This paper proposes a methodology to analyze graph transformation systems by means of
Alloy and its supporting tools. Alloy is a simple structural modeling language, based on first …

Angelic nondeterminism can play an important role in program development. It simplifies
specifications, for example in deriving programs with a refinement calculus; it is the formal …

We present Dash, an extension to the Alloy language to model dynamic behaviour using the
labelled control state hierarchy of Statecharts. From Statecharts, Dash borrows the concepts …

We describe DynAlloy Analyzer, a tool that extends Alloy Analyzer with support for dynamic
elements in Alloy models. The tool builds upon Alloy Analyzer in a way that makes it fully …

This paper explains how the Alloy model-finding method has been used to check the
specification of an electronic purse (also called smart card) system, called the Mondex case …

DynAlloy is an extension of Alloy to support the definition of actions and the specification of
assertions regarding execution traces. In this article we show how we can extend the Alloy …

Alloy is a formal specification language, which despite featuring a simple syntax and
relational semantics, is very expressive and supports efficient automated specification …

Alloy specifications are used to define lightweight models of systems. We present Alchemy,
which compiles Alloy specifications into implementations that execute against persistent …

DynAHoy is an extension of the Alloy specification language that allows one to specify and
analyze dynamic properties of models. The analysis is supported by the DynAlloy Analyzer …

Abstract The Unified Modeling Language (UML) is widely considered as the defacto
standard for the design of Object Oriented systems. UML class diagrams are used to depict …
