【摘要】：作為支撐集裝箱在碼頭裝卸和轉(zhuǎn)運(yùn)工作的集裝箱碼頭交通系統(tǒng)，其運(yùn)行效率的高低直接決定了碼頭的整體作業(yè)效率和服務(wù)水平，從而影響整個(gè)港區(qū)的道路運(yùn)行情況、港口集疏運(yùn)的服務(wù)水平。對(duì)碼頭建設(shè)前期進(jìn)行優(yōu)化設(shè)計(jì)，在運(yùn)營(yíng)管理階段進(jìn)行優(yōu)化后的運(yùn)輸組織，是保證集裝箱碼頭企業(yè)高效、低成本運(yùn)行的基礎(chǔ)工作。雖然已有包括建立解析模型、仿真軟件等集裝箱碼頭系統(tǒng)的優(yōu)化研究工作，但假設(shè)較多，沒有采用多主體決策方法，無法反映內(nèi)部復(fù)雜的非線性交通行為；僅有的微觀元胞自動(dòng)機(jī)仿真方法僅局限于碼頭系統(tǒng)的某一模塊，二維元胞自動(dòng)機(jī)模型不能刻畫集裝箱在三維空間中的挪移過程。基于此，本文通過建立集裝箱碼頭系統(tǒng)三維元胞自動(dòng)機(jī)模型，對(duì)其交通系統(tǒng)進(jìn)行優(yōu)化研究，主要工作可概括為以下幾個(gè)方面： （1）根據(jù)集裝箱碼頭業(yè)務(wù)流程、集裝箱和集卡的運(yùn)轉(zhuǎn)規(guī)則，建立包括碼頭前沿船邊裝卸子系統(tǒng)、前方堆場(chǎng)子系統(tǒng)、碼頭道路系統(tǒng)和閘口子系統(tǒng)等組成的元胞自動(dòng)機(jī)模型，其中針對(duì)堆場(chǎng)子系統(tǒng)中集裝箱的翻箱和轉(zhuǎn)移采用三維元胞自動(dòng)機(jī)模型進(jìn)行描述，為集裝箱碼頭交通系統(tǒng)優(yōu)化研究提供貼合實(shí)際的仿真工具，為集裝箱碼頭規(guī)劃設(shè)計(jì)、運(yùn)營(yíng)管理優(yōu)化提供基礎(chǔ)平臺(tái)。 （2）采用建立的元胞自動(dòng)機(jī)模型對(duì)碼頭閘口進(jìn)行仿真實(shí)驗(yàn)，從前期場(chǎng)站設(shè)計(jì)和運(yùn)營(yíng)管理兩個(gè)層面為閘口系統(tǒng)的優(yōu)化提供切實(shí)可行的方法。對(duì)比設(shè)置不同通道數(shù)量和緩沖區(qū)長(zhǎng)度下的系統(tǒng)運(yùn)行狀況，確定閘口的合理建設(shè)規(guī)模；提出在不同高峰時(shí)段調(diào)整各功能閘口數(shù)量借助于VMS進(jìn)行顯示，確定不同高峰期不同功能閘口通道的開放數(shù)量。實(shí)驗(yàn)結(jié)果表明采用本研究方法進(jìn)行設(shè)計(jì)和運(yùn)營(yíng)管理，可確保閘口的高效運(yùn)行并最大限度的減少排隊(duì)現(xiàn)象對(duì)港區(qū)道路擁堵所造成的影響。 （3）采用建立的元胞自動(dòng)機(jī)模型對(duì)碼頭交通系統(tǒng)進(jìn)行仿真實(shí)驗(yàn)。對(duì)比設(shè)置不同堆場(chǎng)數(shù)量和配備不同集卡數(shù)量下整個(gè)交通系統(tǒng)的運(yùn)行效率，從系統(tǒng)性的角度確定堆場(chǎng)的合理規(guī)模以及所需配備的集卡數(shù)量。實(shí)驗(yàn)結(jié)果表明，，采用本研究方法進(jìn)行設(shè)計(jì)和運(yùn)營(yíng)管理，可得到優(yōu)化后的堆場(chǎng)數(shù)量和集卡配備數(shù)量，從而實(shí)現(xiàn)集裝箱碼頭交通系統(tǒng)的順暢運(yùn)行和集卡資源的高效利用。
[Abstract]:As a container terminal transportation system, which supports the loading and unloading and transshipment of containers in the terminal, the operation efficiency of the container terminal directly determines the overall operation efficiency and service level of the terminal, thus affecting the road operation of the whole port area. The service level of port collection and distribution. It is the basic work to ensure the efficient and low-cost operation of container terminal enterprises by optimizing the design of terminal construction and the transportation organization after optimization in the stage of operation and management. Although there have been researches on optimization of container terminal systems, such as the establishment of analytical models, simulation software and so on, there are many hypotheses, and the multi-agent decision-making method is not adopted to reflect the complex internal nonlinear traffic behavior. The only microscopic cellular automata simulation method is limited to a certain module of the wharf system. Two-dimensional cellular automata model can not describe the moving process of containers in three-dimensional space. Based on this, this paper establishes the three-dimensional cellular automata model of container terminal system and studies the optimization of its transportation system. The main work can be summarized as follows: (1) according to the container terminal business process, the main work can be summarized as follows: (1) according to the container terminal business process, The operation rules of container and collecting card are established, and a cellular automata model is established, which includes the loading and unloading subsystem at the front of the terminal, the front yard subsystem, the terminal road system and the gate subsystem, and so on. The three-dimensional cellular automata model is used to describe the container turnover and transfer in the yard subsystem, which provides a practical simulation tool for the optimization research of container terminal traffic system, and provides a practical simulation tool for container terminal planning and design. Operation management optimization provides the basic platform. (2) the simulation experiment of wharf gate is carried out by using the established cellular automata model, which provides a feasible method for the optimization of gate system from the two aspects of design and operation management. The reasonable construction scale of the gate is determined by comparing the operating condition of the system with different number of channels and buffer length. It is proposed to adjust the number of each function gate in different peak hours with the help of VMS to determine the opening number of different function gate channel in different peak period. The experimental results show that the design and operation management can ensure the efficient operation of the gate and minimize the impact of queuing on the road congestion in the port area. (3) the simulation experiment of wharf traffic system is carried out by using the established cellular automata model. By comparing the operation efficiency of the whole transportation system with different yard numbers and different collection cards, the reasonable size of the yard and the number of collection cards needed to be equipped are determined from a systematic point of view. The experimental results show that the optimized yard number and the number of card collection cards can be obtained by the design and operation management of this research method, so as to realize the smooth operation of container terminal transportation system and the efficient utilization of card collection resources.
