【摘要】：集装箱班轮航线设计是班轮公司的重要战略决策,直接关系到航线配船和船型选择,对班轮公司的运营成本和效益产生长远的影响。随着近年来集装箱航运市场需求的剧烈波动,船公司在运力过剩的环境下面临更加严峻的竞争形势,在当前的情况下,除了价格竞争之外,班轮公司如何依据运营区域内货流需求和港口条件,科学合理地优化设计班轮航线,提高服务水平也是船公司保持市场份额的重要方式。目前学界和业界在研究班轮航线系统优化问题时大多数仅考虑班轮企业的运营成本,而忽略了托运人因货物等待装运或在海上运输途中产生的库存成本。如果仅站在班轮企业的角度优化航线问题,就有可能将班轮企业多获得的利润作为成本转嫁到托运人身上。那么,托运人站在自身的角度考虑问题,很可能不会选择该班轮企业进行货物运输,使得班轮航线系统优化方案并非最优。为改进集装箱班轮航线系统的设计优化问题,结合集装箱班轮航线运输特点,在满足区域内集装箱货运需求的前提下,通过综合考虑在集装箱运输过程中与托运人有关的库存成本以及承运人运营成本,本文研究构建了集装箱航线系统优化模型。本文首先详细介绍了集装箱运输的相关概念和理论,包括集装箱运输及航线的特点、集装箱班轮运行过程、集装箱班轮运输发展特征以及集装箱班轮航线系统优化设计的必要性等问题；后对集装箱班轮航线系统展开细致研究,将集装箱班轮航线系统分为承运人运输系统和在托运人库存系统,并详细的介绍了班轮航线系统优化设计的影响因素,分析决策变量之间的影响关系；然后建立了班轮航线系统路径优化模型,并详细分析了承运人的运营成本模型和托运人的库存成本模型；最后选取算例分析,设计遗传算法进行求解,验证了模型的适应性和有效性。
[Abstract]:The container liner route design is an important strategic decision of the liner company, which is directly related to the choice of the shipping line and the ship type, and has a long-term impact on the operating cost and efficiency of the liner company.With the rapid fluctuation of container shipping market demand in recent years, shipping companies are facing a more severe competition situation under the environment of excess capacity. In the current situation, in addition to price competition,How to optimize the liner route scientifically and reasonably according to the cargo flow demand and port conditions in the operating area and improve the service level is also an important way for the shipping company to maintain its market share.At present, most scholars and industries only consider the operating costs of liner companies when studying the optimization of liner routes system, while ignoring the inventory costs of shippers due to goods waiting to be shipped or in transit by sea.If only from the point of view of the liner company to optimize the route, it is possible to transfer the extra profit earned by the liner company to the shipper as the cost.Therefore, shippers may not choose the liner company to carry out cargo transportation from their own point of view, which makes the optimization scheme of liner route system not optimal.In order to improve the design and optimization of container liner shipping system, combined with the characteristics of container liner shipping, under the premise of satisfying the demand of container freight in the region,By considering the inventory cost related to shippers and the carrier's operating cost in container transportation, this paper studies the optimization model of container route system.This paper first introduces the concept and theory of container transportation in detail, including the characteristics of container transportation and route, the operation process of container liner,The development characteristics of container liner transportation and the necessity of optimal design of container liner shipping line system are discussed.The container liner route system is divided into carrier transportation system and shippers inventory system, and the influence factors of optimal design of liner route system are introduced in detail, and the influence relationship between decision variables is analyzed.Then, the route optimization model of liner route system is established, and the operating cost model of carrier and the inventory cost model of shipper are analyzed in detail. Finally, an example is selected and genetic algorithm is designed to solve the problem.The adaptability and validity of the model are verified.
