Smart Grid scheduling problems are characterized by quickly changing situations and multiple external factors that cannot be controlled. Most smart grid research applies stochastic models over the total power consumption of a household or system to find a schedule that achieves an optimization, a balancing, or constraint satisfaction. While...

Efficient reasoning about time is crucial for robot operation, planning, and many other applications. A widespread representation used for reasoning about time is the so-called Simple Temporal Network (STN). Students at TU Delft previously developed and implemented algorithms for performing incremental reasoning over STNs. These algorithms...

The multi-mode resource-constrained project scheduling problem (MRCPSP) is an NP-hard scheduling problem that concerns activities with several execution modes connected by precedence relations. Precedence relations define a partial ordering in which activities must be processed. The execution mode of an activity defines its processing time and...

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...

Scheduling is required in almost every industry and when done well it can bring a lot of revenue. Flexibility is often forgotten when creating the initial schedules. Therefore, in case of an unexpected delay, the whole schedule has to suffer. In this paper, we consider a re-entrant flow shop with sequence-dependent setup times and relative due...

The execution of multi-inference tasks on low-powered edge devices has become increasingly popular in recent years for adding value to data on-device. The focus of the optimization of such jobs has been on hardware, neural network architectures, and frameworks to reduce execution speed. However, it is yet not known how different scheduling...

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....

Industrial companies aim for optimizing profit from delivering project outcomes. Maximizing profit relies on optimization of using resources, production capacity and available time. To reach this goal, companies are typically reliant on planning and production schedules. This problem is known as the project portfolio selection and scheduling...

In this thesis, the design and implementation of a wireless communication module and an accompanying network are discussed. This wireless communication module is used in a device which communicates frost temperatures measured at orchards. The goal is to gather data on how fruit frost develops on orchards, and to warn a fruit farmer if it starts...

This paper solves job sequencing with one common and multiple secondary resources (JSOCMSR) problem by encoding it as a Boolean satisfiability (SAT) problem and applying domain-specific heuristics to improve the SAT solver’s performance. JSOCMSR problem is an NP-hard scheduling problem where each job utilizes two resources: a shared resource and...

The multi-mode resource-constrained project scheduling problem (MRCPSP) is an extension of the resource-constrained project scheduling problem (RCPSP), which allows activities to be executed in multiple modes. The state-of-the-art solutions for solving this NP-Hard problem are dedicated algorithms and (meta-)heuristics. However, this paper...

Surgical scheduling is a complex task that requires consideration of various factors, including the probability of overtime. In this study, we address the research problem of surgery scheduling while accounting for the likelihood of exceeding scheduled operating room (OR) time. To tackle this problem, we employ integer linear programming (ILP)...

The majority of the courses in the Computer Science Bachelor at the Delft University of Technology use so called lab sessions to provide an opportunity for students to ask questions about course material and get feedback on their assignment. In order to optimally support the students, teaching assistants, or TAs, are appointed to assist the...

The MRO market currently spans around 9.5% of the total operating cost of an airline. Of this, 70% is covered by heavy-maintenance. Reduction of these costs and improving efficiency could, therefore, be significant for an airline. A possible solution is the optimization of the long-term schedule of heavy-maintenance checks. Current approaches...

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...

The volatile production of renewable energy sources is often considered a key issue in future sustainable energy systems. Drawing on microgrid research, we argue that the potential synergy between microgrid energy management and provision of flexibility services to the wider grid could be further explored. In addition, the trade-off between cost...

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...

Synchronous systems waste a lot of power in the clock tree, and must be designed based on the worst case scenario in terms of speed. Asynchronous circuits offer relief to these problems, by replacing clock signals with handshakes which only charge when data is being transferred, and delay signals which may adapt more easily to variance in speed...

This Thesis proposes an optimisation model to minimize operational cost of a fleet of electric thin-haul aircraft under a minimum RPK (Revenue-Passenger Kilometer) constraint. A solution that minimises cost per RPK can be found by varying the minimum RPK level. The solutions describes how many aircraft are needed, as well as a schedule for each...

Efficient management and propagation of temporal constraints is important for temporal planning as well as for scheduling. During plan development, many solvers employ a heuristic-driven backtracking approach, over the course of which they maintain a so-called Simple Temporal Network (STN) of events and constraints. Recent research has shown...
