Automate and standardize Model-Based Safety Assessment (MBSA) within a CI/CD pipeline to enhance safety verification for complex systems.

Abstract

Model-Based Safety Assessment (MBSA) offers a powerful approach for ensuring the safety of complex, software-intensive systems across industries like aerospace, rail, and automotive. However, effectively integrating MBSA with iterative development processes and aligning it with functional safety standards remains challenging. This project proposes a solution centered on automating verification tasks within a CI/CD pipeline. This includes tailored workflows, report generation, and robust traceability mechanisms.

Problem Statement

The lack of well-defined, standards-compliant processes for integrating formal model verification into MBSA pipelines hinders efficiency and reliability. Manual verification and report generation are time-consuming and prone to inconsistencies. Additionally, ensuring traceability between evolving models and their verification results is essential but often complex.

Research Questions

  1. How can a CI/CD workflow be designed to seamlessly trigger model verification tasks based on identified changes and relevant safety standards?
  2. What mechanisms can automate the generation of standardized verification reports while ensuring compliance with functional safety norms?
  3. How can a robust traceability solution be developed to guarantee a clear connection between model versions and their corresponding verification outcomes?

Methodology

  1. CI/CD Workflow and Plugin: Design a workflow and develop a plugin for platforms like Jenkins or GitHub, automating verification task execution based on customizable triggers and safety considerations.
  2. Report Generation: Define report templates aligned with relevant functional safety standards. Implement automated report generation with extracted verification results.
  3. Traceability Mechanism: Design a method to establish and maintain clear links between model iterations and their verification reports.
  4. Storage: Develop a data storage mechanism for models, verification tasks, and reports, ensuring accessibility and long-term traceability.

Student Opportunities

  • MBSA and Functional Safety: Gain in-depth knowledge of Model-Based Safety Assessment principles and functional safety standards in real-world applications.
  • State-of-the-Art Tools: Work with cutting-edge modeling tools and formal verification frameworks.
  • Agile Development: Experience collaborative software development within a team using Scrum-like methodologies.

Significance

This project delivers a significant contribution by streamlining MBSA processes. It promotes consistency, traceability, and compliance with safety standards, ultimately enhancing the reliability and efficiency of developing safety-critical systems.
