摘要

提出了一种船舶安全横渡作业的应用方法，以确定在某一时刻如何制定航行方案。这种方法可以使决策者在不同的时间做出合理的判断。本文综合考虑船舶尺寸、航道水文条件、船舶到达模型和船舶航行轨迹等因素，分析了航道中工作船舶与航行船舶的位置关系。采用遗传算法，以工作船的航速和航向为遗传因素，求解了工作船与航道内船舶保持安全距离的作业方案。通过对给定时间范围内各起始时间的渡船方案进行分析，得到工作船与航道内船舶距离最远的最优渡船方案。根据实测数据，利用MATLAB软件进行了仿真，验证了工作船舶穿越航道的模型。结果表明，选择本文提出的导航方案安全可靠，具有较强的应用价值。

MODEL OF WORKING SHIP CROSSING CHANNEL

An application method for working ship crossing safely is proposed to determine how to make navigation scheme at a certain time. This method makes it possible for decision makers to make reasonable judgments at different times. In this paper, the position relationship between working ship and navigation vessel in waterway is analysed by considering the ship size, hydrological conditions of waterway, ship arrival model and ship navigation trajectory. Using genetic algorithm, the operation scheme of keeping a safe distance between the working ship and the vessel in the channel is solved by taking the speed and direction of the working ship as genetic factors. By analysing the crossing scheme at each starting time in a given time range, the optimal crossing scheme with the farthest distance between the working ship and the vessels in the channel is obtained. According to the measured data, the simulation is carried out with MATLAB to verify the model of working ship crossing channel. The results show that it is safe and reliable to choose the navigation scheme proposed in this paper, which has strong application value.
