Generate Hazard log item for Hazard
KERNEL-19 Failure of train trip supervision in OS, LS and FS
(Related to model of Subset 26 §5.9 Procedure On-Sight)
Work scope:
System structure breackdown:
- Analyse Subset 26 input (and additional)
- Identify main components at system level and limits
System functional breackdown:
- Identify main functions at system level
- Identify lower level kernel functions (based on the benchmark model)
- Synchronising understanding with the author of the model
- pre-release draft results to https://github.com/openETCS/validation/tree/master/SafetyCase
- Compare work of Subset 88 & 91 to functional breakdown - Complete discription of the hazard in relation to it source (System FMEA in Subset 91 Annex A)
- Top down analysis to identify corresponding exidents
