Investigation on Broaching-to Using Optimal Control Theory
Broaching Optimal Control Theory
2009/4/10
Broaching-to is a phenomenon in which a ship cannot keep her desired course despite the maximum steering effort. Once this dangerous phenomenon happens, she could capsize due to violent yaw motion. Ge...

ship-building discrete-event system
2009/3/30
The paper presents an unified approach to scheduling problems on ship-building lines based on discrete event-driven system theory.
以往，船舶上、下水是一项技术难度较大的操作，含有一定的风险。为了规避风险，船厂不得不投
巨资建造固定的机械化滑道，并延伸到水下。这种滑道的利用率低、占用场地的面积大，同时带来设备
折旧、维护成本高等不利因素，提高了修造船成本。而采用气囊的“柔性下水”工艺可简化船舶的下水、
上排过程，它无需固定滑道，不损伤船底油漆，具有投资省、效率高、安全可靠、机动灵活等优点。
