A novel digital factory technology in complex production application

In order to promoting products development period and improving production quality, all enterprises have found the digital factory is a good comprehensive solution approach. However, for complex products, there is still lack of open integration possibilities among products and production manufacturing process modeling, simulation, analyzing, visualizing and optimizing systems tools on a multi criteria level. This paper investigates a systematic approach NPU-EDASP (Enterprise-level Digital fActory and its production system Simulation Platform developed by Northwestern Polytechnical University) which adopted service-oriented development methodology and top-down design mode to design the entire architecture. In particular, it utilizes four key technologies and methods to bridge the gape exits among products and production manufacturing process modeling, simulation and analyzing. Using this platform, users can optimize material flow, resource utilization and logistics in large enterprise for the complex products and production engineering processes. A case study of a successful model demonstrates that the NPU-EDASP digital factory offers an integrated approach to enhance products and production engineering.
