【摘要】：国际海运对世界经济、国际贸易的迅速发展与不断扩大有着重大的影响作用,它已成为推动世界经济一体化、国际贸易全球化的基础性产业。海运市场的变化,它主要取决于供求这两个方面,即世界海运船队的规模和其海运量。船队规模在不断的增大,海运量则会随着经济贸易的改变而改变,作为从事海洋运输的企业来说,如何在新的竞争环境下达到既能满足客户特定的服务需求又可以获得较大利润回报的目标是非常值得研究的课题。因此,本文以海上运输系统为研究对象,拟研究一种优化方法,以充分利用资源,提高船舶航次经济效益,旨在为企业的经营策略决策提供帮助。文中在对国内外大量相关文献进行分析和研究的基础上,提出了海洋运输现今主要存在的几种方式,并定义了海运企业运输系统的构成,它涉及货类、装卸港口、海运航线、船舶等诸多因素。论文以时间为突破口,把货主的时间要求定义为船舶到港的时间限制,从而把船舶航线规划问题抽象为寻找可行途径的问题,通过matlab编程计算,可以得出满意结果。在基于满意路径的运输优化研究中,论文建立了多货种、装卸港、满足运输任务、以最大利润为目标的优化模型。论文还应用了EXTEND系统仿真软件,在船舶可行路径的基础上建立了海运企业运输系统仿真模型。通过已经建立的合理的仿真模型,加入优化模块,设置该模块的各项参数,运行模型,便可得到相应的优化结果。本文选择海运企业运输系统作为研究对象,建立了相应的理论模型并进行了仿真,一定程度上有助于解决我国海运企业过去仅凭经验决策的问题,对于提高企业竞争能力具有一定的现实意义和理论价值。
[Abstract]:International shipping plays an important role in the world economy and the rapid development and expansion of international trade. It has become the basic industry to promote the integration of world economy and the globalization of international trade. The change of shipping market mainly depends on the supply and demand, that is, the size of the world shipping fleet and its sea transport capacity. As the size of the fleet continues to grow, the volume of sea transportation will change with the change of economic and trade. As an enterprise engaged in marine transportation, How to achieve the goal of satisfying the customer's specific service demand and obtaining a large profit return in the new competitive environment is a topic worth studying. Therefore, this paper takes the marine transportation system as the research object, intends to study an optimization method to make full use of the resources and improve the economic benefits of the ship voyage, in order to provide the help for the enterprise to make the decision of the management strategy. Based on the analysis and study of a large number of related documents at home and abroad, this paper puts forward several main methods of ocean transportation nowadays, and defines the constitution of shipping enterprise transportation system, which involves cargo type, loading and unloading port, shipping route, etc. Ship and many other factors. Taking time as the breakthrough point, the paper defines the time requirement of the cargo owner as the time limit for the ship to arrive at port, thus abstracting the ship route planning problem as the problem of finding a feasible way. Through matlab programming, the satisfactory results can be obtained. In the research of transportation optimization based on satisfactory path, the optimization model of multi-cargo, loading and unloading port, satisfying the transportation task and taking maximum profit as the goal is established in this paper. The simulation model of shipping enterprise transportation system is established on the basis of ship feasible path by using EXTEND system simulation software. Through the reasonable simulation model that has been established, adding the optimization module, setting the parameters of the module and running the model, the corresponding optimization results can be obtained. This paper chooses the shipping enterprise transportation system as the research object, establishes the corresponding theoretical model and carries on the simulation, to some extent helps to solve our country shipping enterprise only the experience decision-making question. It is of practical significance and theoretical value to improve the competitive ability of enterprises.
