Optimum design of mixed discrete variables of engineering structure

针对设计变量为离散型和连续型的混合离散变量的优化设计问题 ,探讨了非均匀离散变量及连续变量的均匀离散化处理方法 ,分析了求解混合离散变量的优化设计问题最优解的方法。算例表明混合离散变量的优化设计方法可以应用于工程结构优化设计中 ,其优化结果不需圆整 。

This paper discusses the optimal solution to the optimization design of mixed discrete variables after providing the solution to uniform discrete of non-uniform discrete variables and continuous variables with the focus on the optimization design of discrete and continuous variables. The example shows that the optimum design method of mixed discrete variables can be applied to the optimization design of engineering structure. The optimal results needn't be approximated. The efficiency and reliability of optimum design are improved.
