“…The set of design parameters necessary or relevant for a certain system design is thus variable and not a constant full set P in such cases. Describing such problem types requires models that go well beyond a vector of numerical values of design parameters [24], [25], [7], [8].…”

Finding a good solution to an engineering problem under given constraints can be formulated as an optimization problem over a set of parameters. Existing (semi-)automatic methodologies for this task usually assume that these design parameters form a homogeneous set. The paper analyses the structure of design space and introduces the formal concept of existence-dependent parameters, which appear for instance in the optimization of system architectures. The corresponding nested optimization problems can be solved more efficiently considering the dependency relations, and will often require a mix of models and optimization algorithms. The paper proposes a completely model-driven integration methodology for such problems and a prototype tool combining several existing domain-specific tools. An application example from the area of distributed embedded systems design of hardware architecture and software mapping demonstrates the applicability.

“…Another possible way of realizing this persistent kind of tokens is explained in the next section. Figure 6 shows a simplified version of an optimization loop, similar to the one proposed in (Wichmann, Jäger, Jungebloud, Maschotta, and Zimmermann 2016). The loop realized with a chain of different call operation actions.…”

“…This is done by introducing additional constraints, extensions to existing components, and the use of additional UML elements to reduce the total number of components needed. This work has been motivated by the model-based specification of executable models for optimization heuristics, when necessary control structures were hard to specify with the set of available elements (Wichmann et al 2016). The methodology consists in enriching an existing execution engine for C++ and a model generation process realized with the Eclipse component Acceleo by specifying additional UML elements that do not belong to the fUML subset.…”

The fUML allows creating models by using a subset of UML diagram elements. This approach has the benefit of keeping the execution engine simple, but it is sometimes limiting, as it does not permit to specify certain advanced constructs such as loops in a concise way. This paper shows and discusses some of these constructs and introduces additional component specifications or modifications to existing ones to reduce the number of elements needed to realize a model. The methodology consists in enriching an existing execution engine for C ++ by specifying additional UML items that do not belong to the fUML subset. The execution engine allows the execution of diagrams that model complex structures with less overhead leading to models which are easier to realize and maintain. Moreover, the model-driven execution engine allows supporting those additional elements without impairing the reached level of conformance.

“…An indirect optimization approach is realized using an approach of model-based specification of executable system optimization processes based on activity diagrams in our previous work (Wichmann et al 2016). UML class diagrams and activity diagrams (OMG 2013b) are used to model structure and behavior of optimization processes of a system, which should be integrated into C++-based applications.…”

Deriving Architecture Design Variants for System Optimization From Design Space Descriptions Expressed using a UML Profile

In complex (dynamic) systems, models are usually too complex for a direct evaluation, and simulation is the method of choice (indirect optimization). Another aspect is the structure of the design space for complex system. In a recent paper of the authors, an approach is presented for design space description with a UML profile-based description of architectural variations of complex dynamic systems. In order to execute a simulation of a system variant, one has to be chosen based on the used heuristic, and specified in a standardized way to be used for constructing the actual simulation model with the use of a library of template models. This paper approaches a method to automatically generated individual UML object models from the design space specification for a given parameter selection.
