为解决复式航道中存在的船舶交通冲突,以天津港复式航道为原型,抽象出一种Y形分叉复式航道模型.基于该航道船舶交通流特点及航行规则,划定影响航道船舶交通的三个关键区域,分别构建航道入口处主、辅航道及航行模式分配模型,警戒区主、辅航道交通流转换模型及Y字航道口分合流模型,以船舶总等待时间最小为目标函数,建立复式航道船舶调度数学模型,并设计相应的遗传算法求解模型.基于船舶进出复式航道模拟数据,利用MATLAB进行仿真实验.经过航行连续性、安全性、调度高效性分析,验证了模型的合理性及算法的有效性,可为VTS管理人员进行复杂水域船舶交通管理提供辅助决策.

To solve the vessel traffic conflict in the compound waterway, taking Tianjin port compound waterway as prototype, a Y shaped bifurcation compound waterway model was proposed. Based on the traffic flow characteristics and navigation rules of the waterway, three key areas which affected the vessel traffic of compound waterway significantly were designated, and the corresponding models of waterway and navigation mode allocation in entrance, traffic flow of main and auxiliary waterway conversion in precautionary area, traffic flow division and merge in Y cross area were proposed. The compound waterway vessel scheduling mathematical model was designed which took minimum total waiting time as the objective function and a compound waterway vessel scheduling algorithm (CWVSA) was proposed to solve the model. Furthermore, a simulation experiment of vessel scheduling by using MATLAB was carried out based on the simulation data of vessel entering and leaving complex waterway. Finally, through the analysis of navigation continuity, safety and efficiency, the rationality of the model and the effectiveness of the algorithm were verified, which can provide assistant decision for VTS operators to manage vessel traffic in complex waters.
