  • 简介:许多海洋交通中心系统由分享在区域处理生意的容器的二个容器港口组成。通过一个港口的容器流动是港口竞争力的主要测量。在这份报纸,我们收养一个Hotelling模特儿在一个所谓的双网关港口系统学习容器端口比赛。系统包含二个端口和二个终端,属于每个端口的。二个港口在被找到的二个政府在货物费用上竞争,二个终端决定服务价格和服务质量。我们与在终端之间的竞争的不同层次学习二个模型。在第一个模型,二个终端被二个不同操作符并且在第二个模型,拥有二个终端在一个操作符下面是集中的。第二个模型在实践存在,但是不是在文学学习的井。我们为这二个模型导出货物费用,终端服务价格,和服务质量equilibria。我们与数字研究调查比赛结果敏感。数字结果表明政府们比较喜欢终端与对方竞争。如果终端没在他们的服务质量有竞争优势,那么,终端集中化比比赛案例把更多的利润带到终端操作员。

  • 简介:以便更精确地在粗野货物产量检验发展中的趋势,我们为货物产量的概率分发建模。等到在港口和处理设备的操作效率乘货物轮船花了,粗野货物产量被决定。粗野货物产量是为到达港口的每艘货物轮船决定货物产量的每个方面的所有复合变量的和。概率分发用Wald方程被决定。结果证明粗野货物产量的可变性首先取决于到达港口的不同货物轮船要求的不同时间。这个模型克服以前的模型的缺点:精确地决定未来的特定的价值的概率的无能粗野货物产量。我们货物产量的建议模型取决于在到达港口和在港口处理设备的运作的能力的一艘货物轮船要求的时间之间的关系。同时,影响粗野货物产量的关键因素被分析。为了测试模型,的效率,在山东省的一个端口的货物卷被用作一个例子。在案例研究,实际结果匹配我们的理论分析。
