基于设计理性模型的设计过程知识挖掘

Design process knowledge mining based on design rationale models

针对当前设计理性模型的重用主要集中于检索和浏览而缺乏对模型本身进行深度挖掘这一问题,结合流程挖掘领域的α算法提出给予设计理性模型的设计过程挖掘方法,生成设计过程模型以指导设计者高效完成设计工作。首先通过意图树提取算法消除设计理性模型中的循环、迭代环节生成简洁的设计意图树,然后基于相似度计算和α**算法识别设计意图树中的相同意图和重复意图,最后将设计意图树导出为XES文件,通过α算法挖掘产生设计过程模型。以自动打标机的设计理性模型为例验证了所提方法的可行性和有效性。

Aiming at the problem that the current reuse of design rationale model was focusing on the retrieval and browse,which lacked in deep mining of model itself,a design process mining approach associated withα-algorithm in process mining was proposed to generate design process model and guide designer to finish the design effectively.The loop and iterative steps in design rationale model were eliminated by using intentional tree extracting algorithm.The similar and repeat intentions based on similarity calculation andα**-algorithm was identified.The intentional tree was derived as XES file to generate design process model withα-algorithm.A design rationale model of an automatic marking machine was used as an example to demonstrate the feasibility and effectiveness of the proposed method.
