Crew Optimization

ROZETTACREW

Compliant Rosters. Built Fast.

Fast optimization. Full regulatory compliance. Fair rosters for every crew member. RozettaCrew solves pairings and rostering together so nothing falls through the cracks.

The Two-Stage Optimization Pipeline

When pairings are locked before rostering starts, your crew assignments are already compromised. RozettaCrew optimizes both together, generating pairings that are built for the crew who will actually fly them.

01

SCHEDULE INPUT

Upload or sync your flight schedule. The system ingests rotation data, base assignments, aircraft types, and collective agreement parameters.

02

PAIRING OPTIMIZER

Column generation builds a full candidate pool of feasible pairings, shaped by real crew constraints: skeleton rosters, base coverage, remaining flight hours.

03

POOL PASSED TO ROSTERING

The rostering engine receives the full pool of candidate pairings. Each one carries a rosterability score, so the optimizer knows how assignable every pairing is before making a single decision.

04

ROSTERING OPTIMIZER

A combined set-partitioning solver simultaneously selects which pairings to use AND which crew member gets each one. Co-optimized, not sequentially assigned.

05

PUBLISHED ROSTER

Legal, fair, and feedback-ready. Bidirectional loop auto-pre-fills the pairing optimizer if rostering surfaces assignment failures.

8× Faster Than the Tools You Use Today.

Conventional crew optimization tools treat pairing and rostering as sequential batch jobs. This often takes 6 to 14 hours to produce a single solution for a mid-size fleet. RozettaCrew’s optimization engine generates optimized rosters under 90 minutes for 600+ crew across a 30-day bid period.

Multi-scenario runs complete in the same working session. Compare Cost-Focused, Rosterability-First, Robustness-First, and Balanced side by side
Late schedule changes re-solved in under 2 hours with no overnight batch cycle
IROPS recovery options surfaced in under 60 seconds from event onset
Live iteration progress including column count, bound gap, and estimated time remaining visible in real time throughout

Multiple Scenarios. One Informed Decision.

Run Cost-Focused, Rosterability-First, Robustness-First, and Balanced scenarios simultaneously. All complete in a single working session, not an overnight batch. Compare them side by side across cost, rosterability, deadheads, hotel nights, and feasibility. Then pass the winning pool directly to rostering with a single click.

No more black box outputs. No more waiting until morning to discover an assignment failure. RozettaCrew shows you the trade-offs in real time, before you commit.

IROPS Recovery. Applied in Seconds.

When an aircraft goes AOG, a crew member exceeds FDP, or a delay cascades across rotations, the Disruption Manager surfaces instantly with AI-ranked recovery options. Each option is scored by cost, legality probability, crew impact, and passenger delay. All of this is presented in a high-urgency, purpose-built interface.

Legality Is Non-Negotiable.

Every duty assignment is validated in real time against the complete EASA FTL, FAA Part 117, or your airline’s custom CBA ruleset. This applies whether the assignment is generated by the optimizer or placed manually. The algorithm accounts for violations as it runs, not after. When one is detected, it is flagged on the Gantt bar with the regulation reference, current versus maximum value, and a suggested alternative.

Before any assignment is confirmed, a pre-commit dialog shows the legality outcome, cost delta, and fatigue impact. Nothing destructive can be executed without a full impact acknowledgement.

FLIGHT DUTY PERIOD

Maximum FDP tracked against sector count, acclimatization state, and augmented crew rules. Real-time counter on every Gantt bar.

MINIMUM REST REQUIREMENTS

Rest periods checked before any duty assignment can be placed. Shortened rest, split rest, and hotel rest rules all supported.

28 DAY & ANNUAL FLIGHT HOUR LIMITS

Rolling 28-day and 365-day block hour accumulators with configurable warning thresholds and burn-rate analytics.

CUSTOM CBA RULESETS

Import your airline’s collective bargaining agreement as a structured ruleset. Combine your custom rules with any EASA/FAA parameter at the CBA layer.

Fatigue Management

Fatigue Management module computes individualized biomathematical alertness curves for every crew member based on their actual duty history and circadian phase, surfacing a fleet-wide fatigue heatmap that shows who is approaching critical thresholds before the roster is ever published. Fatigue scores feed directly into the crew optimization to generate rosters that are not just legally compliant, but physiologically sound from the start.

Preferential Bidding

Preferential Bidding module collects ranked preferences from every crew member and runs a seniority-aware award engine that maximizes fleet-wide satisfaction as an optimization objective. Every crew member receives a transparent denial reason report showing exactly which preferences were awarded, which weren’t, and why, turning what is typically a source of grievances into a documented, auditable process.

Training & Compliance

Training & Compliance module keeps every simulator session, line check, CRM course, and medical renewal on a single shared calendar, visible alongside the live roster so scheduling conflicts are caught before they happen. Training windows, qualification expiry dates, and recency requirements are fed directly into the crew optimization, so the generated roster already accounts for who needs to be grounded for a sim session, who is approaching a currency deadline, and who cannot legally operate until a certification is renewed.
