摘要：The framework for supporting conceptual design using case-based reasoning is studied. Adesign knowledge representation scheme is presented. It is capable of representing both generalized and specific design knowledge. A two-phase case retrieval strategy, called index elaboration, is described which supports both requirement-function transformation and function-feature transformation at conceptual design stage. We propose a prototype system and discuss in detail the realization of supporting conceptual design by CBR.

摘要：针对三维场景建模缺乏领域含义的问题,提出一种基于语义的三维场景概念关系建模方法。该方法提出一种基于语义的三维场景模型,并结合约束设计和元素间关系的语义描述方法,来阐述如何丰富三维场景的领域含义。最后结合原型系统和实例对该方法进行了可行性和合理性的验证。
