Refinement Propagation. Towards Automated Construction of Visual Specifications

Alain Wegmann, Irina Rychkova

Creation and transformation of visual specifications is driven by modeler’s design decisions. After a design decision has been made, the modeler needs to adjust the specification to maintain its correctness. The number of adjustments might make the design ...

Defining business process flexibility with the help of invariants

Alain Wegmann, Gil Regev

Enterprise survival is about maintaining an identity that is separate from other enterprises. We define flexibility as the ability to change without losing identity. The identity of an enterprise can be analyzed as a set of norms and beliefs about these no ...

Formalization of the RM-ODP foundations based on the Triune Continuum Paradigm

Andrey Naumenko, Alain Wegmann

The subject of research in this paper is RM-ODP, an ISO/ITU-T international standard. We investigate an important challenge that the standard faces, specifically the absence of a satisfactory formalization of its proposed conceptual framework. We report on ...
