| 摘 要： | 针对概念设计中对应功能的结构选择的多样性,利用组合优化思想进行了定量求解。根据产品功能与结构、结构与结构之间的相互关系,定义产品的相关矩阵,建立产品结构概念设计的多目标优化数学模型。对产品的功能、行为和结构等各种设计因素,给出了统一的设计因素基因表达的定义。对最优保存简单遗传算法进行改进,给出选择最优结构的数学计算过程。实例分析表明采用这种方法能够实现最优结构选择的自动化设计,并且这种改进的遗传算法能够获得很好的在线性能与离线性能。

| Abstract: | Selecting optimization structure is the key problem of the researchers in the fields of conceptual design. According to the relationships between structure and function, the mathematical models of multi-object optimization structure design are provided. Some concepts about gene expression and correlation matrix are defined. An improved genetic algorithm called segmenting genetic algorithm is proposed. An example is given to show that this method is able to realize the automatic design of selecting optimization structure. In addition, this segmenting genetic algorithm can provide good on-line and off-line performances. |
