再利用性を指向した設計論理の構造化の検討

抄録

As products become large-scale and complex, manufacturing industry faces problems in communication between workers. Among the information to be communicated, design rationale, such as reasons for decided design and the process of consideration leading to the decisions, is rarely expressed in shared design data. One of the reasons for this is that there is no defined structuring method for the design rationale, such as CAD. In this study, two approaches were used to structure the design rationale toward reusability. The first is that the design rationale is captured in a dynamic model of the design process and a static model of the design object. Modelling the entity and function that is the object of the design operation can be used when selecting what to refer to from the stored design rationales. The second is an extension of DRed(Design Rationale editor), one of the design structuring methods. DRed captures the rationale for the evaluation of design proposals but does not capture the rationale for the ideation of design proposals. However, this study considered that both the ideation and evaluation of design proposals should be recorded. Because the rationale for ideation needs to store for data, assuming that intelligent CAD and generative AI will be able to perform automated design in the future. The proposed model reflecting the two approaches was developed. In this paper, the model is used in a design experiment and a discussion of the result is presented.
