轮运输业的迅速发展,班轮配船日益受到重视。配船的成功与否直接影响到企业目前的营运与未来的发展。九十年代货源充足时,大部分公司配船的目的是追求利润最大化；随着班轮市场运力的不断提升,尤其是受金融危机的影响,班轮公司的盈利越来越微薄,亏损现象比比皆是,此时的配船是在满足运力的条件下,追求成本最小。班轮因其服务的便捷性、可靠性与准时性而受欢迎,货物集装箱化程度越来越高是必然现象,短时间内班轮运输业或许会受到国际经济形势的影响,出现低谷现象。但从发展趋势来看,班轮运输市场将继续发展壮大,并趋向运力与运量平衡。因此,班轮公司应该从长远发展出发,配备现有船舶,既不让现有船舶闲置,又不致公司入不敷出；更重要的是能吸引更多的货源,占领更多的市场份额,为公司的长久发展创造机会、铺垫基础。同时,充分考虑船舶速度对船舶配置的影响,在航运低迷期,可以通过速度的调节吸纳更多的运力；而在航运高峰期则可以提高速度,从而为集装箱货主提供更便捷及时的运输服务。 本文基于上述理念,参照已有模型,提出了以船舶速度和船舶数量为决策变量的班轮航线配船模型。在考虑船舶速度的基础上,分别针对航运上行期和下行期建立数学模型,在航运上行期以收益最大为目标,为公司创造尽可能多的利润,而在航运下行期,则以营运成本为目标,为公司将成本降至最低。本文运用禁忌搜索算法对模型进行求解,并设计了c语言程序,数值试验的结果证明模型具有一定的实际运用价值。
[Abstract]:With the rapid development of container liner transportation, liner allocation has been paid more and more attention. The success of ship allocation has a direct impact on the current operation and future development of the enterprise. When the supply of goods was sufficient in the 1990s, the purpose of most companies to allocate ships was to maximize profits. With the continuous improvement of liner market capacity, especially affected by the financial crisis, the profits of liner companies are becoming thinner and thinner, and the phenomenon of losses is everywhere. At this time, the allocation of ships is in the pursuit of the smallest cost under the condition of meeting the capacity. Liner is popular because of the convenience, reliability and timeliness of its service. It is an inevitable phenomenon that the degree of container loading is getting higher and higher. In a short period of time, the liner transport industry may be affected by the international economic situation, and there will be a trough phenomenon. However, from the point of view of the development trend, the liner transport market will continue to develop and expand, and tend to balance the capacity and volume. Therefore, the liner company should proceed from the long-term development, equipped with the existing ship, neither let the existing ship idle, nor the company can not make ends meet; More importantly, it can attract more supply, occupy more market share, create opportunities and lay the foundation for the long-term development of the company. At the same time, fully considering the influence of ship speed on ship configuration, in the period of shipping downturn, more capacity can be absorbed through the adjustment of speed. In the peak period of shipping, it can improve the speed, so as to provide more convenient and timely transportation services for container owners. Based on the above concepts and referring to the existing models, a liner route allocation model with ship speed and ship number as decision variables is proposed in this paper. On the basis of considering the speed of the ship, the mathematical models are established for the upstream and downgoing periods of shipping respectively. the maximum profit is taken as the goal of the shipping advance period, so as to generate as many profits as possible for the company, while in the shipping downgoing period, It aims at operating costs and minimizes costs for the company. In this paper, Tabu search algorithm is used to solve the model, and a c language program is designed. The results of numerical experiments show that the model has certain practical application value.
