Hitit Empowers Airlines to Optimize Crew Leave Planning with Gurobi

Gurobi Optimization, LLC, the leader in decision intelligence technology, is proud to be the solver of choice for Hitit, a leading global provider of airline and travel IT solutions.

Hitit’s Crane Crew Leave Optimizer—one of the key sub-modules of Hitit’s Crane Crew solution—enables airlines to quickly generate optimal leave schedules for thousands of crew members. Powered by Gurobi’s mathematical optimization solver, the tool significantly reduces planning time while improving both operational efficiency and crew satisfaction.

Among the many constraints that airlines must consider are operational requirements, business rules, crew seniority, and personal preferences. As such, manual planning efforts can often lead to inefficiencies, crew dissatisfaction, and compliance risks.

After switching to Crane Crew, Hitit’s partner airlines have reported significant improvements. What once took weeks to accomplish can now be completed in as little as seconds, with leave bids submitted via a streamlined mobile application and optimal plans generated automatically.

“These advancements have been made possible through Hitit’s collaboration with Gurobi,” explained Nevra Onursal Karaağaç, CEO of Hitit. “By integrating Gurobi’s industry-leading solver into its planning system, we have been able to tackle the complexity of leave planning with a data-driven, scalable approach—transforming a manual, error-prone task into a fast and fair optimization process.”

"Crew members play an essential role in every airline’s success. Planning annual leave periods in a way that not only maximizes efficiency, but also crew satisfaction, is critical,” said Duke Perrucci, CEO of Gurobi Optimization. “By leveraging mathematical optimization, Hitit creates plans that deliver tangible value for both airlines and their employees.”
