自動車生産でのモジュール化の検討

抄録

Modularity is a technique to separate the inner structures and the interface among them by setting uparchitecture in the relationships among modules that are the constitutional units of a machine. Interfacestipulates in detail how modules interact, how they are placed (or connected), and how they exchangeinformation. By disclosing the interface the supplier can maintain specialty and differentiation and hencethe supplier can take an advantage over the users since the users must rely on them. The source of acomplex system is the complex interactions among many parts. Knowledge about a system is a complexknowledge system that involves subsystem selection to be combined and the logic that works behind thesystem, which is an implicit knowledge that is difficult to formalize and transfer. The knowledge systemis indispensible for product development projects. Modularity is considers to be inadequate forautomobiles, which need the integrity of whole product, however, modularity of core parts such ashybrid systems has been under way in Japanese companies.
