In the last years we are observing a growing interest in verification of business process
models that, despite their lack of formal characterization, are widely adopted in industry and …

We present the formal underpinnings of a modelling and analysis framework for the
specification and verification of variability in product families. We address variability at the …

The variability model checker VMC accepts a product family specified as a Modal Transition
System (MTS) with additional variability constraints. Consequently, it offers behavioral …

In the ever expanding universe of formal methods, several tools exist that can be exploited to
validate early system designs, and that are applicable to problems of the railway domain. In …

We present VMC, a tool for the modeling and analysis of variability in product lines. It
accepts a product family specified as a modal transition system, possibly with additional …

During the last decades, a large amount of multi-valued transition systems, whose
transitions or states are labeled with specific weights, have been proposed to analyze …

We demonstrate that modal transition systems with variability constraints are equally
expressive as featured transition systems, by defining a transformation of the latter into the …

Service-oriented computing, an emerging paradigm for distributed computing based on the
use of services, is calling for the development of tools and techniques to build safe and …

Formal methods and verification technique are often used to develop mission-critical
systems. Cloud computing offers new computation models for applications and the new …

We describe the development of the KandISTI family of model checkers from its origins
nearly two decades ago until its very recent latest addition. Most progress was made …
