چکیده

The Event Refinement Structures (ERS) approach provides a graphical extension of the Event-B formal method to represent event decomposition and control-flow explicitly. In this paper we present an improved version of the ERS plug-in, which provides a graphical environment for the ERS approach within the Event-B tool, Rodin. The improved ERS plug-in is based on the available frameworks that are developed to support Event-B with an EMF framework, language extensions and generic diagram extensions.

Language and Tool Support for Class and State Machine Refinement in UML-B

UML-B is a ’UML-like’ graphical front end for Event-B that provides support for object-oriented modelling concepts. In particular, UML-B supports class diagrams and state machines, concepts that are not explicitly supported in plain Event-B. In Event-B, refinement is used to relate system models at different abstraction levels. The same abstraction-refinement concepts can also be applied in UML...

Building Traceable Event-B Models from Requirements

Constructing traceable Event-B models from requirements is crucial in the system development process. It enables the validation of the model against the requirements and allows to identify different refinement levels, which is a key to successful formal modelling with a refinement-based method. Our objective is to present an approach based on the use of semiformal structures to bridge the gap b...

Class and State Machine Refinement in UML-B

UML-B is a ’UML-like’ graphical front end for Event-B. It adds support for object oriented modeling concepts while visually retaining the Event-B modeling concepts. In the continuity of the work on UML-B, we strengthen its refinement concepts. Development in Event-B is done through refinements of an abstract model. Since Event-B is reflected in UML-B, the abstraction-refinement concepts must al...

Timing diagrams add Requirements Engineering capability to Event-B Formal Development

Event-B is a language for the formal development of reactive systems. At present the RODIN toolkit [15] for Event-B is used for modeling requirements, specifying refinements and doing verification. In order to extend graphical requirements modeling capability into the real-time domain, where timing constraints are essential, we propose a Timing diagram (TD) [13] notation for Event-B. The UML 2....

Evaluation of Graphical Control Flow Management Approaches for Event-B Modelling

Integrating graphical representations with formal methods can help bridge the gap between requirements and formal modelling. In this paper, we compare and evaluate two graphical approaches aiming at describing control flows and refinement in Event-B, and we use a fire dispatch system case study to perform this evaluation. The fire dispatch system case study provides a good example of a complex ...
