The level of virtual technology we can achieve largely affects the maneuverability of the digital factories system, and it also affects the correctness of the users judgments to the product design as well as the producing process.

27 Key Technologies of Digital Factory Optimization simulation technology: The Optimization simulation technology is all about analyzing all kinds of potential problems and optimizing programs that may occur during the process of the virtual producing according to the built digital models and the simulated results from the simulating system and other predicted data. When it comes to whether can mostly exert enterprise s benefit and improve enterprise s competitiveness, the level of this optimizing simulation technology is vital.

28 Key Technologies of Digital Factory Application production technology: As the need of the producing automation, digital factories systems is expected to offer all sorts of controlling programs that can be directly applied in the actual producing equipment and all kinds of processes and report files which could be needed. All kinds of friendly and excellent application interface could accelerate the transforming process from digital design to actual producing application.
