Abstract

The study of maneuverability performance of damaged ship is a major and difficult issue in the study of ship, but the evaluation of damaged ship maneuverability which is one of important damaged ship performance has not been found. In order to predict the damaged ship maneuverability and explore one feasible evaluation method, the assessment factors about damaged ship maneuverability are established innovatively based on its some maneuverability experiments, standards and criteria of intact ship maneuverability, and navigation practice. Then, analytic evaluation process(AHP)¿@and grey relational comprehensive evaluation are combined to evaluate the damaged maneuverability of 29000 ton oil tanker in two kinds of damaged conditions. The values of evaluation factors come from the maneuverability experiments which had been done based on a ship model motion intelligent-controller system. The evaluation example indicates that the assessment factors of damaged maneuverability are feasible, and the synthetic assessment method is effective and concise in evaluating damaged maneuverability. The research can provide some references for ship designers and ship commanders, and is also premise to research an intelligent evaluation system of damaged ship maneuverability.

基于加权灰色关联理论的受损船舶操纵性综合评价

受损船舶的机动性能研究是船舶研究中的一个重点和难点问题，但作为受损船舶重要性能之一的受损船舶机动性能评价尚未得到研究。为了预测受损船舶的操纵性，探索一种可行的评价方法，在对受损船舶操纵性进行实验研究的基础上，结合完整船舶操纵性标准和航行实践，创新性地建立了受损船舶操纵性的评价因子。然后，采用层次分析法和灰色关联综合评价相结合的方法，对29000吨级油轮两种受损工况下的受损机动性进行了评价。评价因子的取值来源于基于航模运动智能控制系统的机动性实验。评价实例表明，毁损机动性评价因子是可行的，综合评价方法在毁损机动性评价中是有效而简洁的。该研究可为舰船设计人员和舰船指挥员提供参考，也是研究损伤舰船机动性能智能评估系统的前提。
