Continuous Systems and Software Engineering for Industry 4.0: A disruptive view

Context: Industry 4.0 has substantially changed the manufacturing processes, leading to smart factories with full digitalization, intelligence, and dynamic production. The need for rigorous and continuous development of highly networked software-intensive Industry 4.0 systems entails great challenges. Hence, Industry 4.0 requires new ways to develop, operate, and evolve these systems accordingly. Objective: We introduce the view of Continuous Systems and Software Engineering for Industry 4.0 (CSSE I4.0). Method: Based on our research and industrial projects, we propose this novel view and its core elements, including continuous twinning, which is also introduced first in this paper. We also discuss the existing industrial engagement and research that could leverage this view for practical application. Results: There are still several open issues, so we highlight the most urgent perspectives for future work. Conclusions: A disruptive view on how to engineer Industry 4.0 systems must be established to pave the way for the realization of the fourth industrial revolution.
