Many variability modeling approaches consider only formalized dependencies, i.e. in- or exclude relations between variants. However, in real industrial product families, dependencies are often much more complicated. In this paper, we discuss the product derivation problems associated with dependencies, and show how our variability modeling framework COVAMOF addresses these issues. Throughout the paper,...
Software product lines (PLs) are large, complex systems, demanding high maintainability and enhanced flexibility. Nonetheless, in the state of the art PL methods, features are scattered and tangled throughout the system components, leading to poor maintainability. Additionally, the majority of PL methods support manual product composition, while the implementation of feature-level variability in PL...
Approach presented in the paper is based on so-called STEPs (scheduling time-points). Using input information about test schedule constraints, information about test resource sharing conflicts stored in a TACG (test application conflict graph) and information about power dissipation, test time and TAM (test access mechanism) width of particular tests going to be scheduled, proposed test scheduling...
Situation assessment and decision making (SA & DM) in mission critical scenarios is a complex cognitive task involving assessment of numerous variables which are often interdependent. Tasks are performed by individuals, teams and organizations and information is provided by different sources. Team members often perform a specific role, but must share information and a common understanding of the...
Multihop message routing is a well studied and widely documented area of research in wireless sensor networks (WSN), where the dynamic and lossy nature of the wireless medium and severe resource constraints pose major challenges. The vast majority of related research focuses on reliable and power-efficient transfer of small amounts of data, such as low frequency sensor readings or event detections...
With significant advances in software development technologies in recent years, it is now possible to have complex software applications, which include a large number of heterogeneous software components distributed over a large network of computers with different computational capabilities. To run such applications, their components must be instantiated on proper hardware resources in their target...
