Benders decomposition-based optimization of train departure frequencies in metro networks

Timetables determine the service quality for passengers and the energy consumption of trains in metro systems. In metro networks, a timetable can be made by optimizing train departure frequencies for different periods of the day. Typically, the optimization problem that arises from optimizing train departure frequencies in metro networks...

Smart grid-integrated vessel through a shore power system

Battery energy storage systems (BESS) that are integrated with the electricity grid have proven to be a suitable solution for reducing costs by providing flexible demand, but are often uneconomical when used solely for this purpose. Despite the research efforts showing the benefits of an energy-integrated harbor-area smart grid (HASG), the...

Dynamic Capacity Allocation for Optimal Revenue Management: A ULCC Data Driven Case Study

In the airline industry revenue and inventory is managed tightly, with the intent to sell each seat at the right price to the right customer at the right time. This does not always go to plan and seats remain unsold, or demand can be greater than what is available. The question then becomes how can capacity and revenue be managed more...

Routing and scheduling of maintenance support vessels for an offshore wind and solar farm

Floating photovoltaic (FPV) is an emerging concept. Potential is recognized in combining FPV and off­ shore wind farms to create an offshore wind and solar farm. One of the remaining uncertainties around the potential of an offshore wind and solar farm is the value of the operations and maintenance cost. As one of the main contributing factors...

Network restructuring as a way to mitigate project delays: A multicriteria and optimization approach for network restructuring as a strategy to mitigate project delays in large infrastructure projects; an alternative perspective on the Mitigation Controller

Purpose - This development project is focused on the combination of project scheduling and risk mitigation for large infrastructure projects. The aim of this project is to develop a model that can automatically restructure the network schedule to enable that delay is mitigated as much as possible while the effects on multiple project criteria...

Parallel Machine Scheduling: with Partition Constraints

Optimization of the maintenance scheduling and production valuation by green certificates

Summary Part I - Optimization of the maintenance scheduling Resource management in the industry is an important feature to make the most of the production, particularly in maintenance field where the availability of people is a very important condition to minimize losses. An optimized maintenance scheduling is of a crucial importance for wind...
