基于元胞自动机的船舶过闸运输组织仿真

三峡水利枢纽船闸设计通行能力与船闸实际通过能力不足的矛盾日益突出,为解决这一尴尬现实,将三峡船闸入口船舶流特征与道路交通中三线轨道交通模型结合起来,运用船舶过闸调度原理和元胞自动机理论构建了水利枢纽区域过闸组织模型,并对双向船闸和升船机组成的过闸系统进行模拟。研究结论反映了船舶达到规律对船舶流聚集和疏散的影响。最后对仿真结果给出具体的分析。

Simulation of ship lock organization mode with cellular automata

Nowadays, the contradiction between the designed capacity of lockage and the practical capacity in hydro-junction is becoming increasingly prominent. Therefore, this paper combines vessel flow characteristics with three-line rail traffic model in road traffic to solve this problem. Moreover, an organized model for hydrojunction lockage is set up based on the scheduling theory and cellular automata theory. Besides, by simulating the lockage system which consists of two-way navigation lock and ship lift, the pattern of the coming ships is studied to analyze its influences on the converging and diverging ship flow. Finally, a specific analysis is obtained through the simulation results.
