【摘要】:隨著經(jīng)濟(jì)全球化的深入推進(jìn),世界航運(yùn)業(yè)格局發(fā)生了深刻變化,國(guó)際航運(yùn)市場(chǎng)日益出現(xiàn)船舶大型化、經(jīng)營(yíng)聯(lián)盟化和運(yùn)輸干線網(wǎng)絡(luò)化,加劇了港口間的競(jìng)爭(zhēng)。劇烈的港際競(jìng)爭(zhēng)促使海港重視與內(nèi)陸地區(qū)的緊密結(jié)合,紛紛在內(nèi)陸地區(qū)投資興建無(wú)水港。無(wú)水港是沿海港口的國(guó)際物流服務(wù)功能在內(nèi)陸的延伸,它的出現(xiàn)可以視為港口區(qū)域化、供應(yīng)鏈管理平臺(tái)化和擴(kuò)展門戶等物流理論的一種現(xiàn)實(shí)體現(xiàn)。無(wú)水港具有口岸功能、運(yùn)輸功能、物流和供應(yīng)鏈功能、增值服務(wù)功能、保稅物流功能和產(chǎn)業(yè)集聚功能。作為一個(gè)節(jié)點(diǎn),無(wú)水港對(duì)集裝箱貨流組織及其路徑安排產(chǎn)生了重要影響,現(xiàn)有區(qū)域集裝箱運(yùn)輸組織和路徑問(wèn)題的文獻(xiàn)很少考慮無(wú)水港的影響,尤其是忽視了其口岸功能帶來(lái)的影響。 針對(duì)目前研究中的主要問(wèn)題,本文從兩方面開(kāi)展研究:一是在全球海運(yùn)物流網(wǎng)絡(luò)中考慮無(wú)水港轉(zhuǎn)運(yùn)功能,構(gòu)建擴(kuò)展的集裝箱出口流運(yùn)輸網(wǎng)絡(luò),采用最低成本戰(zhàn)略,建立了基于無(wú)水港轉(zhuǎn)運(yùn)功能的內(nèi)陸地區(qū)集裝箱出口流優(yōu)化模型,設(shè)計(jì)了基于擴(kuò)展優(yōu)先權(quán)編碼的自適應(yīng)遺傳算法求解;二是在考慮無(wú)水港轉(zhuǎn)運(yùn)的基礎(chǔ)上,進(jìn)一步考慮其海關(guān)清關(guān)功能,建立了基于無(wú)水港口岸功能的內(nèi)陸地區(qū)集裝箱出口流運(yùn)輸網(wǎng)絡(luò)和優(yōu)化模型,模型的目標(biāo)是使總成本最低,成本包括內(nèi)陸運(yùn)輸成本、海上運(yùn)輸成本、無(wú)水港轉(zhuǎn)運(yùn)成本,,無(wú)水港和海港的清關(guān)成本,并設(shè)計(jì)進(jìn)化算法求解,為提高算法的有效性,算法中集成了移民策略和領(lǐng)域搜索技術(shù)。利用仿真軟件,本文分別對(duì)兩個(gè)模型進(jìn)行了算例分析。
[Abstract]:With the development of economic globalization, the pattern of the world shipping industry has undergone profound changes. The international shipping market is increasingly becoming large-scale, the operation alliance and the network of transportation trunk lines have intensified the competition between ports. Intense interharbour competition has prompted the port to focus on its close integration with inland areas and invest in waterless ports. The waterless port is the extension of the international logistics service function of the coastal port in the inland. Its appearance can be regarded as a realistic embodiment of the logistics theory such as the port regionalization, the supply chain management platform and the extended portal. The waterless port has port function, transportation function, logistics and supply chain function, value-added service function, bonded logistics function and industrial agglomeration function. As a node, waterless ports have an important impact on container traffic organizations and their routing arrangements, and the existing literature on regional container transport organizations and routing issues rarely considers the effects of waterless ports. In particular, the impact of its port function has been neglected. In view of the main problems in the current research, this paper has carried out research from two aspects: first, considering the waterless port transshipment function in the global maritime logistics network, Based on the lowest cost strategy, the optimal model of container export flow in inland area is established, and the adaptive genetic algorithm based on extended priority coding is designed. Second, on the basis of considering the transshipment of waterless ports and further considering its customs clearance function, a container export flow transportation network and optimization model for inland areas based on the functions of waterless ports are established. The objective of the model is to minimize the total cost. The cost includes inland transportation cost, sea transportation cost, waterless transportation cost, clearance cost of waterless port and seaport, and evolutionary algorithm is designed to solve the problem. In order to improve the efficiency of the algorithm, immigration strategy and domain search technology are integrated in the algorithm. Using the simulation software, the two models are analyzed with examples.
