Optimal here and now decisions of multi stage robust optimisation: Optimale hier en nu beslissingen in multi stadia robuuste optimalisatie

Robust optimisation is shown to be extremely important in a wide range of applications including real life. Many research projects are dedicated to this relatively young and active research field and show the significant value of robust optimisation. Since many researchers have developed complex methods dedicated to robust optimisation, the aim...

Route Optimisation For Mobility-On-Demand Systems With Ride-Sharing

Privately owned cars are an unsustainable mode of transportation, especially in cities. New Mobility on Demand (MoD) services should offer a convenient and sustainable alternative to privately owned cars. Notable in this field is the recent uprise of ride-sharing services such as offered by companies like Uber and Grab. Such services, especially...

Searching for two optimal trajectories: A study on different approaches to global optimization of gravity-assist trajectories that have a backup departure opportunity

In interplanetary space missions, it is convenient to have a second departure opportunity in case the first is missed. Two distinct approaches to minimizing the maximum of the two Delta-V budgets of such a trajectory pair, are developed. The first (‘a priori’) approach optimizes the variables of both trajectories at once. The second (‘a...

Optimization of the Al-Shaheen Field Performance using Smart Well Technology

This MSc thesis reports the results on optimizing the Al-Shaheen field performance using smart well technology. The field is currently being developed by Maersk Oil and Gas (MOG) offshore Qatar, using large-scale water injection on very long horizontal wells. The studied reservoir consists of a laterally uniform, tight matrix. However, undesired...
