InterAction of Bath has specialist knowledge of safety case development, gained through carrying out many projects in the defence sector.
We are skilled in the following techniques:
- Human error identification through human HAZOPS, SHERPA and CREAM.
- Human error quantification through HEART and THERP and from error rate databases. We also developed the Quasi-probabilistic Human Reliability Assessment technique for the UK MoD.
- Quantification of failure probabilities through close working relationships with designers during safety case development
- Error and failure modelling with fault tree and event tree analyses
- Safety case formats as defined in UK military standards (Def Stan 00-56 and JSP454)
Whatever the size of the system, the presence of human operators introduces the potential for human error. Good safety case management at the concept, design and production stages, as well as in operation, can reduce this potential to acceptable limits.
Our in-house software programme
InterRISK gives us the capability to manage safety cases comprehensively, to customer-specified formats and to provide accompanying electronic hazard logs with our reports. If required, we can also use the MoD's
Cassandra tool.
