Abstract: To reduce iteration and maintenance time of Digital Twin (DT) systems and lower evolution costs, the potential of integrating the DevOps (Development and Operations) methodology into DT systems was explored in this study, and an innovative DT system development and operations practice — DTOps (DT Operations) was proposed. A service-oriented system architecture was designed for the specific needs and characteristics of DT systems, enhancing system's scalability and agility, and the primary infrastructure of DTOps as well as the implementation methods of continuous integration and continuous delivery were provided. In a case study of a gear production line, various stages of DTOps were validated using open-source tools, demonstrating its feasibility and convenience. Comparative experimental results show that DTOps improves evolution efficiency by 29.7% and 26.9% compared to monolithic and microservice architectures, respectively. This effect is particularly pronounced in highly integrated and data-intensive environments, confirming its effectiveness in engineering applications.
