Experience and Challenges on Modeling and Simulation of Systems-of-Systems Software Architectures
Systems-of-Systems (SoS) software architectures are essentially challenging. SoS are composed of several constituent systems developed by different companies, complying with a high diversity of technologies and standards and linked by several different interoperability links. Arranging constituents to (i) form a feasible structure and (ii) accomplish complex behaviors is not a trivial task. In that sense, the adoption of simulation models can leverage Software Architecting for Systems-of-Systems (SASoS). Simulation models enable architects to predict, still at design-time, different architectural arrangements (coalitions) an SoS can assume at runtime as well as the feasibility of the behaviors delivered by each of the coalitions. While being a recognized practice in Systems Engineering, advances have been achieved in the last years to bring simulation models to SASoS practice. However, challenges still remain, such as (i) the use of simulation models to monitor and anticipate SoS behaviors at runtime, (ii) the use of simulation to predict, analyze, diagnose and measure SoS quality attributes, and (iii) precisely modeling SoS architectures to avoid failures that could lead to losses. This talk will provide the SESoS/WDES attendees with a tour over simulation model solutions for SASoS, particularly using DEVS formalism, besides presenting research opportunities that still remain.
Dr. Graciano Neto received his Ph.D. degree in computer science and computational mathematics from the Institute of Mathematical Sciences and Computation, University of São Paulo, Brazil and the Docteur degree in sciences and information technology from Université Bretagne-Sud, Lorient, France. Prof. Graciano Neto has been an Assistant Professor with the Institute of Informatics, Federal University of Goiás, Goiânia, Brazil since 2014. He has been involved in the publication of more than 80 peer-reviewed papers and articles, besides co-organizing scientific events, such as the Workshop on Modeling and Simulation of Software-Intensive Systems (MSSiS), Workshop on Blockchain-Based Software Architectures (BlockArch at ICSA) and a SoS Modeling Workshop at the I3M 2021 (International Multidisciplinary Modeling & Simulation Multiconference). Prof. Graciano Neto serves as a reviewer for important vehicles, such as SESoS/WDES, IEEE SoSE, Information and Software Technology and IEEE Computer, besides having 10-years teaching experience for technical high school, undergraduation, master’s and PhD levels. Prof. Graciano Neto interests include Systems-of-Systems, Software Architecture, Modeling & Simulation, Model-Driven Engineering and Information Systems. Dr. Graciano Neto is a member of the Brazilian Computer Society.
