面向设计重用的设计理性模型变换方法

摘要

在设计理性建模的基础上研究设计理性模型的不同抽象层次的变换方法.该方法包括应用基于Web本体语言的知识推理实现设计理性模型片段划分、设计理性模型主脉络抽取等关键步骤,从而建立不同抽象层次的设计理性模型,优化设计理性模型知识表达形式及表达能力,为设计理性重用提供更有力的支撑.开发了设计理性建模与变换原型系统,并以压弯模具设计为例,验证了设计理性模型变换方法的可行性及有效性.%Based on the modeling of Design Rationale (DR),the variable-granularity transformation methods for DR model's different abstraction level were researched.In this method,the key steps such as DR model partition by OWL-based knowledge reasoning and the main thread extraction of DR context were included.Thus the DR models with different abstractions were constructed to optimize the DR model in its knowledge expression form and knowledge expression ability.It would provide strong support for DR reuse.A prototype system was developed for DR modeling and transformation,and the design process of bending die was taken as an example to validate the feasibility and effectiveness of the proposed methods.
