Abstract
This paper discusses a digital design and manufacturing system model for agile development and production. For the last few decades, virtual design tools for CAD/CAM, simulator and flexible production equipment such as 3D scanner, 3D printer, NC processing and assembly machine has been realized. Traditional manufacturing enterprises can not respond to changing personal demands and community demands while they can overproduce the commodities. Therefore new type of enterprise models is required. An open and agile model that is based on both iterative development method using time box for the project management and virtual manufacturing is proposed. First, the definitions for the frames are given then the four layer structure model is explained.
