9506707 Duraiswami The research is directed at developing a PC-based, user-friendly, on-board multitasking ship maneuvering simulator incorporating operation in confined water and under the action of wind and waves. The objectives are to extend the multi-objective identification method to on-board identification using on-board measurements; reduce structural uncertainty in the model through invoking alternative mathematical models for the same ship and create a database of models for various types of ships and different environment conditions. This would lead to the development of multitasking software for simulating several ships simultaneously and its implementation with a user-friendly and realistic graphical interfaces. A library of mathematical models for different ship configurations, and environmental conditions of wind, sea state, proximity of channel-sides and walls will be created based on existing fundamental models for ship hydrodynamics. A new multiobjective identification approach that uses a set of mathematical models for parameter identification of the same system will also be developed to reduce structural uncertainty of the model. These developments will allow simulation of different types of ships navigating in critically important situations.

9506707 杜赖斯瓦米 本研究旨在开发一种基于PC机的、用户友好的、包括在承压水和风浪作用下操作的船上多任务船舶操纵模拟器。 其目标是将多目标识别方法扩展到使用船上测量的船上识别;通过调用同一船舶的替代数学模型来减少模型中的结构不确定性，并创建用于各种类型的船舶和不同环境条件的模型数据库。 这将导致开发多任务软件，同时模拟几艘船舶，并实现用户友好和逼真的图形界面。 将根据现有的船舶水动力学基本模型，建立一个不同船舶配置以及风、海况、航道两侧和墙壁邻近度等环境条件的数学模型库。 一个新的多目标识别方法，使用一组数学模型的参数识别相同的系统也将被开发，以减少模型的结构不确定性。 这些发展将允许模拟不同类型的船舶在至关重要的情况下航行。
