Role-based modeling has been investigated for over 35 years as a promising paradigm to
model complex, dynamic systems. Although current software systems are characterized by …

Just like current software systems, conceptual models are characterised by increasing
complexity and rate of change. Yet, these models only become useful if they can be …

Role-based modeling has been proposed in 1977 by Charles W. Bachman [Bachman et al.,
1977], as a means to model complex and dynamic domains, because roles are able to …

Since the year 1977, role modeling has been continuously investigated as promising
paradigm to model complex, dynamic systems. However, this research had almost no …

Just like current software systems, models are characterised by increasing complexity and
rate of change. Yet, these models only become useful if they can be continuously evaluated …

Self-adaptive Systems (SASs) are one way to address the ever-growing complexity of
software systems by allowing the system to react on changes in its operating environment. In …

Traditional modeling approaches and information systems assume static entities that
represent all information and attributes at once. However, due to the evolution of information …

In the increasingly dynamic realities of today's software systems, it is no longer feasible to
always expect human developers to react to changing environments and changing …

Adaptability is an intrinsic property of software systems that require adaptation to cope with
dynamically changing environments. Achieving adaptability is challenging. Variability is a …
