                         (CoPS) requires in-depth knowledge of technology and the system 
                         integration process. Technology Readiness Assessment (TRA) is a 
                         systematic evidence-based process that assesses technology 
                         maturity based on Technology Readiness Levels (TRL). System 
                         Readiness Assessment (SRA) is the process of conducting integrated 
                         assessments of a developing system to assess technology maturation 
                         and provide a systemic understanding of the development 
                         life-cycle. The Integration Readiness Levels (IRL) scale 
                         complements TRL in representing integration between technological 
                         elements in a system, and both scales are used in SRA to calculate 
                         system readiness metrics. SRA is expected to be an emerging 
                         systems engineering best practice and has evolved over the last 
                         decade. However, SRA does not explicitly guide whether simulation 
                         could comply with IRL dedicated to interface verification and 
                         validation. Modeling and simulation (M\&S) play many roles in 
                         systems engineering. Digital and M\&S technologies advancement, 
                         as Model-Based System Engineering (MBSE) and digital twins, may 
                         contribute to reducing space missions' costs and schedule, along 
                         with trends in systems and technology reuse. This research 
                         identified the possible roles of modeling and simulation in 
                         assessing spacecraft Integration Readiness Levels. Results showed 
                         M\&S possible roles for each IRL and whether the roles were 
                         essential or support to achieve IRL. Also, a link between system 
                         life cycle processes and these results contributes to the SRA 
                         research stream. A case study with the China-Brazil Earth 
                         Resources Satellite (CBERS) program was used to validate part of 
                         the proposed theory, in line with other cases extracted from the 
                         literature. This paper contributes to the SRA research stream with 
                         these theoretical and practical results, by suggesting future 
                         studies that could improve SRA practice and consequently support 
                         the decision-making on technology introduction in CoPS.",
