To optimize aircraft tail assignment while maximizing flight coverage and honoring various operational constraints.

A middle-east airline encountered significant challenges in managing tail assignments through manual processes. These manual practices led to increased complexity and operational risks as the fleet continued to grow, resulting in inefficiencies and potential scheduling conflicts. To overcome these obstacles, we developed an automated tail assignment optimization system designed to streamline operations and enhance decision-making capabilities. By leveraging advanced optimization techniques, we aimed to improve operational efficiency, reduce risks, and support seamless expansion for the airline.

  • Accelerated and more informed decision-making.

The implementation process began with a thorough analysis of the airline's existing manual assignment process and its limitations. We then formulated a Mixed Integer Programming (MIP) model that captured all relevant constraints and objectives. This mathematical model was designed to maximize flight coverage while balancing aircraft utilization across the fleet. The model incorporated various constraints ranging from operational requirements to scheduling restrictions and user preferences.

The IBM ILOG CPLEX optimizer was chosen to solve this complex model due to its ability to handle large-scale optimization problems efficiently. The team worked on data integration, ensuring that all necessary inputs - such as flight schedules, aircraft details, airport information, and maintenance schedules - were properly formatted and fed into the model.

A user-friendly interface was developed to allow planners to easily input parameters, run the optimization, and visualize the results. This interface also enabled "what-if" analysis, allowing users to adjust various parameters and quickly see the impact on the overall schedule.
