Amion alternative built on mathematical optimization

Amion is a call schedule viewer and publishing tool — it displays schedules that your team has already built manually. Thrawn is a fundamentally different product: a done-for-you managed service that uses mathematical optimization to generate finished, conflict-free, ACGME-compliant schedules from your program's constraints. You submit your rules and preferences; Thrawn delivers a complete schedule for review.

Yes. Thrawn's Scheduling Programming Language enforces ACGME duty hour rules at the point of schedule generation, not after. Unlike tools that flag violations post-build, Thrawn prevents violations from appearing in the first place. Every schedule your team receives already satisfies the 80-hour weekly limit, required rest periods, and all applicable duty hour requirements.

Thrawn covers Block, Call, Clinic, and Attending schedules, optimized simultaneously as one integrated system. If your program currently uses Amion primarily for call schedule display, Thrawn replaces both the schedule-building work and the publishing function with a fully managed, optimized output your team reviews and approves.

Thrawn's scheduling specialists handle onboarding and configuration. Your program shares its constraints — rotation requirements, resident preferences, ACGME rules, vacation requests, and educational goals — and Thrawn configures the optimization engine for your specific program. There is no software for your team to learn or configure. The transition is managed end-to-end by Thrawn's team.

Thrawn serves 19 departments across 14 hospitals at multiple top-20 academic health systems on the East Coast, West Coast, and Southwest. The service is purpose-built for residency and fellowship programs, including both large academic departments and specialized fellowship programs with complex scheduling constraints.
