摘要
应用线性优化的方法给出了集装箱重量分布的优化模型和求解方法 .通过集装箱船弯矩最小求得在一定货源条件下集装箱重量在船上的纵向最优分布 ,通过使集装箱船初稳性高度 GM接近最优目标值求得集装箱重量的垂向最优分布 .在此基础上提出了一种求取集装箱船最优初稳性高度GM* 的简便方法 ,该方法假定 GM* 主要与船宽、航次所经航区的风浪和甲板上浪的容易程度有关 .最后提出一种通过在预定压载方案下求取稳性范围 ,并通过调整压载使初稳性高度上限值接近且略大于 GM*
In this paper, a model and a solution about weight distribution of containers on board are given by using linear programming. The optimization method is to obtain optimal vertical and longitudinal distribution of containers in weight by minimizing the bending moment and the stability respectively. A simple method of getting an optimized value of initial stability is provided based on analysis on the demand of stability about container ships. It assumes that the optimal stability is rested with the ship's breadth, weather and the amount of sea water on deck. At the end of this paper, a method of finding the least quantity of ballast water is offered.
