Temporal logic model checking involves checking the state-space of a model of a system to
determine whether errors can occur in the system. Often this involves checking …

We present an automatic technique for the detection of structural symmetry in a model
directly from its Promela specification. Our approach involves finding the static channel …

IVR (Interactive Voice Response) services are increasingly prevalent in automated
telephone enquiry systems. VoiceXML (Voice eXtensible Markup Language) has become …

Symmetry reduction techniques aim to combat the state-space explosion problem for model
checking by restricting search to representative states from equivalence classes with respect …

The application of model checking is limited due to the state-space explosion problem–as
the number of components represented by a model increase, the worst case size of the …

Features are a structuring mechanism for additional functionality, usually in response to
changing requirements. When several features are invoked at the same time, by the same …

Much of the literature on symmetry reductions for model checking assumes a simple model
of computation where the local state of each component in a concurrent system can be …

A general technique combining model checking and abstraction is presented that allows
property based analysis of systems consisting of an arbitrary number of featured …

We present a new verification technique for Promela which exploits state-space symmetries
induced by scalarset values used in a model. The technique involves efficiently computing a …

Abstract Distributed Feature Composition (DFC) is an architecture developed by Jackson
and Zave at AT&T to describe and implement telecommunication services. DFC supports …
