A mathematical model for an integrated airline fleet assignment and crew scheduling problem solved by vibration damping optimization

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

Integrated Airline Fleet and Crew Robust Planning

The airline fleet assignment problem involves assigning aircrafts to flights to maximize profit. Different fleet assignment solutions cause dramatically different performance in subsequent crew planning and operational processes. We have developed an integrated fleet and crew robust planning method to provide fleet assignment solutions that are both friendly to crew planning and robust to real ...

Heuristics to solve the integrated airline crew assignment problem

Article Info Abstract Keywords: air transportation airline crew assignment combinatorial optimization heuristics A typical problem related to airline crew management consists of optimally assigning the required crew members to planned flights for a given period of time, while complying with a variety of labor regulations, safety rules and policies of the airline. This problem, called crew assig...

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...

Two Mathematical Models for Railway Crew Scheduling Problem

Railway crew scheduling problem is a substantial part of the railway transportation planning, which aims to find the optimal combination of the trip sequences (pairings), and assign them to the crew complements. In this problem, each trip must be covered by at least one pairing. The multiple-covered trips lead to impose useless transfers called “transitions”. In this study, a new ma...
