摘要
以维修舱空间、舱室邻接、舱室全局位置三个指标为目标函数,以满足高初稳性要求、保证船舶浮态等为约束条件,建立技术可行前提下半潜维修船功能舱室布局优化模型。通过设计贪婪取走启发式算法与规划求解相结合的两阶段算法,实现对模型的求解。以载重为5×10^4 t的半潜船体为载体进行设计,得到半潜维修船功能舱室优化布局方案。随着维修设备质量系数的增加,可行的布局方案数呈上升趋势。该方法可提高半潜维修船在功能舱室布局过程中决策的科学性。
A layout optimization model about functional tanks in semi-submersible repair vessels was established under the premise that relevant technologies can be reached.The objective function of this model was put forward under the consideration of three factors about maintenance and repair tanks,such as tank size,tank adjacency,and tank global position.The constraints of this model were set to meet initial metacentric height requirement and guarantee to float on even keel.This optimization model was solved by a two-stage algorithm of combining greedy dropping heuristic algorithm with programming solve.The functional tanks layout solution was obtained with the aid of a semi-submersible hull whose capacity reaches the level of 50 000 tons.This testified the rationality of this model and practicability of this algorithm.And the number of feasible layout solutions shows an upward trend with the increase of the maintenance equipment weight coefficient.This method can improve scientificity in decision-making process about functional tanks′layout in semi-submersible repair vessels.
