Event-B is a formal method for system design and verification that employs a structured, incremental approach to refine system models, facilitating the development of complex systems in a rigorous and systematic manner. This approach ensures system reliability using mathematical notations and the correct-by-construction principle, which guarantees that the system meets its specified requirements. The incremental refinement process allows for the gradual introduction of complexity, enabling developers to ensure the accuracy of every refinement stage. However, the complexity of Event-B and its primary tool, RODIN, can make model construction and relationship management challenging, particularly for non-experts and when dealing with complex or ambiguous system requirements. The abstract nature of Event-B notations and the need to manage multiple models and refinements can be overwhelming, leading to errors and inconsistencies in the modeling process. To address these challenges, this research proposes developing a graphical interface and system automated frameworks to simplify Event-B modeling. The EazyB tool combines graphical modeling with automatic code generation, enabling users to visually create and modify models while maintaining formal rigor. By offering user-friendly templates and interactive features, the tool aims to reduce the learning curve, enhance usability, and make Event-B more accessible to beginners. The EazyB essentially helps to generate the Event-B model templates automatically with their component relationships based on the graphical depiction of the system requirements and also generate corresponding Java Script codes from the Event-B models. The graphical interface will provide an intuitive representation of the system, allowing users to easily navigate and understand the complex relationships between components. Additionally, the automated code generation feature will eliminate the need for manual coding, reducing the risk of errors and inconsistencies. This, in turn, will promote the widespread adoption of Event-B in various fields, including safety-critical systems, and improve system reliability and efficiency.
