【摘要】：鐵水聯(lián)運(yùn)集裝箱堆場的有效管理和調(diào)度優(yōu)化是提高港站這一節(jié)點(diǎn)效率的關(guān)鍵。堆場空間資源有效利用雖不會(huì)對港站經(jīng)濟(jì)效益產(chǎn)生直接影響,但其空間資源調(diào)度優(yōu)化可以減少集裝箱在堆場內(nèi)裝卸時(shí)間,提高港站核心競爭力,并為提高港站經(jīng)濟(jì)效益打下良好基礎(chǔ)。本文以鐵水聯(lián)運(yùn)集裝箱港站為載體,以集裝箱堆場空間資源為研究對象,針對集裝箱堆場箱區(qū)分配和箱位指派兩個(gè)問題,對堆場箱位分配方法進(jìn)行研究,形成考慮船舶配載要求的堆場集裝箱堆存方法。為獲得高效合理的鐵水聯(lián)運(yùn)集裝箱堆場箱位分配方法,本文的主要研究內(nèi)容如下:(1)鐵水聯(lián)運(yùn)集裝箱堆場空間資源優(yōu)化分析。通過對鐵水聯(lián)運(yùn)節(jié)點(diǎn)作業(yè)空間范圍進(jìn)行界定,對集裝箱在節(jié)點(diǎn)處的作業(yè)流程進(jìn)行分析,指出堆場空間資源評價(jià)指標(biāo)形式包括堆場空間資源利用率、堆場空間資源使用均衡度、集裝箱堆場堆存總箱時(shí)。在此基礎(chǔ)上,分析不同集裝箱量的堆存模式的區(qū)別,以集裝箱在港站內(nèi)的作業(yè)效率為目標(biāo),指出在研究周期內(nèi)適用于每種堆存方式的集裝箱箱量大小。(2)集裝箱箱區(qū)分配優(yōu)化研究。以最小化集裝箱堆存占用箱區(qū)貝位數(shù)為目標(biāo),考慮將屬于同一船舶的集裝箱集中堆存以方便裝卸作業(yè),建立時(shí)空范圍上的箱區(qū)分配模型,船舶堆存區(qū)域大小由屬于該船舶的集裝箱箱量確定。模型從時(shí)間和空間兩方面對集裝箱堆存方法進(jìn)行優(yōu)化,即當(dāng)某一船舶的集裝箱尚未到達(dá)港站,集裝箱尚未堆存在屬于該船舶的堆存區(qū)域時(shí),這一區(qū)域可堆存其他船舶的集裝箱;當(dāng)該船舶到達(dá)港站時(shí),這一區(qū)域空閑。并設(shè)計(jì)禁忌搜索算法對箱區(qū)分配優(yōu)化模型求解。(3)集裝箱箱位指派方法研究。以最小化集裝箱堆存時(shí)貝位內(nèi)壓箱量為目標(biāo),考慮在進(jìn)行裝船作業(yè)時(shí)所遵循的配載圖,將船舶配載評估因素簡化為集裝箱終到港和集裝箱箱重兩個(gè)評估因素,在貝位范圍內(nèi)設(shè)計(jì)箱位指派模型,為集裝箱指派較優(yōu)化的箱位。并借鑒鐵路調(diào)車作業(yè)中的車組下落過程設(shè)計(jì)算法進(jìn)行求解。鐵水聯(lián)運(yùn)集裝箱在堆場空間資源進(jìn)行優(yōu)化,不僅能夠?yàn)殍F水聯(lián)運(yùn)節(jié)點(diǎn)調(diào)度優(yōu)化提供理論和現(xiàn)實(shí)參考,實(shí)現(xiàn)集裝箱在港站內(nèi)堆存資源的優(yōu)化;而且科學(xué)、高效的方式對堆場空間資源進(jìn)行優(yōu)化,是進(jìn)行集裝箱鐵水聯(lián)運(yùn)網(wǎng)絡(luò)調(diào)度優(yōu)化的前提,也是鐵水聯(lián)運(yùn)網(wǎng)絡(luò)調(diào)度優(yōu)化的基礎(chǔ),同時(shí)能夠?yàn)橹贫ㄨF水聯(lián)運(yùn)鐵路集疏運(yùn)組織計(jì)劃提供依據(jù)。
[Abstract]:The effective management and scheduling optimization of the container yard for combined transport of hot metal and water is the key to improve the efficiency of the terminal. Although the effective utilization of the space resources of the yard will not have a direct impact on the economic benefits of the port and station, the optimization of its spatial resource scheduling can reduce the loading and unloading time of containers in the yard and improve the core competitiveness of the port and station. It also lays a good foundation for improving the economic benefit of the port and station. In this paper, the container space allocation method of container yard is studied for two problems: the allocation of container area and the allocation of container space, taking the container terminal as carrier and the space resource of container yard as the research object. Form a stowage container stowage method considering ship stowage requirements. In order to obtain an efficient and reasonable method of container space allocation for hot metal combined transport container yard, the main contents of this paper are as follows: (1) the optimization analysis of space resources of hot metal combined transport container yard. By defining the working space scope of hot metal-water transport nodes and analyzing the operation process of containers at the nodes, it is pointed out that the evaluation index forms of the yard space resources include the utilization rate of the yard space resources and the equilibrium degree of the yard space resources use. When the main container is stored in the container yard. On the basis of this, the paper analyzes the difference of storage mode of different container volumes, aiming at the efficiency of container operation in port and station. It is pointed out that the container volume is suitable for each storage mode in the research period. (2) the optimization research of container area distribution. In order to minimize the number of bins in the container storage area, the container storage belonging to the same ship is considered in order to facilitate the loading and unloading operation, and the allocation model of the container area in the space-time range is established. The size of the ship's storage area is determined by the container volume belonging to the ship. The model optimizes the method of container storage in both time and space, that is, when the container of a certain ship has not arrived at the port station and the container has not yet been stacked in the storage area belonging to the ship, the container in this area can be stored in the container of other ships; When the ship arrives at the port station, the area is idle. The Tabu search algorithm is designed to solve the optimization model of box allocation. (3) the container location assignment method is studied. With the aim of minimizing the quantity of shellfish in container stowage, considering the stowage diagram followed in the course of loading operation, the assessment factor of ship stowage is simplified to two factors: container final arrival and container weight. Design the box space assignment model in the shellfish range, assign the optimized container space for the container. And draw lessons from the train shunting operation of train fall process design algorithm to solve. The optimization of the space resources of hot metal combined transport containers in the yard can not only provide theoretical and practical reference for the scheduling optimization of hot metal combined transport nodes, but also realize the optimization of container storage resources in the port and station. Moreover, the scientific and efficient way to optimize the space resources of the yard is the premise of the scheduling optimization of the container combined hot metal transport network, and is also the basis of the scheduling optimization of the hot metal combined transport network. At the same time, it can provide the basis for drawing up the organization plan of railway collection and distribution of hot metal-water combined transport.
