基于Anylogic的耙吸装驳作业船舶交通组织仿真

为提高耙吸装驳作业时船舶交通组织水平,减少船舶通航延误,介绍耙吸装驳作业工艺,制定作业时船舶交会控制标准,构建系统仿真逻辑模型,运用Anylogic软件进行离散仿真试验。以长江口深水航道为例,采集该水域的船舶交通流特征数据,输入仿真系统并设置作业参数,并对船舶交通组织过程进行仿真,分析不同的作业位置对船舶通航产生的影响,获得受耙吸装驳作业影响的船舶艘次、平均延误时间和船舶延误分布等,进而提出交通组织建议。实例表明:采用Anylogic软件进行离散仿真,能够量化分析耙吸装驳作业对航道通航效率的影响,为船舶交通组织提供科学依据。

Simulation on Vessel Traffic Organization for TSHD Loading Barge Operation Using Anylogic Software

In order to improve the vessel traffic during TSHD(Trailing Suction Hopper Dredger) loading barges, a scheme for controlling vessel encountering is proposed. The process of the TSHD loading barge is described and the logic model for the system simulation is established. Discrete simulation experiments are conducted by means of Anylogic software. Simulations based on the traffic data from the Yangtze estuary deepwater channel are carried out for illustration. The influences of the TSHD operation on ship navigation at different locations are examined. The number of affected ships, the average delay time and the distribution of ship delay are determined, and the traffic organization proposal is put forward. The discrete simulation by means of Anylogic proved it is a feasible way in scientific quantitative analysis of navigation efficiency for TSHD operation.
