Abstract
A fundamental concept of DMCM (Design and Manufacturing Communication Model) is proposed. This concept is to represent a design and manufacturing process as a communication activity. An abstractive “process” is introduced as a key concept of the DMCM that represents an information communication between objects. The object is represented as a communication target, and its inner activity is not treated. To accomplish this concept, a resource structure is proposed as a framework to construct a design and manufacturing communication model. In this framework, the model is constructed with a resource that represents several data communication target and communication process. A formal specification language EPDL (Engineering Process Description Language) is proposed. As an example, a design modification work is described.
