摘要
动力定位能力评估在动力定位系统设计中有着重要的作用。它从数学本质上看就是带约束的非线性最优化问题,而模拟退火算法是解决这类问题较为有效的方法。文章介绍了模拟退火算法在动力定位能力评估中的应用,对实例进行了控位能力计算,并将计算结果与Kongsberg公司计算结果进行比较。分析表明,基于模拟退火算法开发的动力定位能力评估方法是可靠的,能更好地满足力以及力矩平衡的要求。
Dynamic positioning (DP) capability analysis plays a very important part in DP system design. Mathematically, it is a typical nonlinear constraint optimization problem. Simulated annealing algorithm (SAA) is an effective way in solving this kind of problems. In this paper, SAA is utilized in DP capability analysis. And two vessels' capability is evaluated as example. The results meet well with Kongsberg's report, and show that DP capability analysis based on SAA is reliable and successful.
