Strategic Airline Crew Sizing: A Two-Stage Stochastic Optimisation Approach

This paper introduces a new two-stage stochastic optimisation approach for the strategic airline crew planning problem with uncertain demand. The developed model provides the airline with a cockpit crew composition plan per crew position before the flight schedule and crew demand are known. This is done by estimating future crew demand and by...

Probabilistic Reliability Assessment for Non-Linear Finite Element Analysis of Reinforced Concrete Beams

Non-linear finite element analysis (NLFEA) is a powerful numerical solution method that can enhance accurate determination of the structural resistance for a more efficient design. However, the implementation of NLFEA for the design of reinforced concrete structures is lagging behind as related uncertain- ties have not been quantified adequately...

Stochastic Beach Width Prediction at a Recently Nourished Beach

This study examines a method for a stochastic beach width prediction with a process-based morphodynamic model. This is carried out by a case study at the Hondsbossche Dunes, after a beach nourishment in March 2018. Stochastic forcing conditions are generated for the location of the Hondsbossche Dunes. These stochastic forcing conditions consist...

Quantifying coastline change uncertainty using a multi-model aggregation approach

Evolution of coastline position under the influence of natural and anthropogenic processes is directly linked to the development of seaside societies. In the context of coastal zone management, process-based morphodynamic models are often used topredict coastline evolution and support the decision-making process...

Effect of stochastic material properties on the structural response of laminated composite materials: following the building block approach

This report, which from now and onwards will be called the main body of the thesis, covers the core of the<br/>problem that has to be solved. Generally, the aim of this thesis is to investigate a laminated composite’s<br/>structural response, made of FRP, when its material properties are assumed stochastic instead of<br/>deterministic. The...

Towards an efficient sensitivity analysis of wave forcing in coastal erosion studies: A case study of Negril Coast, Jamaica

This research investigates approaches to conduct an efficient sensitivity analysis of wave forcing in coastal erosion studies. For this three speed-accuracy trade-offs have been assessed: (i) between the use of a simple and a complex model, (ii) between the use of several methods for conducting a sensitivity analysis, and (iii) between the use...

The Variability of Traffic in Congestion Forecasting

Congestion on the Dutch motorway network is an actual problem, which originated over the past decades. Over the past few years, the extent of congestion is decreasing, though still very significant. Road authorities therefore show interest in traffic congestion forecasting. In this way they can inform road users or undertake other strategic...
