摘　　要：提出了一种应用于产品变型设计中的本体筛检方法,该方法以完整的产品资源本体视图为基础,将产品的功能需求、结构特征等转化为需求约束,设计人员根据需求约束对产品资源本体进行筛检。针对不同的筛检层次和筛检对象,给出了模式匹配、实例匹配与人工决策相结合、实例推理自动匹配等筛检规则。这种人机结合的半自动筛检方法提高了产品变型设计方案的准确性,增加了设计过程的柔性和效率。开发了一套针对建筑门窗产品的变型设计支持系统,证明所述方法的可行性和有效性。A product ontology screening method which can be used in variant design is proposed. With the support of complete ontology view of product resources, the product functional requirement and structural characteristics are converted to demand constraints, which are used to screen product ontology. For different screening hierarchies and objects, different screening rules such as pattern matching, case matching combined with manual decision and auto matching on the basis of case-based reasoning are adopted. The semi-automatic screening method with human-computer cooperation has impressive effectiveness on the improvements of the accuracy of design schemes and the flexibility and efficiency of design process. Finally, a variant design supporting system for building door and window is developed, which proves the feasibility and effectiveness of the method.
