複合システムの設計プロセス管理のためのマルチドメインDSM手法

抄録

Design of a complicated system is performed through collaboration of multiple domains, such as mechanical engineering, software engineering and control engineering. Its process is based on dependencies between elements of the product system, which is often differently perceived in each domain even if they have a common understanding of system elements. A design manager should coordinate the understanding gap among multiple domains. Although DSM (Design Structure Matrix) is an effective modeling method for properly planning design process focusing on dependency, it lacks facility for the coordination. This research proposes a new method called Multi-Domain DSM (MDDSM) to clarify differences of designers' understanding about dependencies in each domain, and coordinate them. MDDSM assumes a designer describes DSM based on his/her expertise. MDDSM provides a method to define reliability of dependency description according to the degree of designer's expertise of the corresponding system elements. If different designers state different dependency description, the reliability definition helps to decide which designer's description should be prioritized. It can support to sophisticatedly integrate variations of DSM description of multiple domains. A proposed method is applied to design process of a mechatronic product in order to verify its ability.
