Software and Systems Modeling (SoSyM)

Developing distributed real-time systems is a complex task that has historically entailed specialized handcraft. In this paper, we propose a retrospective on the (r)evolutionary changes that led to the transition from low-level programming to ...

Process models are important for supporting organizations in documenting, understanding and monitoring their business. When these process models become outdated, they need to be revised to accurately describe the new status quo of the processes in ...

It is well-known that the satisfiability problem of feature diagrams (FDs) is computationally hard. This paper examines the complexities of the satisfiability problems of sixteen FD sublanguages, i.e., languages that only permit a subset of the ...

The need for real-time collaborative solutions in model-driven engineering has been increasing over the past years. Conflict-free replicated data types (CRDT) provide scalable and robust replication mechanisms that align well with the requirements ...

Models based on differential programming, like deep neural networks, are well established in research and able to outperform manually coded counterparts in many applications. Today, there is a rising interest to introduce this flexible modeling to ...

To assure certain critical quality properties (e.g., safety, security, or privacy), supervisory authorities and industrial associations provide reference frameworks such as standards or guidelines that in some cases are enforced (e.g., regulations)...

Domain-specific languages allow engineers and domain experts to express problems and design solutions using domain-focused vocabularies and abstractions, by means of graphical or textual syntaxes. In the case of textual syntaxes, language ...

Structured query language (SQL) is a widely used language for accessing both relational and non-relational databases. SQL is the standard form of access in relational databases, while in non-relational databases, SQL is becoming increasingly ...

Nowadays, large-scale software systems in many domains, such as smart cities, involve multiple parties whose privacy policies may conflict with each other, and thus, data privacy violations may arise even without users being aware of it. In this ...

Optimization problems in software engineering typically deal with structures as they occur in the design and maintenance of software systems. In model-driven optimization (MDO), domain-specific models are used to represent these structures while ...

Recent results in language engineering simplify the development of tool-supported executable domain-specific modeling languages (xDSMLs), including editing (e.g., completion and error checking) and execution analysis tools (e.g., debugging, ...

The COVID-19 pandemic emphasized the need for process automation, using agile software development practices. However, when agile methods are used in scaled contexts, many software development efforts fail, mainly due to lacking requirements ...

Modeling is an essential and challenging activity in any engineering environment. It implies some hard-to-train skills such as abstraction and communication. Teachers, project leaders, and tool vendors have a hard time teaching or training their ...
