Pre-Releasing Strategies for Same-Day Home Delivery: Comparing Heuristics for Partially Dynamic Vehicle Routing with Stochastic Customers

This thesis investigates the optimization of Same-Day Delivery (SDD) in the context of a Dynamic and Stochastic Vehicle Routing Problem with Time-Windows (DSVRPTW). A central focus is the concept of pre-releasing; the process of assigning an order to a specific route and preparing it for delivery, effectively fixing theorder to the route. This...

Isogeometric analysis of fluid cellular membranes: Application of discrete exterior calculus and isogeometric analysis to Stokes flow on time-evolving surfaces

An isogeometric finite element method for incompressible fluid film equations is presented. The method can be applied to numerically model the behaviour of thin cellular membranes, such as lipid bilayers. The membranes are represented by infinitely thin closed surfaces. Both the surface parametrization and analysis are based on state-of-the-art...

Maximum likelihood estimation of parameters in the exponential random graph model

In this report the method of Markov chain Monte Carlo maximum<br/>likelihood estimation was used to estimate parameters in the Ising model<br/>and the exponential random graph model. The method and the models<br/>where described mathematically and problems that occurred during the<br/>estimation process where discussed. A package that executes...
