Subsea pipelines are critical for oil and gas production and transport, more than 100.000kmof subsea pipelines have been laid. These pipelines are laid by specially designed ships which can lay these pipelines at great depth and a high speed. However, designing the supply chain to deliver joints (pipe pieces) to these pipe lay vessels can be...

The past decade has seen a continuous increase of Earth observation missions, since they are regarded as an important tool to address global problems such as climate change or disaster mitigation. A commercial trend exists now towards higher resolution imagery, which drives the use of agile satellites. Nevertheless, a disadvantage of agile...

In recent years, airlines have increasingly developed the ability to monitor the condition of aircraft components by means of sensors. In turn, aircraft maintenance aims to use this sensor data to predict component failures. However, the challenge remains to make use of these prognostics to generate appropriate maintenance schedules. In this...

The rail network in the Netherlands is one of the busiest in Europe. To ensure a safe and reliable infrastructure, preventive maintenance is of utmost importance. ProRail, the sole maintainer of the railway infrastructure in the Netherlands, spends hundreds of millions of dollars on maintenance each year. Due to the complexity and busyness of...

Natural gas has been a significant source of energy for the Netherlands for a long time, but due to developments such as climate change awareness and increased seismic activity in the Groningen area, the Dutch Government has decided to shift away from natural gas and look for alternatives. Hydrogen gas is such a contender, as it can partly use...

In dynamic scheduling, some of the information about the scheduling problem is learnt during the execution of the schedule. Because of this, creating a low cost schedule that does not have to be changed is impossible in most cases. When changes are made during the execution, focussing solely on the performance of the schedule may result in very...

As the use of Networked Control Systems increases, the need for control methods with more efficient network usage also grows. These methods require a more sophisticated way of pre- dicting their traffic, and an approach for this is using a formal modelling approach using Timed Automata. Timed Automata have been used for over 25 years for several...

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...

To cope with the current problems in the construction industry, project managers and scholars seek new methods to turn the tide. Many scholars blame traditional management approaches for cost overruns and delays occurring in current projects. To find solutions, project managers introduce tools from various sectors that have coped with similar...

This research presents an Integrated Production and Distribution Scheduling (IPDS) optimization problem in which the total transportation costs for an online grocer have to be minimized. The production refers to the preparation of orders at the production facility and the distribution is related to the transportation from the production...

This thesis proposes a model for charge scheduling of electric vehicles in last-mile distribution to investigate the impact of charge schedule optimisation on charging cost. A mixed integer problem formulation is proposed that considers labour, battery degradation and time-variable energy cost. The benefit of implementing charge schedule...

Defects that occur on train sets have to be repaired in a repair location and this has consequences on the transportation network. This paper proposes a decision support model that is developed for optimising the decisions of when and where to repair that defect train set. In practice, there is no clear overview of the effects of such decisions...

Hospitals are under an increased financial pressure, due to a significant growth in demand for healthcare, that is caused by an aging population. The operating rooms account for the largest costs of a hospital, and thus require a cost-efficient management. However, scheduling the operating rooms is a complex task that involves the estimation of...

Risk management is undoubtedly a precious component of the overall project management field. It assists in identifying, assessing and mitigating the uncertainties that are present in a project. These uncertainties affect important measures of a project, of which cost and schedule are the most prominent, and consequently put project success under...

In operational airline crew scheduling, one of the major tasks is to allocate flight activities to individual crew members. This task is referred to as the crew rostering problem; an optimization problem that aims to assign flights to crew members in a cost-effective way, while also considering preferences of crewmembers. Flights are combined...

Aircraft base maintenance consists of hundreds of tasks including preventive, corrective and modification tasks which have to be scheduled to a few check moments per year. The allocation of tasks to checks represents a complex scheduling problem due to the constraints involved. A mixed integer linear programming model was developed to optimize...

This thesis investigates the potential of a large pumping station in IJmuiden, the Nether-lands, for participating in Demand Response. Due to climate change, renewable energy is onthe rise. The intermittency of energy, together with its unpredictable supply, are a big hurdlefor the energy transition. Two methods are promising solutions to this...

Roparun is a Foundation that organizes a yearly relay race from Paris, Hamburg and Almelo to Rotterdam in order to raise money for a variety of causes related to palliative care. They requested for an application that could create the start schedule of the race. In this thesis, the problem is analyzed and a greedy based solution is presented....

Mechatronic embedded control systems are becoming increasingly sophisticated and computationally demanding. These systems typically consists of multiple controllers, which coordinate the actuators and apply feedback based on data collected by sensors. Often the underlying control strategy is entirely described in a software application, which...

With cockpit crew costs being the second largest costs of an airline, making optimal use of the available crew is very important. The productivity of the crew is limited by the labor agreement and law regulations, which prevent the crew members from working irregularly or excessively. In this thesis we present several methods to solve the crew...
