Fatigue safety examination of a riveted railway bridge using data from long term monitoring

Long term monitoring of structural elements of a 115 years old riveted railway bridge structure of high value as cultural heritage has been conducted. Monitored values were exploited by Rainflow analysis and served as the basis for the fatigue safety verif ...

Fatigue Life Assessment of Existing Motorway Bridge

Alain Nussbaumer, André-Gilles Dumont, Luca D'Angelo, Marc-Antoine Fénart

The aim of this paper is to provide a fatigue-life assessment of an existing composite steel-concrete bridge within Switzerland. The Venoge bridge is a 219 meters length, four spans, four girder composite bridge, situ-ated on the Geneva-Lausanne Swiss moto ...

Modeling work zone crash frequency by quantifying measurement errors in work zone length

Mehmet Yildirimoglu

Work zones are temporary traffic control zones that can potentially cause safety problems. Maintaining safety, while implementing necessary changes on roadways, is an important challenge traffic engineers and researchers have to confront. In this study, th ...

Robust Airline Schedules

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 ...

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 ...

Airline Disruptions: Aircraft Recovery with Maintenance Constraints

Michel Bierlaire, Matteo Salani, Niklaus Eggenberg

Airline schedules are rarely performed as planned because of irregularities such as delays, unpredicted maintenances or bad weather conditions. Recover from a disrupted schedule as quickly as possible is a hard and high priority problem for practitioners: ...

Airline Disruptions: Aircraft Recovery with Maintenance Constraints

Michel Bierlaire, Matteo Salani, Niklaus Eggenberg

In this paper we consider the recovery of an airline schedule after an unforeseen event, commonly called disruption, that makes the planned schedule unfeasible. In particular we consider the aircraft recovery problem for an heterogeneous fleet of aircrafts ...
