【摘要】：近些年來,隨著中國集裝箱碼頭吞吐量的迅速膨脹,各個集裝箱碼頭盡可能的提高碼頭堆場的作業(yè)效率。集裝箱碼頭物流系統(tǒng),是指在一定的集裝箱碼頭空間里,由集裝箱、船舶、裝卸搬運機械、泊位、堆場以及通信聯(lián)系等若干相互制約的動態(tài)要素構(gòu)成的有機整體。作為集裝箱運輸系統(tǒng)的樞紐,對加強國內(nèi)、國際間的貿(mào)易往來與提高集裝箱運輸系統(tǒng)的運輸效率具有極其重要的作用。在集裝箱碼頭中與作業(yè)效率相關(guān)的泊位是稀缺資源。泊位與岸橋資源的合理利用,能夠有效的縮短船舶在港時間,提高碼頭的服務(wù)質(zhì)量,實現(xiàn)港口效益的最大化。影響港口堆場作業(yè)效率的主要因素有很多。例如:對集裝箱的吞吐量預(yù)測不準(zhǔn),過多的翻箱作業(yè)和集裝箱碼頭配置問題等。首先,本文對集裝箱碼頭的整個作業(yè)系統(tǒng)進行了詳細的介紹。包括集裝箱碼頭的組成與布局,集裝箱碼頭特點,裝卸工藝,作業(yè)流程與調(diào)度原則,以及本文研究對象大窯灣集裝箱碼頭;其次,對集裝箱碼頭吞吐量預(yù)測模型進行分析與比較,提出一種改進的基于IOWA算子的組合預(yù)測模型,并利用大窯灣集裝箱碼頭歷年的吞吐量來驗證模型有效地提高了預(yù)測精度;再次,針對過度翻箱問題,通過箱位優(yōu)化分配模型以達到降低翻箱量,將箱位分配優(yōu)化模型所確定的碼放方式與垂直式堆碼等堆碼方式進行比較,并采用MATLAB對模型有效性仿真驗證,實踐證明,利用本文提出的算法可以對集裝箱碼頭的翻箱作業(yè)有所改善,從而提高作業(yè)效率;最后,本文利用串聯(lián)排隊網(wǎng)絡(luò)實現(xiàn)了對集裝箱碼頭生產(chǎn)作業(yè)系統(tǒng)的建模,并通過WITNESS對集裝箱碼頭物流系統(tǒng)進行仿真。針對不同的實際情況,選擇合理的岸橋、集卡等機械作業(yè)配比方式,提高碼頭裝卸效率。并對仿真結(jié)果的分析,對集裝箱碼頭的實際應(yīng)用提供參考。論文結(jié)尾對未來進行了展望。
[Abstract]:In recent years, with the rapid expansion of China container throughput, the container terminal yard as far as possible to improve operation efficiency. The container terminal logistics system, refers to the space in a container, a container, ship, cargo handling machinery, berth, yard and an organic whole communication link several interacting dynamic the elements of the container transport system. As the hub, to strengthen domestic and international trade, and improve the efficiency of container transportation system plays a very important role. And the working efficiency in the container terminal berth is scarce resources. The rational use of berth and quay crane resources, can effectively shorten the ship in Hong Kong time, improve the quality of service, to maximize the benefits. The main influence factors of port container yard work efficiency is very much. For example: Incorrect prediction of container throughput, excessive rollover operation and container terminal configuration problems. First, the container terminal of the whole operation system are introduced in detail. Including the composition and layout of container terminal, container terminal, handling technology, as the principle of business process and scheduling, as well as the research object of Dayaowan container terminal secondly, the container throughput; prediction model and comparative analysis, this paper proposes an improved combination forecasting model based on IOWA operator, and the use of Dayaowan container terminal throughput over the years to validate the model can effectively improve the prediction accuracy; thirdly, aiming at the excessive turning box, through the box of optimal allocation model in order to reduce turnover. The amount, compare the storage allocation optimization model of stacking and vertical stacking and stacking method, and the mode of MATLAB The validity of simulation verification, practice has proved that the proposed algorithm can use the container terminals restacking operation has improved, so as to improve the operating efficiency; finally, the tandem queueing network to realize modeling for production and operation system of container terminal, and through the WITNESS simulation of the container terminal logistics system according to the actual situation of different., reasonable selection of shore bridge, truck and other machinery operation ratio, improve the unloading efficiency. And the analysis of simulation results, to provide reference for the actual application of the container terminal. At the end of the prospects in the future.
