Optimization of bike-sharing repositioning operations: A reactive real-time approach
One of the critical issues in the operation of vehicle-sharing systems is the optimization of the fleet repositioning movements. Repositioning implies the artificial movement of vehicles from places where they accumulate to others in which they are ...

Airline fleet assignment with internal passenger flow reevaluations
The airline fleet assignment problem consists of assigning an aircraft type to each flight leg of a flight schedule in order to maximize the airline expected profit. Most existing fleet assignment models (FAMs) use an estimation of the revenues per flight leg that neglects the interdependency between the flight legs and poorly approximates the spill ...
