Models and Algorithms for an Integrated Fleet-Assignment, Aircraft-Routing and Crew-Pairing Problem

We study an optimization problem of a regional airline company. The problem integrates three stages of the planning process that are typically solved in sequence: fleet assignment, aircraft routing and crew pairing. Aircraft maintenance is also taken into account. We present two mathematical formulations for the integrated problem. One formulation could be considered the natural model where bot...

Integrated Airline Operations: Schedule Design, Fleet Assignment, Aircraft Routing, and Crew Scheduling

An integrated fleet assignment and itinerary choice model for a new flexible aircraft

In this paper we present methodologies for improving the demand-responsiveness of air transportation systems. The main ingredients are the flexibility in transportation capacity provided by an innovative aircraft and an integrated model where supply-demand interactions are explicitly formulated. The integrated model benefits from the simultaneous schedule planning and revenue management decisio...

Fleet assignment and routing with schedule synchronization constraints

This paper introduces a new type of constraints, related to schedule synchronization, in the problem formulation of aircraft ̄eet assignment and routing problems and it proposes an optimal solution approach. This approach is based on Dantzig±Wolfe decomposition/column generation. The resulting master problem consists of ̄ight covering constraints, as in usual applications, and of schedule synch...
