Requirements Engineering and Simulation for System of Systems Integration: A Systematic Literature Review

Context: The integration of systems in Systems of Systems (SoS) environments represents a growing challenge, especially due to the complexity of managing interoperability requirements in distributed and emergent contexts. Objectives: This systematic review identifies, analyzes, and synthesizes existing approaches for requirements management in SoS integration processes with a focus on simulation. Methods: The Scopus, Web of Science, and IEEE Xplore databases were consulted. The search, conducted between 2015 and 2025, returned 144 records. After removing duplicates and applying eligibility criteria, 20 studies were included. Methodological quality was assessed using a customized checklist.
