【摘要】:目前,隨著我國人口數(shù)量的持續(xù)在增長,導(dǎo)致了土地資源的人均占有量變少,進(jìn)而使得土地資源緊缺。因此,國家政府部門對港口占地面積約束限制越來越嚴(yán)格。目前,國內(nèi)外各類大小港口發(fā)展需要共同解決增強港口吞吐能力、挖掘開發(fā)潛力以及管理體制完善等課題。一些發(fā)達(dá)國家現(xiàn)代化港口的管理水平比國內(nèi)高得多,比如對于同一規(guī)模的港口,國外吞吐量能力比國內(nèi)強數(shù)倍。通過設(shè)備投入增加,可以加快集裝箱裝卸速度,但也會增加成本投入。顯然,集裝箱裝卸效率的提高十分重要,因此,運用科學(xué)的集裝箱港口裝卸工藝流程來提高集裝箱裝卸效率很關(guān)鍵。 集裝箱港口集卡調(diào)度包括運輸與裝卸,同時又由于集卡數(shù)量的增多、集裝箱港口集裝箱數(shù)量增加、集裝箱港口規(guī)模擴(kuò)大等,這些因素造成集卡調(diào)度工作變得很復(fù)雜。所以,如何提高港口集卡工作效率是使集裝箱港口生產(chǎn)率獲得提高的必要條件。 本文首先通過對天津港(集團(tuán))有限公司港口集卡調(diào)度的調(diào)研,熟悉并掌握該公司的水平運輸作業(yè)工藝流程,并收集了相關(guān)數(shù)據(jù)。然后結(jié)合實際情況明確集裝箱港口的功能布局,業(yè)務(wù)流程作業(yè)資源及其設(shè)備配置。運用蟻群遺傳算法理論知識及相關(guān)數(shù)據(jù)來確定港口水平運輸工藝作業(yè)流程優(yōu)化的目標(biāo)。緊接著建立了面向“作業(yè)面”的集卡調(diào)度優(yōu)化模型。最后依據(jù)天津港的實際作業(yè)情形及相關(guān)數(shù)據(jù)設(shè)計案例,,并運用Matlab優(yōu)化工具箱求解出最佳的調(diào)度方式和調(diào)度路徑。 本文結(jié)合集裝箱港口水平運輸作業(yè)工藝,采用ACO智能優(yōu)化算法,給國內(nèi)外港口企業(yè)構(gòu)建一個可操作性強以及實用性高的方法,并為優(yōu)化水平運輸作業(yè)提供依據(jù)。本文理論意義和現(xiàn)實作用,主要表現(xiàn)為如下四方面:(l)完善和發(fā)展集裝箱港口水平運輸系統(tǒng)的理論體系;(2)為完善我國集裝箱港口水平工藝優(yōu)化提供可行方法;(3)通過優(yōu)化其水平運輸工藝,可提高集裝箱港口的生產(chǎn)效率,促進(jìn)集裝箱港口的發(fā)展;(4)解決集裝箱港口水平運輸系統(tǒng)存在的問題,對開展多式聯(lián)運、實現(xiàn)交通運輸現(xiàn)代化作貢獻(xiàn)。
[Abstract]:At present, with the continuous increase of population in our country, the per capita possession of land resources becomes less, which makes the land resources scarce. As a result, the state government has more and more strict restrictions on the port area. At present, all kinds of port development at home and abroad need to solve the problems of enhancing port handling capacity, tapping development potential and perfecting management system. In some developed countries, the management level of modern ports is much higher than that of domestic ones, for example, for ports of the same size, the throughput capacity of foreign countries is several times stronger than that of domestic ports. Through the equipment input increases, may speed up the container loading and unloading speed, but also will increase the cost input. Obviously, the improvement of container handling efficiency is very important, so it is very important to use scientific container port handling process to improve container handling efficiency. Container port card collection scheduling includes transportation and loading and unloading. At the same time, due to the increase of the number of container cards, the number of container ports, container port scale expansion and so on, these factors make card collection scheduling work become very complex. Therefore, how to improve the efficiency of port card collection is the necessary condition to improve the productivity of container port. In this paper, through the investigation of Tianjin Port (Group) Co., Ltd, we are familiar with and master the horizontal transportation process of Tianjin Port (Group) Co., Ltd, and collect the relevant data. Then, the function layout, operation resource and equipment configuration of container port are defined in combination with the actual situation. Ant colony genetic algorithm (AGA) theory and related data are used to determine the target of port horizontal transportation process optimization. Then, the optimization model of card scheduling for "job surface" is established. Finally, according to the actual operation situation of Tianjin Port and the relevant data design cases, the optimal scheduling mode and scheduling path are solved by using the Matlab optimization toolbox. Combined with container port horizontal transportation operation technology and ACO intelligent optimization algorithm, this paper provides a feasible and practical method for port enterprises at home and abroad, and provides the basis for optimizing horizontal transportation operation. The theoretical significance and practical function of this paper are as follows: (1) the theoretical system of improving and developing the container port horizontal transportation system in four aspects of: (l); (2) providing a feasible method for the perfection of China's container port horizontal process optimization; (3) by optimizing the horizontal transportation technology, the production efficiency of container port can be improved and the development of container port can be promoted. (4) solving the problems of container port horizontal transportation system and contributing to carrying out multimodal transport and realizing transportation modernization.
