Abstract: Complex forming equipment is the foundation of high-end manufacturing industry, and it is an important guarantee for the industrial upgrading and the technological progress. The rapid developing information technologies, such as Internet and Big data, have become an indispensable part of the equipment manufacturing industry. The design and optimization of the complex forming equipment's product architecture with service-oriented is studied. Through the analysis of characteristics of design architectures of complex forming equipment in the Internet and Big data era, a framework of product architecture is established as the corresponding relationships between the requirement domain, the function domain and the architecture domain. Thus, the product-service modeling methods and integration framework of complex forming equipment based on QFD and DSM are proposed. The modularization optimization method is also developed with the consideration of the operation costs.

Key words: service, complex forming equipment, the design and optimization of product architecture, quality function deployment
