Abstract Modularization is a method to simplify complex product systems. Modular production was originated in the machinery industry to reduce the complexity of a product system, and then widely used in the information technology industry and manufacturing industry. Modular production network is the result of intra-product division under economic globalization. The information governance in modular production network includes both personal information encapsulation and system information assimilation. This enhances the innovative capability and anti-risk ability in modular production networks.
