Stand capacity assessment is an essential factor in airport planning and design due to the large investments associated with airport development. Fulfilling anticipated demand while still considering future growth is key in airport master planning. In this paper, a mixed-integer linear programming optimisation model is proposed, which determines...

The runway usage of complex airports with multiple runways is currently prescribed by a preference list. The preference list mostly focuses on minimizing noise and it provides a more manageable flow for ATC. However, it does not consider the fuel burn or current demand of flights. This study presents a MILP scheduling model which optimizes for...

Planning the on-site transportation of large manufacturing sites is a complex process. Currently these plans are made based on the on-site logistics constraints rather than on KPIs. Research has been focused on either analysis of system parameters or generally on KPIs, but lacks the combination of both on real-life cases. This gap is closed by...

In this report, supply chains of factory outlet stores are analyzed. Here, the concept of factory outlet stores have been investigated in literature to be able to understand which goal these stores serves. Based on a pull based supply chain perspective, replenishment has been investigated. Here, demand forecast, inventory, order ful_llment and...

In this study, various scenarios were developed that correspond to estimations of future biomass availability and biofuel demand from the maritime industry. These marine biofuel demand scenarios were based on the Greenhouse Gas (GHG) reduction targets of the Renewable Energy Directive II (RED II) and the International Maritime Organization (IMO)...

Due to new legislation, a lot of research is done in the development of a Collision Avoidance Systems (CAS) for surface mines. Almost all CASs studied in literature are decentralized and developed for passenger vehicles or aviation applications. That makes them unsuitable for the mining environment. A centralized system can ensure optimal...

<br/>This thesis is done in cooperation with Sime Darby Oils Zwijndrecht (SDOZ). SDOZ is a refinery of vegetable based oils. The goal of this thesis is to optimize the scheduling of the Refined Oil Storage (ROS) of the refinery. This is done because within the company it is suspected that the current way of assigning the tanks, that is...

The rapid growth of rooftop solar, and on the rise technologies such as electric vehicles and heat pumps, is leading to congestion problems in low voltage distribution networks. If not dealt with, the congestion will prevent the installation of further units limiting the pace of the energy transition. Energy Storage Systems (ESS) are often seen...

Passengers often complain about dirty trains indicating the relevance of interior cleaning of rolling stock (RS). Servicing tasks (i.e. interior and exterior cleaning and smaller technical checks) are executed on a daily basis at service locations (SLs). Currently, due to train operations during daytime, the current focus lies on night servicing...

The steady growth of air traffic volumes and the subsequent increase of congestion at major airports require airports to increase their operational efficiency. Inefficient or the absence of gate reassignment models increase the possibility and occurrence of gate blockage and at the same time reduce the comfort of passengers as they often receive...

Traditional electric power systems with large centralized base load power plants have a limited ability to react rapidly to the high supply variability associated with the increasing deployment of variable and intermittent renewable energy sources (RESs). Furthermore, with current power distribution networks primarily designed for unidirectional...

In this thesis, we propose two mixed integer linear program formulations for an optimization problem that incorporates annualized hours: an exact one and an approximation. The objective of our model consists of three weighted parts: a part which minimizes the difference between working hours and contract hours for each employee per week, a part...

Recent advances on the design of autonomous mobile agents have motivated the use of the latter in persistent surveillance tasks with applications in agriculture, information gathering and search and rescue missions. In these tasks the goal is to design agents’ paths so as every point in the area of interest is covered more than once. In...

In times when there is more and more focus on environmental impact, all aspects must be taken into account. Expanded polystyrene (EPS) is easy and cheap to produce and has lots of applications because of its properties. These properties however, also make it a hard material to recycle. This paper focuses on a rich mathematical model for the...

Manufacturing processes often run on a schedule, because each production step takes a certain amount of time, after which a component is transported to the next machine. Mobile robots can be used to automate transportation of components between production steps. To do so, a task scheduler assigns transportation tasks to robots and a path planner...

To overcome the disadvantages of radar vectors and to improve efficiency and safety of terminal airspace operations, EUROCONTROL has proposed the so-called Point Merge System (PMS) technique for merging inbound traffic flows. As the PMS provides better predictability, it can potentially offer significant fuel and environmental benefits as well...

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...

In this thesis, we analyse the optimisation of an annualised hours problem. Annualised hours problems are a widely studied subjects, in which the working hours for a given number of employees per week are minimised. We approach this problem with a mixed integer linear program, where the objective function of this problem is divided into two...

The taxi procedure at an airport refers to the surface movement of the aircraft between the parking position and the runway or vice versa. Nowadays, aircraft tend to taxi with the main engines, even if they are not optimized for it. Using an alternative suitable taxiing system that fulfills the requirements of the taxi procedure could be a...

We study the integration of real-time traffic management and train control by using mixed-integer nonlinear programming (MINLP) and mixed-integer linear programming (MILP) approaches. Three innovative integrated optimization approaches for real-time traffic management that inherently include train control are developed to deliver both a train...
