More than a decade ago, the research topic models@ run. time was coined. Since then, the
research area has received increasing attention. Given the prolific results during these …

Software product line engineering has proven to empower organizations to develop a
diversity of similar software-intensive systems (applications) at lower cost, in shorter time …

This paper focuses on the challenges of modeling cyber–physical systems (CPSs) that arise
from the intrinsic heterogeneity, concurrency, and sensitivity to timing of such systems. It …

Over the last two decades, software product lines have been used successfully in industry
for building families of systems of related products, maximizing reuse, and exploiting their …

A self-adaptive system can automatically maintain its quality requirements in the presence of
dynamic environment changes. Develo** a self-adaptive system may be difficult due to …

Abstract Design of self-adaptive software-intensive cyber–physical systems (siCPS)
operating in dynamic environments is a significant challenge when a sufficient level of …

Context: Dynamic software product lines (DSPLs) have considerably increased their
adoption for variability management for self-adaptive systems. The most widely used models …

The two articles in this special section address the topic of systems and software vaiability.
Variability management involves two key challenges. First, industrial reality shows that for …

The engineering of high-quality software requirements generally relies on properties and
assumptions about the environment in which the software-to-be has to operate. Such …

Conventional approaches to self-adaptive software architectures require human experts to
specify models, policies and processes by which software can adapt to its environment. We …
