BPMN is a leading visual notation for modeling business processes. Although there is many tools that allows for modeling using BPMN, they mostly do not support formal verification of models. The Alvis language was developed for modeling and verification of embedded systems. However, it is suitable for the modeling of any information systems with parallel subsystems. The goal of this paper is to...

Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and objectoriented modeling principles, enabling good reuse ...

This paper describes a case study conducted in collaboration with Nortel to demonstrate the feasibility of applying formal modeling techniques to telecommunication systems. A formal description language, SDL, was chosen by our qualitative CASE tool evaluation to model a multimedia-messaging system described by an 80-page natural language speci cation. Our model was used to identify errors in th...

We present an mda framework, developed in the functional programming language sml, that tries to bridge the gap between formal software development and the needs of industrial software development, e.g., code generation. Overall, our toolchain provides support for software modeling using uml/ocl and guides the user from type-checking and model transformations to code generation and formal analy...

The primary objective of software specification is to promote understanding of the system properties between stakeholders. Specification comprehensibility is essential particularly during software validation and maintenance as it permits the understanding of the system properties more easily and quickly prior to the required tasks. Formal notation such as B increases a specification’s precision...

UML is a standard modelling language that is able to specify a wide range of object-oriented concepts. Among them, we have collaborations, that serve to realise use cases, a powerful abstraction concept. The behaviour part of a collaboration is rendered using collaboration diagrams. However, the lack of formalisation compromises the precision of the specification. By using formal description te...

The reasons for software project failures are mostly project management related issues. Without analyzing these issues in failed projects or capturing the best practices in successful ones, repeating mistakes is inevitable. We developed a project management modeling language (PROMOL) that helps us to plan, understand, analyze and document management of software projects. PROMOL is a formal and ...

This paper presents a framework for representing formal semantics of a subset of the Unified Modeling Language (UML) notation in a higher-order logic, more specifically semantics of UML sequence diagrams is encoded into the Prototype Verification System (PVS). The primary objective of our work is to make UML models amenable to rigorous analysis by providing their precise semantics. This approac...

The Agent Modeling Language (AML) is a semi-formal visual modeling language for specifying, modeling and documenting systems that incorporate features drawn from multi-agent systems theory. It is specified as an extension to UML 2.0 in accordance with major OMG modeling frameworks (MDA, MOF, UML, and OCL). The ultimate objective of AML is to provide software engineers with a ready-to-use, compl...
