Systems of Systems (SoS) are complex systems composed of managerially and operationally independent constituent systems (CS). Smart cities are examples of SoS. However, these types of systems impose challenges to traditional software architecture such as highly evolutionary architecture due to the evolution of individual CS and emergent behaviors that results from the interoperability of CS. Executable Models (ExM) are a class of models that can be executed and that can assist on architectural design of SoS. By using them, architects can predict the SoS structure and behavior by visualizing and simulating the SoS still at design-time. On the other hand, as any other emergent technologies, it suffers with absent scientific evidences of its benefits, mainly in industrial context. The main contribution of this master thesis project intends to be the presentation of evidences about the use of ExM to solve problems in the SoS software architecture design. For achieving such purpose, this project is structured in well-defined steps: (i) a systematic mapping study, (ii) elaboration of a conceptual map derived from the mapping study, (iii) a survey to obtain perceptions from software engineering professionals on the use of ExM in the context of engineering simple systems and (iv) a new survey expanding the previous study and to obtain perceptions from software engineering professionals on the use of ExM in the context of architectural design of SoS. Preliminary results reveal that ExM have been reported in diverse SoS domains, offering a dynamic and interactive view to the SoS. We also found that software engineering professionals see ExM as suitable solution for dealing with complex and critical systems as SoS.

Over the years, knowledge on how to engineer software-intensive system-of-systems (SoS) have been expanded and advanced. However, challenges still remain. Constituent Systems (CSs) are required to instantaneously connect themselves to a SoS while still preserving their own operational independence. Moreover, SoS CS are subject to a sort of heterogeneities that makes it difficult to make decisions outside predefined frameworks, environment and hierarchical command-control structures. Hence, many of the systems currently available are not prepared to be part of an SoS, i.e., they can not maintain their operational independence despite their participation in one or more SoS. Based on this context, the main goal of this research is to exploit how to design a software architecture for systems that are intended to become part of a SoS in the future. To achieve this goal, we chose the urban mobility SoS domain, and then executed a software architecture design process to design a software architecture for an autonomous car as CS of this SoS. Later, we evaluated it through simulation. Preliminary results reveal that our proposal comply with the requirements raised during the architectural design process and can enable a system to be a constituent of a SoS while still preserving its operational independence.
