Robust and Recoverable Maintenance Routing Schedules

Michel Bierlaire, Matteo Salani, Niklaus Eggenberg

We present a methodology to compute more efficient airline schedules that are less sensitive to delay and can be recovered at lower cost in case of severe disruptions. We modify an original schedule by flight re-timing with the intent of improving some str ...

Constraint-specific recovery networks for solving airline recovery problems

Michel Bierlaire, Matteo Salani, Niklaus Eggenberg

In this paper, we consider the recovery of an airline schedule after an unforeseen event called disruption, making the planned schedule infeasible. We present a modeling framework that allows the consideration of operational constraints within a Column Gen ...

How robust are robust schedules in reality?

Michel Bierlaire, Matteo Salani, Niklaus Eggenberg

Due to economic pressure industries, when planning, tend to focus on optimizing the expected profit or the yield. The consequence of highly optimized solutions is an increased sensitivity to uncertainty. This generates additional "operational" costs, incur ...

The effect of access charges on social welfare in the railway industry

Matthias Finger, Marc Laperrouza

This paper presents a game-theoretic model of a liberalized railway industry in which train operation and ownership of infrastructure is fully vertically separated. The objective of this paper is to analyze how the regulatory agency will socially optimal s ...

Congestion in a competitive world: a study of the impact of competition on airline operations

Niklaus Eggenberg

Air transport is a fast developing area. Airlines compete for a limited resource, namely airport capacity. The consequence is an increase in airport congestion, which generates huge delays that are enhanced due to delay propagation through the whole networ ...

Explore the past to improve the Future: How can airlines benefit from historical data?

Niklaus Eggenberg

Airlines schedules are built such as to maximize expected profit. Such schedules turn out to be more sensitive to delay propagation and have lower on-time performance. Robust schedules are thus used instead. In this paper, we compare two different approach ...

A Study on the Impact of Competition on Airport Congestion

Niklaus Eggenberg

Air transportation in the US is increasingly faced with the problem of airport congestion: airlines tend to over-schedule to attract market share and revenue. Unfortunately, the airlines share a limited resource - airport capacity. The underlying question ...

Uncertainty Feature Optimization for the Airline Scheduling Problem

Matteo Salani, Niklaus Eggenberg

In this paper, we present an application to the Airline Scheduling Problem (ASP) of the Uncertainty Feature Optimization (UFO) framework which combines both a proactive scheduling algorithm and a reactive recovery algorithm used for re-optimization when di ...
