“…In this sense, SoIS can support inter-organization business processes, making this class of systems to have a strong business-oriented nature. This raises the need of establishing representation and management strategies to support concepts such as sequence of activities and interdependence between roles and goals [5], [10].…”

Systems-of-Information Systems (SoIS) are a class of systems-of-systems (SoS) in which constituents are information systems and exhibit a strong business-oriented nature. Existing mission notations and approaches for specifying missions in SoIS have not been able to cope with particular characteristics of this class of systems, including the sequence and interdependence among activities, roles definition, and the dynamics of constituents to freely join or leave a SoIS. In this context, we claim that Business Processes Modeling (BPM) techniques and models could complement such approaches, offering support for requirements specification and an additional viewpoint for architectural specification of SoIS. This position paper outlines a discussion on the potential of BPM to complement mission specification modeling notations, as well as it presents some research directions and challenges for modeling missions in SoIS.

“…Each transition in an atomic model can work as a test case, and data can be provided by external files that hold test cases that are automatically generated by a testing tool [74,75]. Moreover, VV&T for SoS is currently a challenging research issue and point of investigation in software engineering for SoS [43].…”

“…Moreover, a recent study reveals that MBE has been adopted for the development of SoS (around 60% of included studies in a systematic mapping applied MBE for development of SoS [43]). MBE has been applied in SoS context for managing systems complexity, developing candidate architectures, and verifying design decisions early in the development process.…”

Background: Systems-of-systems (SoS) are alliances of independent and interoperable software-intensive systems. SoS often support critical domains, being required to exhibit a reliable operation, specially because people's safety relies on their services. In this direction, simulations enable the validation of different operational scenarios in a controlled environment, allowing a benchmarking of its response as well as revealing possible breaches that could lead to failures. However, simulations are traditionally manual, demanding a high level of human intervention, being costly and error-prone. A stimuli generator could aid in by continuously providing data to trigger a SoS simulation and maintaining its operation. Methods: We established a model-based approach termed Stimuli-SoS to support the creation of stimuli generators to be used in SoS simulations. Stimuli-SoS uses software architecture descriptions for automating the creation of such generators. Specifically, this approach transforms SoSADL, a formal architectural description language for SoS, into dynamic models expressed in DEVS, a simulation formalism. We carried out a case study in which Stimuli-SoS was used to automatically produce stimuli generators for a simulation of a flood monitoring SoS. Results:We run simulations of a SoS architectural configuration with 69 constituent systems, i.e., 42 sensors, 9 crowdsourcing systems, and 18 drones. Stimuli generators were automatically generated for each type of constituent. These stimuli generators were capable of receiving the input data from the database and generating the expected stimuli for the constituents, allowing to simulate constituent systems interoperations into the flood monitoring SoS. Using Stimuli-SoS, we simulated 38 days of flood monitoring in little more than 6 h. Stimuli generators correctly forwarded data to the simulation, which was able to reproduce 29 flood alerts triggered by the SoS during a flooding event. In particular, Stimuli-SoS is almost 65 times more productive than a manual approach to producing data for the same type of simulation. Conclusions: Our approach succeeded in automatically deriving a functional stimuli generator that can reproduce environmental conditions for simulating a SoS. In particular, we presented new contributions regarding productivity and automation for the use of a model-based approach in SoS engineering.

“…Para caracterizar o estado da arte da relação entre arquitetura de software e teste de software, foi conduzido um mapeamento sistemático da literatura (SOUZA et al, 2016;SOUZA et al, 2017b;SOUZA et al, 2017a). Nesse, foi evidenciado que o teste baseado em arquitetura é a principal abordagem para relacionar arquitetura de software e teste de software.…”
