本文讨论了具有连接离散变量的结构优化设计问题。对于此类应用程序，当为变量选择离散值时，还必须从表中选择链接到该变量的其他变量的值。利用现有截面进行钢结构设计是此类问题的一个主要应用领域。提出了三种策略，即联合收割机连续变量优化方法与遗传算法相结合，模拟退火，和分支和界限法，并实现到计算机程序的数值评估。解决了三个结构设计问题，研究所提出的方法的性能。求解离散变量问题的CPU时间很长。提出了减少这些时间的策略。
The problem of optimal structural design having linked discrete variables is addressed. For such applications, when a discrete value for a variable is selected, values for other variables linked to it must also be selected from a table. The design of steel structures using available sections is a major application area of such problems. Three strategies that combine a continuous variable optimization method with a genetic algorithm, simulated annealing, and branch and bound method are presented and implemented into a computer program for their numerical evaluation. Three structural design problems are solved to study the performance of the proposed methods. CPU times for solution of the problems with discrete variables are large. Strategies are suggested to reduce these times.
