摘要
从分析单线航道通航效率影响机理入手,选用单线航道为研究对象,以船速特征为核心要素,选用船舶通过率,通航历时比和航道通畅度等效率度量指标构建单线航道通航效率评价模型;在抽象分析单线航道船舶通航过程的基础上,利用Arena构建单线航道船舶交通流仿真模型,并结合蒙特卡洛仿真思想,仿真探究船速特征与通航效率之间的内在关联关系。研究表明:当船速均值μ> 10 kn,标准差σ<1. 0时,单线航道通航效率的变化幅度<6%,当6 kn <μ<8 kn且1. 0 <σ<1. 5时,单线航道通航效率的变化幅度> 20%。
The general characteristics of navigation process in a single-line lane are analyzed and a mathematic model is built by means of Arena. The model is efficiency-oriented with the parameters to indicate the effectiveness of the lane such as the rate of ship passing,the navigable time rate and the traffic smoothness. The Monte-Carlo simulation is performed to explore the relation between the navigable efficiency of the lane and ship speeds. The simulation show that when the mean ship velocity μ is greater than 10 kn and the standard deviation σ is less than 1. 0,the variation of the navigation efficiency of single-line lane is smaller than 6%. On the contrary,if 6 kn μ 8 kn and 1. 0 σ 1. 5,the variation of the navigation efficiency will be over 20%.
