| 摘 要： | 本文把模拟退火（SA）法应用于舶舶主尺度优化问题中。针对船舶主尺度优化问题解的特性和状态，对SA算法具体应用中的几个问题进行了探讨。同时，与单纯形法进行了优化结果的比较。比较表明，SA算法能很好地逃离局部极值点的陷阱找到全局最优解，其优化结果与初始点的选择无关，从而为船舶主尺度优化问题提供了一种稳定可靠的全局最优化算法。

| Abstract: | This paper applies the Simulated Annealing (SA) Algorithm to the global optimization of ship main dimensions. In accordance with the characteristics and conditions of the solution of ship main dimension optimization, the paper discusses several problems in the application of SA algorithm and at the same time makes a comparison between SA algorithm and simplicity approach. The comparison shows that the SA algorithm could avoid the local extreme point and find the global optimal solution, the result of which has no relation to the choice of initial point. Thus a stable and reliable global optimal algorithm could be provided for the problems of ship main dimension optimization. |
