Abstract: 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 with α-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 and α**-algorithm was identified.The intentional tree was derived as XES file to generate design process model with α-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.

Key words: design rationale, design intention, α-algorithm, design process mining
