摘　　要：本文提出了由有限元系统组成的结构组合优化设计的多阶段决策算子方法;以含梁单元的平面刚架结构与弹性薄板结构组合优化设计为例说明了方法的应用。由于这个方法具有通用性好、公式推导和程序简单,节省计算机存储等优点,它可在工程设计领域中广泛应用。This paper presents a multistage decision operator method for structural combinatorial optimization of finite element systems. By using the method, the optimum design problem of plane frame consisting of beam-containing element and the optimum design problem of elastic thin plate are discussed and solved successfully. Because the method possesses the features of good common use, simple formulation and programming, saving computing time and samll storage needs of the computer, it can be widely applied in the engineering design.
