【摘要】：國際海運對世界經(jīng)濟、國際貿(mào)易的迅速發(fā)展與不斷擴大有著重大的影響作用,它已成為推動世界經(jīng)濟一體化、國際貿(mào)易全球化的基礎(chǔ)性產(chǎn)業(yè)。海運市場的變化,它主要取決于供求這兩個方面,即世界海運船隊的規(guī)模和其海運量。船隊規(guī)模在不斷的增大,海運量則會隨著經(jīng)濟貿(mào)易的改變而改變,作為從事海洋運輸?shù)钠髽I(yè)來說,如何在新的競爭環(huán)境下達到既能滿足客戶特定的服務(wù)需求又可以獲得較大利潤回報的目標(biāo)是非常值得研究的課題。因此,本文以海上運輸系統(tǒng)為研究對象,擬研究一種優(yōu)化方法,以充分利用資源,提高船舶航次經(jīng)濟效益,旨在為企業(yè)的經(jīng)營策略決策提供幫助。 文中在對國內(nèi)外大量相關(guān)文獻進行分析和研究的基礎(chǔ)上,提出了海洋運輸現(xiàn)今主要存在的幾種方式,并定義了海運企業(yè)運輸系統(tǒng)的構(gòu)成,它涉及貨類、裝卸港口、海運航線、船舶等諸多因素。 論文以時間為突破口,把貨主的時間要求定義為船舶到港的時間限制,從而把船舶航線規(guī)劃問題抽象為尋找可行途徑的問題,通過matlab編程計算,可以得出滿意結(jié)果。在基于滿意路徑的運輸優(yōu)化研究中,論文建立了多貨種、裝卸港、滿足運輸任務(wù)、以最大利潤為目標(biāo)的優(yōu)化模型。 論文還應(yīng)用了EXTEND系統(tǒng)仿真軟件,在船舶可行路徑的基礎(chǔ)上建立了海運企業(yè)運輸系統(tǒng)仿真模型。通過已經(jīng)建立的合理的仿真模型,加入優(yōu)化模塊,設(shè)置該模塊的各項參數(shù),運行模型,便可得到相應(yīng)的優(yōu)化結(jié)果。 本文選擇海運企業(yè)運輸系統(tǒng)作為研究對象,建立了相應(yīng)的理論模型并進行了仿真,一定程度上有助于解決我國海運企業(yè)過去僅憑經(jīng)驗決策的問題,對于提高企業(yè)競爭能力具有一定的現(xiàn)實意義和理論價值。
[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.
