【摘要】：伴随商品车滚装船运输市场的蓬勃发展,船舶持续大型化,可以预见多层的商品车滚装船进行多挂靠港的运输会变得越来越普及,对滚装汽车整车运输的需求也会越来越旺盛。为推进商品车滚装船运输市场的可持续发展,相应的商品车滚装船配载优化问题变得不容忽视。基于这一现实问题,本文研究的船舶配载是多层的、多类型商品车的、多装货港的和多卸货港的多阶段的商品车滚装船配载。根据装货港的不同划分成不同阶段,对每个阶段进行配载。即在每个装货港口对这个港口现有的车辆进行配载,船舱会根据车辆所要达到不同的卸货港口来分配相应的船舱(配载面或甲板)和车道,船舱(配载面或甲板)和车道的划分会根据整个航线上各个港口的车辆到达不同卸货港的比例来进行划分,然后采用遗传算法作为主程序,首先利用遗传算法全局优化能力将车辆分配到各层甲板,以航次收益最大化为目标,在此基础上,基于满足现实约束的多层配载的启发式规则,设计启发式-变异算法产生各层甲板的装载方案,并将其嵌入到主程序之中,使启发式算法与遗传算法交互进行,搜索全船及各层甲板的配载优化解。并在此研究基础上,利用计算机技能,开发商品车滚装船的配载系统,实现信息化的管理。
[Abstract]:With the vigorous development of the commercial vehicle ro / ro ship transportation market, the ship continues to be large-scale, it can be predicted that the multi-layer commercial vehicle ro-ship transportation will become more and more popular, and the demand for the Rro-ro-ro vehicle transportation will be more and more vigorous In order to promote the sustainable development of the market of Ro-ro ship transportation of commercial vehicles, the corresponding optimization problem of ro-ro ship stowage of commercial vehicles can not be ignored. Based on this practical problem, the ship stowage studied in this paper is multi-layer, multi-type commercial vehicle, multi-loading port and multi-stage cargo loading port. According to the different loading port divided into different stages, each stage of stowage. That is, at each loading port, the existing vehicles in this port are stowed, and the ship's cabins are allocated corresponding spaces (stowage planes or decks) and lanes according to the vehicle's arrival at a different port of discharge. The division of cabins (stowage planes or decks) and lanes is divided according to the proportion of vehicles arriving at different unloading ports in each port on the entire route, and then genetic algorithms are used as the main program. Firstly, the vehicle is allocated to each deck by using the global optimization ability of genetic algorithm, aiming at maximization of voyage income. On this basis, the heuristic rule of multi-layer stowage is based on satisfying the practical constraints. A heuristic mutation algorithm is designed to generate the loading scheme of each deck, and it is embedded in the main program. The heuristic algorithm and genetic algorithm are interacted to search the optimal solution for the loading of the whole ship and each deck. On the basis of this research, the stowage system of commercial ro-ro ship is developed by using computer skills, and the information management is realized.
