【摘要】：隨著國(guó)家“一路一帶”海洋戰(zhàn)略的提出,我國(guó)的航運(yùn)事業(yè)將進(jìn)入一個(gè)新的時(shí)代,這對(duì)于每一個(gè)航運(yùn)企業(yè)來(lái)說(shuō)既是機(jī)遇也是挑戰(zhàn)�！耙宦芬粠А睉�(zhàn)略的實(shí)施將大大拉動(dòng)我國(guó)沿海港口以及周邊港口的貨運(yùn)需求,同時(shí)由于近年來(lái)我國(guó)逐漸放寬航運(yùn)市場(chǎng)的政策限制,國(guó)外航運(yùn)企業(yè)正加大在華投資,這就使得市場(chǎng)的競(jìng)爭(zhēng)更加激烈。航運(yùn)企業(yè)為了生存,不得不從自身下手,根據(jù)營(yíng)運(yùn)區(qū)域內(nèi)的貨運(yùn)需求,通過(guò)選擇合適掛靠港口、優(yōu)化掛靠次序以及合理配置運(yùn)行船舶等方法來(lái)優(yōu)化設(shè)計(jì)集裝箱班輪航線,從而降低運(yùn)營(yíng)成本、提高運(yùn)輸服務(wù)質(zhì)量。港口貨運(yùn)時(shí)間窗特性給集裝箱班輪航線的優(yōu)化設(shè)計(jì)帶來(lái)了很大的不確定性。各港口間的貨運(yùn)需求量會(huì)因?yàn)榇皰炜扛劭诘臅r(shí)間而不同,因此在航線設(shè)計(jì)的時(shí)候就不能只考慮掛靠港口的順序。集裝箱班輪航線設(shè)計(jì)的對(duì)象是一個(gè)由港口、船舶、集裝箱構(gòu)成,需要從路徑構(gòu)建、資產(chǎn)配置、運(yùn)營(yíng)操作3個(gè)層面一體確定掛靠港口、掛靠順序、艙位分配、船舶配置、箱量配備,才能實(shí)現(xiàn)優(yōu)化運(yùn)作的運(yùn)營(yíng)系統(tǒng)。本研究重點(diǎn)討論了集裝箱班輪運(yùn)輸?shù)奶攸c(diǎn),并引入港口貨運(yùn)需求時(shí)間窗這一概念,通過(guò)分析港口貨運(yùn)需求時(shí)間窗影響因素,說(shuō)明考慮該港口貨運(yùn)需求時(shí)間窗是符合實(shí)際的。然后本文利用整數(shù)規(guī)劃、車輛路徑選擇理論、非線性規(guī)劃等一系列數(shù)學(xué)理論對(duì)加入港口貨運(yùn)需求時(shí)間窗的航線優(yōu)化問(wèn)題進(jìn)行數(shù)學(xué)建模,同時(shí)將單位時(shí)間單艙利潤(rùn)最大作為目標(biāo)函數(shù)值進(jìn)行優(yōu)化。在模型的求解上本文采用雙層遺傳算法,并借助數(shù)學(xué)軟件求解出航線設(shè)計(jì)問(wèn)題包含的掛靠港口選擇、掛靠順序確定、艙位分配、船型及船隊(duì)規(guī)模等方案。最后將該方法應(yīng)用到實(shí)際當(dāng)中,進(jìn)行航線優(yōu)化設(shè)計(jì),通過(guò)數(shù)字實(shí)驗(yàn),論證本文的實(shí)際應(yīng)用價(jià)值。
[Abstract]:With the national "Belt and Road" marine strategy put forward, China's shipping industry will enter a new era, which is both an opportunity and a challenge for every shipping enterprise. The implementation of the "Belt and Road" strategy will greatly boost the freight demand of China's coastal ports and its surrounding ports. At the same time, foreign shipping enterprises are increasing their investment in China because China has gradually relaxed the policy restrictions on the shipping market in recent years. This makes the market more competitive. In order to survive, shipping enterprises have to start from their own, according to the freight demand in the operation area, by selecting the appropriate port, optimizing the order of connection and reasonable configuration of the running ship to optimize the design of container liner routes. In order to reduce operating costs, improve the quality of transport services. The time window characteristic of port freight brings great uncertainty to the optimization design of container liner route. The demand for cargo between ports will vary according to the time during which the ship is linked to the port, so the sequence of ports should not be considered only in the course design. The object of container liner route design is composed of port, ship and container, which needs to determine the connection port, the order of connection, the allocation of cabin space and the configuration of ship from three levels: path construction, asset allocation and operation. In order to achieve the optimal operation of the operation system. This study focuses on the characteristics of container liner transportation, and introduces the concept of port freight demand time window. By analyzing the influence factors of port freight demand time window, it is shown that considering the port freight demand time window is in line with the reality. Then a series of mathematical theories, such as integer programming, vehicle routing theory, nonlinear programming and so on, are used to model the route optimization problem with port freight demand time window. At the same time, the maximum profit per unit time single cabin is optimized as the objective function value. In the solution of the model, this paper adopts the double layer genetic algorithm, and uses the mathematical software to solve the route design problems including the choice of the port, the determination of the alignment sequence, the allocation of the cabin space, the ship type and the size of the fleet, and so on. Finally, the method is applied to practice, and the practical application value of this paper is proved by digital experiment.
