基于DHGF法的船舶操纵性综合评价 总被引:1,自引:0,他引:1
在深入研究船舶的操纵性能的特点和各种系统评价方法的基础上,提出一种使用方便且行之有效的船舶操纵性能的综合评价方法。首先,在船舶固有操纵性基础上,建立了操纵性的指标体系。在深入研究Delphi法、层次分析法(AHP)、灰色关联度法以及模糊综合分析法的基础之上,提出DHGF集成法,阐述了该方法的构造原理和计算步骤。最后,将DHGF理论应用于船舶操纵性评价的实践中,得出船舶操纵性评价的结果与实际情况相同。提出DHGF集成法不仅在理论上具有优越性、科学性,在应用中也具有可靠性和可操作性,从而对工程上船舶的操纵性评价具有一定参考价值。 相似文献

将离差最大化方法应用到船舶操纵性综合评价中,引入加权向量和规范化决策矩阵,考虑各个操纵指标的权重和规范化决策矩阵对操纵性评价的影响,建立船舶操纵性综合评价体系,阐述该方法的构造原理和操作步骤。选取两个试验船模作为评价对象,以回转角速度、相对回转直径、初转期、第一超越角和第二超越角作为操纵性评价指标,分别求取两船模的操纵性评价指标的加权向量和规范化决策矩阵,并对计算得到的综合评价指标进行了分析,其结果与船模K,T,P指数一致,可以将离差最大化方法用于船舶操纵性综合评价中。 相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 相似文献
