“…Hence, goals of the individual systems and goals of the overall system network should be explicitly distinguished in modelbased manner [8] in order to monitor the adaptation of system behavior using, for example, a MAPE-K feedback control loop [47]. Hence, by contrast in [10], we proposed an approach for explicitly modeling these different goals and their relationships through clearly separating the individual systems and the overall CPS network.…”

Collaborative systems such as cyber-physical systems (CPS) dynamically form runtime networks to achieve goals that cannot be achieved by the individual system alone. While much research has been done on architectures for adaptive systems, these approaches do not consider the fact that goals exist on network level and thus need specific adaptation strategies. In decentralized settings where there is no central mechanism for orchestrating and coordinating the collaboration between systems, failure to adapt individual systems' behaviors without considering the network's overall outcome may result in a functional degradation of the entire network, possibly to the point of injuring humans and harming individual systems in the network. In this article, we propose a goal-based adaptation approach that takes the goals of the individual systems as well as the goals of the overall network into account. Our approach allows considering adaptation strategies based on the network goals which are fulfilled by automated behavioral adaptations of the individual system of the network. Results from a proof-of-concept application to an industrial case example show applicability and usefulness of the approach.

“…This allows for starting with quite informal requirements that are very close to the originating stakeholders' ideas and refine them into more fine-grained detailed requirements. In the training program, we use the ITU Goal oriented Requirements Language (GRL) [23] to document goals as it has already proven useful in industrial settings [24]. GRL is a language to hierarchically structure goals and to define dependencies between them.…”

The use of conceptual models to foster requirements engineering has been proposed and evaluated as beneficial for several decades. For instance, goal-oriented requirements engineering or the specification of scenarios are commonly done using conceptual models. Bringing such model-based requirements engineering approaches into industrial practice typically requires industrial training. In this paper, we report lessons learned from a training program for teaching industry professionals modelbased requirements engineering. Particularly, we as educators and learners report experiences from designing the training program, conducting the actual training, and applying the instructed material in our day-to-day work. From these findings we provide guidelines for educators designing requirements engineering courses for industry professionals.

Which aims at transferring research results from its predecessor projects SPES and SPES XT http://spes2020.informatik.tu-muenchen.de into industrial practice.

“…GRL is discussed further here because this is the only internationally standardized goal modeling language so far and one of the few languages that supports indicators, which enable monitoring in an adaptive context. GRL has also been used in the modeling and design of large CPSs, some with a social aspect but without adaptation (e.g., for collaborative CPSs [29]), some that adapt but without a social aspect (e.g., for unmanned aircraft systems [30]), and some that model adaptive SCPSs (e.g., for smart homes [31]).…”

Background: Socio-cyber-physical systems (SCPSs) are a type of cyber-physical systems with social concerns. Many SCPSs, such as smart homes, must be able to adapt to reach an optimal symbiosis with users and their contexts. The Systems Modeling Language (SysML) is frequently used to specify ordinary CPSs, whereas goal modeling is a requirements engineering approach used to describe and reason about social concerns. Objective: This paper aims to assess existing modeling techniques that support adaptation in SCPSs, and in particular those that integrate SysML with goal modeling. Method: A systematic literature review presents the main contributions of 52 English articles selected from five databases that use both SysML and goal models (17 techniques), SysML models only (11 techniques), or goal models only (8 techniques) for analysis and self-adaptation. Result: Existing techniques have provided increasingly better modeling support for adaptation in a SCPS context, but overall analysis support remains weak. The techniques that combine SysML and goal modeling offer interesting benefits by tracing goals to SysML (requirements) diagrams and influencing the generation of predefined adaptation strategies for expected contexts, but few target adaptation explicitly and most still suffer from a partial coverage of important goal modeling concepts and of traceability management issues.
