Methodology
How the hospital demo is grounded
Every number in the demo comes from either the synthetic PBJ-shaped fixture set, the benchmark harness, or the cached QPU trace written into the repository.
Evidence
Regulatory sources
- CMS Payroll-Based Journal public staffing distributions for the roster shape and hour mix.
- AACN ICU staffing guidance for critical-care coverage assumptions.
- AORN perioperative staffing guidance for scrub and circulating nurse requirements.
- The Joint Commission HR competency expectations for certification-driven coverage constraints.
Solvers
Solver settings
- Classical path: OR-Tools CP-SAT on the live backend.
- Hybrid path: repair-window QUBO with a cached QPU trace and an Aer-backed fallback.
- QAOA defaults: reps=1, maxiter=12, shots=256, seed=1234.
- Penalty policy: hard lambda = 10x the max objective coefficient; soft weights tuned in the repository fixture file.

Cached QPU trace
Production demo replays a recorded IBM Quantum run for recording-safe deployments. Live QAOA remains available for research environments.
