摘要
在为轮船主人的一个机载的决定支持 / 指导系统的框架的线路优化方法论在这份报纸被开发了并且被介绍。方法瞄准与经得起海上风浪的性能期望在航行持续时间的可接受的限制以内的轮船有关的燃料航行费用和风险的最小化。这方法论的部分被连接其他的概率评价方法实现，例如蒙特卡罗，第一个顺序可靠性方法(形式) 和秒顺序可靠性方法(SORM ) ，和 3-D 经得起海上风浪的代码，包括为在 NTUA-SDL 的波浪的增加的抵抗的计算的一个软件工具。全部系统在概率的分析软件 PROBAN 以内是综合的。为为关于预定义的阀值价值的 exceedance 层次的考虑经得起海上风浪的危险的增加的抵抗和概率的评价的计算的二个主要模块此处被详细描述，鉴于他们的实现，确认研究证明了他们的效率进一个机载的优化系统。
A route optimization methodology in the frame of an onboard decision support/guidance system for the ship＇s master has been developed and is presented in this paper. The method aims at the minimization of the fuel voyage cost and the risks related to the ship＇s seakeeping performance expected to be within acceptable limits of voyage duration. Parts of this methodology were implemented by interfacing alternative probability assessment methods, such as Monte Carlo, first order reliability method （FORM） and second order reliability method （SORM）, and a 3-D seakeeping code, including a software tool for the calculation of the added resistance in waves of NTUA-SDL. The entire system was integrated within the probabilistic analysis software PROBAN. Two of the main modules for the calculation of added resistance and the probabilistic assessment for the considered seakeeping hazards with respect to exceedance levels of predefined threshold values are herein elaborated and validation studies proved their efficiency in view of their implementation into an on-board optimization system.
