摘要
基于海洋工程中存在的设计变量为离散型和连续型的混合离散变量的情况,探讨了一种优化设计问题的方法———混合离散模拟退火法.该方法相对常规模拟退火方法有一定改进并且针对混合离散变量进行了特定处理.实际算例计算表明,该方法可用于海洋工程优化设计中,其结果不需圆整,而且其解题可靠性和效率相当高.
In this paper an optimum design method, the annealing simulation method for hybrid discrete variables （ASFHDV）, is discussed with the focus on the optimization design problem with discrete and continuous variables in ocean engineering. In comparison with the general annealing simulation method, the method discussed in this paper is greatly improved and some special steps are adopted to deal with the hybrid discrete variables. The results of some practical computational examples show that the method ASFHDV is highly effective. ASFHDV can be used in the optimum design of ocean engineering; and the results need not be approximated by ＂round method＂. The method ASFHDV can solve optimum problems with quite good reliability and high efficiency.
