Improving Railway Punctuality: A Comparative Multi-Criteria Analysis of Solutions Across Six Nations
(2025) Ek, Ludvig; Gkaintatzis , Theodoros
This project is a part of a master’s program course named “Project in Railway Technology”, with 7.5 ECTS credits. The report analyzes the issue of punctuality of railways in six nations – Sweden, Greece, Japan, Finland, Germany and France – and observes the massive variations between the quality of infrastructure, operating efficiency and investment. It evaluates three principal solutions to improve punctuality: enhancing from single to double tracks, running dedicated high-speed trains, and timetabling. In a Multi-Criteria Decision Analysis (MCDA), the report compares these approaches in terms of cost, safety, capacity and time to implement, taking into consideration the perspective of various stakeholders, such as rail operators and travelers. The findings of the MCDA suggest that while investments in infrastructure guarantee longer term benefits, timetabling is a cheap and simple measure to adopt in order to increase punctuality. It concludes that railway punctuality must not only be improved through technical aspect, but also through strategic planning and cooperation of stakeholders.
Synthesis and performance assessment of nanofibrous oxygen carriers in chemical looping dry reforming of methane
(2025) Sandell, Erik
Chemical looping technology is an interesting method of utilizing carbonaceous fu els while alleviating some of the environmental impacts of its usage. It has been
previously implemented in combustion processes and further research is being con ducted to investigate its potential in other processes such as methane reformation.
For chemical looping technology to be viable in this application there is a need for
efficient oxygen carrying materials. This thesis aimed to synthesize and test an
oxygen carrying material with a nanofibrous structure which could be used in dry
methane reformation applications. Using electrospinning, a substrate of was synthe sized on which metals could be impregnated resulting in a nanofibrous material with
metal oxides bound to an alumina fibrous substrate. The metals investigated in this
project was iron, cerium, manganese, strontium and nickel. These materials were
chosen due to their relative abundance and iron was the main metal constituent of
the materials, while the other metals was used as dopants. The resulting materials
were used in methane reformation successfully, with iron-nickel and iron-Strontium
being the most effective of the materials investigated.
Project management in tenant customization: A case study on collaboration, flexibility, and the future Office
(2025) Niemer, Jakob; Schulz, Edvin
This study explores how project management can support flexible tenant
customizations that align with future office trends. Through a qualitative case study in
collaboration with the consultancy firm Tenant & Partner, the research investigates the
role of the project manager in facilitating collaboration, communication, and
adaptability in customization projects. The findings show that early involvement of
stakeholders, clear communication, and a shared understanding of goals between
property owners and tenants are critical to achieving successful outcomes. The study
also emphasizes the importance of aligning contractual agreements between the
property owner, tenant, and construction contractor to ensure a smooth process. Overall,
the report highlights the project manager’s central role in balancing different
stakeholder interests and guiding the customization process toward solutions that
support both current needs and future flexibility.
Enhancing BIM quality through information validation: Exploring the effectiveness of information delivery specification (IDS) in the Swedish construction industry
(2025) Pusa, Linn; Frendberg, Clara
The full potential of BIM is rarely fulfilled, due to the information gap between
the design and construction phases and the design and management. To increase
the reliability of BIM models, buildingSMART created the Information Delivery
Specification (IDS), a standard to structure and specify information requirements.
The full potential of IDS has not yet been demonstrated due to limited knowledge,
awareness, and adaptation, highlighting the need to investigate how IDS can be
implemented to obtain higher-quality BIM models. Drawing on qualitative data
from interviews and observations from testing IDS in old projects, conclusions on
advantages, challenges, and potential improvements associated with the use of IDS
have been determined. The results show that current methods of validating infor mation requirements are incomplete as many requirements are not fulfilled. The
findings show that IDS is an effective tool to automatically validate information
requirements and achieve a higher quality of BIM data. This supports the use of
the BIM model during the building’s whole lifecycle. The study also shows the need
for increased knowledge and awareness of the benefits of IDS to support broader
adoption in the industry. Standardized requirement specifications and classification
are also necessary for smoother implementation.
