RESUMO:

Missions represent a key concern in the development of systems-of-systems (SoS) since they can be related to both capabilities of constituent systems and interactions among these systems that contribute to the accomplishment of global goals of the SoS. For this reason, mission models are promising starting points to the SoS development process and they can be used as a basis for the specification, validation and verification of SoS architectural models. Specifying, validating and verifying architectural models for SoS are difficult tasks compared to usual systems, the inner complexity of this kind of systems relies especially on the emergent behaviors, i.e. features that emerge from the cooperation between the constituent parts of the SoS that often cannot be accurately predicted.

This work is concerned with such a synergetic relationship between mission and architectural models, giving a special attention to the emergent behavior that arise for a given configuration of the SoS. We propose a development process for architectural modeling of SoS, centered in the so-called mission models. In this proposal, the mission model is used to both derive, validate/verify architectures of SoS. In a first moment we dene a formal mission model, then we generate the structural definition for the architecture using model transformation. Later, as the architect specify the behavioral aspects of the system, using this architecture, we can generate concrete architectures that will be verified and validated using simulation-based approaches. The verification uses statistical model checking to verify whether the properties are satisfied, within a degree of confidence. The validation is aimed to emergent behaviors and missions, but can be extended to any aspect of the mission model. The simulation also allows the identification of unpredicted emergent behaviors. A toolset that integrates existing tools and implements the whole process is also presented.
