  1. Software lifecycle support and management system for safety-related signalling systems Lei Chen Research institute of general technology Beijing National Railway Design and Research Institute of Signal and Communication Co. Ltd.

  2. INTRODUCTION Major challenges Task analysis approach The software lifecycle support and management system for safety-related signalling system • The architecture of SwSLMS • Key innovations • Trial use Conclusion

  3. MAJOR CHALLENGES Demanding project schedule and high RAMS requirement Coordination of different roles Information explosion and information islands Development assistance Time consuming testing Knowledge share and reuse

  4. TASK ANALYSIS APPROACH EN50128 CRSCD

  5. TASK ANALYSIS APPROACH

  6. The architecture of SwSLMS

  7. Key innovations Quality gate control • UUM • Access and role control

  8. Key innovations Information fusion

  9. Key innovations Development assistance • Collaboration development tool • Code completion tool • Instant code rules check-up tool • Covered 60% of the coding standards and coding style requirements • Cross compile tool and debugger

  10. Key innovations Automatic testing

  11. Key innovations Component based knowledge base • A new concept of COMPONENT • software requirements • interfaces, designs • codes, test cases • test scripts • test records • relevant documents

  12. Trial use Zone control certre(ZC) • Software test stage • Functional test cases: 694 • One round of testing • Original: 20 test cases per day per person, totally 35 man-day • SwSLMS: 8 machine hours

  13. CONCLUSION Fully compliant with the new EN50128. Tentative effort to solve the contradiction of limited time of a project and high RAMS performance requirements Based on human factor study and task analysis Positive comments on SwSLMS
