语义特征建模系统中概念设计方案表示研究

摘要

To improve the efficiency and level of conceptual design, a semantic representation based method is proposed. It represents features of model by semantic representation, manages data of model by cellular model, transforms conceptual design scheme to black boxes which have n input and m output semantics by semantic faces of features, creates relations between production model and features with semantic dependent graph, and simplifies reasoning process of conceptual design scheme by force transmission method. This method can not only improve the solving speed of conceptual design, but also provide more abundant schemes. Experiments show that this new algorithm is more adaptable and practical.%为了提高概念设计的工作效率和设计水平,提出了一种基于语义表示法的概念设计方案的表示方法.这种方法通过语义表示法来表示模型中的特征,通过细胞元模型来管理模型数据,通过语义面将特征和设计方案表示成为具有n个语义输入和m个语义输出的黑盒,通过语义依赖图建立产品模型与特征之间的组织关系,通过力传递的方法来简化概念设计方案的推理过程.该方法不仅可以大大提高概念设计问题的求解速度,还可以为设计者提供更丰富的概念设计方案.实验证明该算法具有广泛的应用前景和实用价值.
