Simulations
Scenarios (scenario set r2)
| Scenario | Description | Runs |
|---|---|---|
| BASE | Night; hillside footpath exit X3 assumed lost to the fire front; guests asleep (response 60–900 s) | 3 independent builds |
| ALT-ALL | Sensitivity: all four exits available; response 60–900 s | 3 independent builds |
| ALT-EXIT | Layout alternative: new 2.0 m gate X5 (courtyard to car park); X3 lost; response 60–900 s | 3 independent builds |
| ALT-WARN | Operational alternative: staff wake-up warning (response 30–300 s); X3 lost | 3 independent builds |
| ALT-WARN-EXIT | Sensitivity: staff warning plus gate X5 (response 30–300 s); X3 lost | 3 independent builds |
- Solver
- IES Simulex (IESVE 2026, Simulex32.exe 2026.0.0.0), 2026-10-24
- Execution
- Hexanta Windows UI automation of Simulex's own menus and dialogs; no operator input; no Simulex API exists
- Independent samples
- Each run is a fresh build (new random response-time draws). Reopening a saved project reruns it identically (10 reruns checked), so reruns are reproducibility checks, not samples.
- Office engine test
- HX-OFFICE-01, 2 runs (BASE, east exit blocked); evidence simulex-HXO01-20261024-r2. The first generation simulex-HXO01-20261024 is SUPERSEDED.
- Attempts without a result
- Four aborted attempts were stopped by the driver's guards (exit rotation, view calibration) and are kept in the job record; none is used here.
Sanitised derivative of preserved evidence (simulex-HXM01-20261024, simulex-HXO01-20261024-r2, simulex-JOB-20261024). Plots and the report were drawn by Hexanta from values in the Simulex results files; screenshots are cropped and visually reviewed. Nothing was re-simulated. · Pack la-hotel-evacuation-r3 (built 2026-10-25); every file is checked against its SHA-256 before it is shown.
