【摘要】：近20年來(lái),在改革開(kāi)放政策的推動(dòng)下,我國(guó)國(guó)民經(jīng)濟(jì)和對(duì)外貿(mào)易迅速發(fā)展,集裝箱以其方便、快捷、堅(jiān)固以及有利于多式聯(lián)運(yùn)等優(yōu)勢(shì)越來(lái)越廣泛的使用在各種貨物的運(yùn)輸上,但同時(shí)集裝箱的使用也面臨著各國(guó)各地區(qū)貿(mào)易不平衡這一挑戰(zhàn)。這導(dǎo)致進(jìn)口主導(dǎo)港口積累了很多空箱,而出口導(dǎo)向港口迫切需要大量空箱。這使得航運(yùn)公司不得不在各個(gè)港口之間運(yùn)送大量的空集裝箱,空集裝箱的調(diào)配對(duì)于航運(yùn)公司來(lái)說(shuō)這是一筆巨大的運(yùn)營(yíng)成本。因此,解決空集裝箱調(diào)配的問(wèn)題,能幫助航運(yùn)公司降低成本,有助于形成企業(yè)競(jìng)爭(zhēng)力。本學(xué)位論文在使用分布式魯棒優(yōu)化研究空集裝箱調(diào)配問(wèn)題中聯(lián)合考慮了滿載集裝箱,創(chuàng)新性地引入可折疊集裝箱。本學(xué)位論文所討論的標(biāo)準(zhǔn)集裝箱均為20英尺,可折疊集裝箱在打開(kāi)時(shí)規(guī)格與標(biāo)準(zhǔn)集裝箱完全相同,折疊時(shí)體積為標(biāo)準(zhǔn)集裝箱的四分之一�？烧郫B集裝箱不但能節(jié)省堆存空間,同時(shí)還可以節(jié)省艙位空間,這就意味著將大大減少庫(kù)存成本,增加船舶的集裝箱裝載量。其次,可折疊集裝箱還可以提高裝卸效率。對(duì)于集裝箱調(diào)配問(wèn)題,首先建立了集裝箱調(diào)配問(wèn)題的確定性模型。其次,基于確定性模型,我們建立了集裝箱供應(yīng)量與需求量不確定時(shí)的兩階段隨機(jī)規(guī)劃模型和分布式魯棒優(yōu)化模型,并且將分布式魯棒優(yōu)化模型轉(zhuǎn)化為可求解的二階錐規(guī)劃模型。最后,我們利用滾動(dòng)時(shí)域仿真的方法,對(duì)比了三個(gè)模型,得出了在解決集裝箱調(diào)配問(wèn)題的時(shí)候分布式魯棒優(yōu)化模型更具優(yōu)越性,可以為企業(yè)降低更多的成本。
[Abstract]:In the past 20 years, driven by the policy of reform and opening up, China's national economy and foreign trade have developed rapidly. Containers have been more and more widely used in the transport of all kinds of goods because of their advantages of convenience, rapidity, firmness and convenience for multimodal transport. But at the same time, the use of containers is also facing the challenge of trade imbalance between countries and regions. This has led to the accumulation of a lot of empty boxes in import-led ports, while export-oriented ports urgently need a large number of empty boxes. This makes shipping companies have to transport a large number of empty containers between ports, and the deployment of empty containers is a huge operating cost for shipping companies. Therefore, solving the problem of empty container allocation can help shipping companies reduce costs and help to form the competitiveness of enterprises. In this thesis, the problem of empty container allocation is studied by using distributed robust optimization, and the collapsible container is introduced innovatively. The standard containers discussed in this thesis are all 20 feet. The foldable containers are exactly the same as the standard containers when they are opened, and the volume of the standard containers is 1/4 of that of the standard containers at the time of folding. Collapsible containers can not only save storage space, but also save space, which means that the inventory cost will be greatly reduced and the container loading capacity of ships will be increased. Secondly, foldable containers can also improve loading and unloading efficiency. For the container allocation problem, firstly, the deterministic model of container allocation problem is established. Secondly, based on the deterministic model, we establish a two-stage stochastic programming model and a distributed robust optimization model when container supply and demand are uncertain. The distributed robust optimization model is transformed into a solvable second-order cone programming model. Finally, we use the rolling time domain simulation method to compare the three models, and show that the distributed robust optimization model has more advantages in solving the container allocation problem, and can reduce more costs for enterprises.
