Box set optimization for e-commerce warehouses: Applied to bol.com

The problem considered in this thesis is the box set optimization problem. In<br/>this problem the goal is to find the optimal dimensions of a number of shipping<br/>boxes which have to provide an optimal fit on a set of items. The application<br/>considered is e-commerce, and hence the number of items is relatively large<br/>compared to other...

An optimization model for 3D loading space for the transport of large steel structures

In this report, a model is presented that automates and optimizes the loading processes for the transport of steel structures at the company of ASK Romein. This transport can be captured in two main loading processes: the loading division, which consists of allocating items to different trailers, and the loading sequence, which considers placing...

A bin packing approach to solve the aircraft maintenance task allocation problem

This paper addresses the scheduling of aircraft maintenance tasks that must be carried out in multiple maintenance checks to keep a fleet of aircraft airworthy. The allocation of maintenance tasks to maintenance opportunities, also known as the task allocation problem (TAP), is a complex combinatorial problem that needs to be solved daily by...

Full Color High Definition Fused Filament Fabrication

Although Full Color (FC) High Definition (HD) Additive Manufacturing (AM) machines are available on the market today, a FC HD Fused Filament Fabrication (FFF) printer has yet to enter the competitive FFF market. Leapfrog, a FFF printer manufacturer, holds a patent that allows the application of coating on 3D printed FFF filament after it has...

Moment methods in extremal geometry

In this thesis we develop techniques for solving problems in extremal geometry. We give an infinite dimensional generalization of moment techniques from polynomial optimization. We use this to construct semidefinite programming hierarchies for approximating optimal packing densities and ground state energies of particle systems. For this we...

SIMPLER AND FASTER: A 2.5D PACKING-BASED APPROACH FOR EARLY STAGE SHIP DESIGN

A Packing Approach for the Early Stage Design of Service Vessels

Naval architects often say that every ship is a compromise between many conflicting requirements. This widely-held belief immediately raises the question as to what kind of ship and, therefore, what kind of compromise, would suit the ship owner’s interest best. The approach presented in this thesis aims to improve the early stage design process...
