This study examines the effect of seat assignment strategies on the transfer time of connecting passengers at a hub airport. Passenger seat allocation significantly influences disembarkation times, which can increase the risk of missed connections, particularly in tight transfer situations. We propose a novel seat assignment strategy that allocates seats to nonpaying passengers after check-in, prioritising those with tight connections. This approach diverges from traditional methods focused on airline turnaround efficiency, instead optimizing for passenger transfer times and reducing missed connections. Our simulation, based on real-world data from Paris-Charles de Gaulle airport, demonstrates that this passenger-centric model decreases missed connections by 12%, enhances service levels, reduces airline compensation costs, and improves airport operations. The model accounts for variables such as seat occupancy,luggage, and passenger type (e.g., business, leisure) and is tested under various scenarios, including air traffic delays.

From a circular standpoint it is interesting to reuse as much as possible construction and demolition waste (CDW) into new building projects. In most cases CDW will not be directly reusable and will need to be processed and stored first. In order to turn this into a successful business case CDW will need to be reused on a large scale. In this paper we present the concept of a centralized and coordinated location in the City of Utrecht where construction and demolition waste is collected, sorted, worked, stored for reuse, or shipped elsewhere for further processing in renewed materials. This has expected advantages for the amount of material reuse, financial advantages for firms and clients, generating employability in the logistics and processing of materials, optimizing the transport and distribution of materials through the city, and thus the reduction of emissions and congestion. In the paper we explore the local facility of a Circular Hub, and the potential effects on circular reuse, and other effects within the City of Utrecht.
Als invulling voor de City Deal Kennis Maken willen de gemeente Leeuwarden en de onderwijsinstellingen (MBO, HBO en WO) in nauwe samenwerking met bedrijfsleven en maatschappelijke instellingen hun krachten bundelen voor het oplossen van relevante vraagstukken. De stad heeft gezien de rurale context in Noord-Nederland een brede definitie, onder het motto “De Stad als campus, de regio als proeftuin”. De uitgangspunten zijn: - Er wordt in eerste instantie gewerkt aan thema’s en uitgangspunten vanuit de Kennisagenda Fryslân die vanuit het Hoger Onderwijs Akkoord Fryslân, naar een innovatieve en lerende regio is opgesteld, - De uitdagingen worden aangepakt vanuit een multi-disciplinaire en multi-level (MBO, HBO en WO) aanpak. - De activiteiten vinden zoveel mogelijk plaats in zogenaamde living labs . - Het Innovatie Pact Fryslân, een samenwerkingsverband tussen het Friese hoger onderwijs, het beroepsonderwijs, het bedrijfsleven, de provincie Fryslân en de F4 gemeenten en Hoger Onderwijs Akkoord Fryslân overleg (zie figuur 2) als strategisch platform inzetten. In algemene zin de activiteiten die in dit kader uitgevoerd gaan worden zijn: 1. Het aanstellen van een kwartiermaker/ kennismakelaar die maatschappelijke vraagstukken in kaart brengt en kan koppelen aan de partners. 2. Als pilot, het inrichten van een aantal living labs op basis van een multi-disciplinaire- en multi-level aanpak. Studenten van meerdere kennisinstellingen en verschillende opleidingen zullen hieraan deelnemen om meerdere invalshoeken te krijgen om de maatschappelijke uitdagingen aan te pakken. Als hoogtepunt zal er een groot inspiratie-event georganiseerd worden (“Fryslân breekt uit”). 3. Het opstellen van een gezamenlijke living lab agenda, waarin gewerkt wordt aan de afstemming en uitvoering van de living labs. NHL Stenden Hogeschool zal als penvoerder optreden en met de gemeente Leeuwarden als consortiumpartners aan te merken. Daarnaast zullen de O3 partners (onderwijs/onderzoek/ondernemers) verenigd binnen het IPF een belangrijke rol krijgen voor afstemming, maar ook in de uitvoer.
In 2021, Citython editions were held for the European cities of Eindhoven (Netherlands), Bilbao and Barcelona (Spain), Hamburg (Germany), and Lublin (Poland). Within this project, BUAS contributed to the organization of CITYTHON Eindhoven in cooperation with CARNET (an initiative by CIT UPC) and City of Eindhoven – an event which gives young talent the opportunity to work with mentors and experts for the development of innovative urban solutions. Participants of CITYTHON Eindhoven worked on three challenges:- Traffic safety in school zones - Travel to the campus- Make the city healthy The event took place between 18 May and 2 June 2021 with various experts, for example from ASML, City of Eindhoven and University of Amsterdam, giving inspirational talks and mentoring students throughout the ideation and solutions development process. The teams presented their solutions during the Dutch Technology Week and the winners were announced by Monique List-de Roos (Alderman Mobility and Transport, City of Eindhoven) on 2 June 2021. The role of BUAS within this project was to assist City of Eindhoven with the development of the challenges to be tackled by the participating teams, and find relevant speakers and mentors who would be supporting the students for the development of their solutions and jury members who would determine the winning teams. The project ended with a round table “Green and Safe Mobility for all: 5 Smart City(thon) Case studies” on November 17 organized as part of Smart City Expo World Congress 2021 in Barcelona. This project is funded by EIT Urban Mobility, an initiative of the European Institute of Innovation and Technology (EIT), a body of the European Union. EIT Urban Mobility acts to accelerate positive change on mobility to make urban spaces more livable.

In 2017, renowned Prof Kate Raworth from Oxford University and Amsterdam University introduced Doughnut Economics, an economic model to enable humans to thrive within the planetary boundaries and resources. Several private and public actors, including the city of Amsterdam, adopted the model in their circular economy development's strategies. Doughnut-Architecture aims to develop further the AREA (Atelier for Resilient Environmental Architecture) Framework, a tool designed by graduating students Charlotte Uiterwaal, Isabella van der Griend, Ryan McGaffney, Karolina Bäckman, at the faculty of Architecture, Delft University of Technology (TU-Delft), under the supervision of Henri van Bennekom. AREA-Framework support architects to intervene in the built environment taking as a reference the Doughnut Economics model. The AREA-Framework is at an initial stage, and its categories and subcategories are only qualitative. TU-Delft, the architectural practices Space&Matter and SuperuseStudios, in collaboration with the interdepartmental research group Circular Built Environment Hub (CBEH) and architectural practices from the network of 400 construction companies belonging to the Ex'tax project, the advice from Kate Raworth and the Amsterdam-Donut-Coalitie will further develop the AREA-Framework primarily quantitatively and also qualitatively. TU-Delft, Space&Matter, SuperuseStudios, other architectural practices from the Ex'tax-network will test the framework on different phases of real projects, interdepartmental research and education. The ultimate goal is to develop the framework further, to increase the number of architectural practices successfully implementing the Doughnut Economics in the built environment at a national level. The framework will contribute to positioning the architectural practices concerning Doughnut Economics and the Circular Economy. The project results are firstly an online open-access publication about the further developed Framework to be applied by architects; secondly, the preparation and submission of a follow-up research proposal about the extended development and implementation of the Framework applicable to the built environment by all the Ex'tax construction sector companies.
