16. Skyddsavstånd på järnväg. Behov av regelförändringar vid ändrade förutsättningar.
Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och vägSammanfattning : Dagens signalregelverk ställer krav på en minsta längd för reserverat spåravsnitt bortom slutpunkt för rörelseväg till ett annat fordon i rörelse. Detta kallas för skyddsavstånd och krav som ställs på dess längd gör det möjligt att tillåta samtidiga rörelser på en driftplats vilken har positivt påverkan på kapaciteten. LÄS MER

18. Uncertainty quantification for neural network predictions
Magister-uppsats, Umeå universitet/StatistikSammanfattning : Since their inception, machine learning methods have proven useful, and their usability continues to grow as new methods are introduced. However, as these methods are used for decision-making in most fields, such as weather forecasting,medicine, and stock market prediction, their reliability must be appropriately evaluated before the models are deployed.

19. Stochastic Goal Programming of Supply Chain under Disruption
Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)Sammanfattning : The spread of COVID-19 pandemic in the world and the importance of controlling it in all regions have made managing this crisis a great challenge for all countries. The devastating effect on global automotive supply chains due to the disruptions has resulted in losses and shut down of production facilities owing to government restrictions due to the spread of infections leading to supply breakdown across all tiers of supply chain.

20. The Relationship Between Vertical Integration and Risk. A Statistical Analysis of Changes in Vertical Integration within Industries Affected by the Global Semiconductor Shortage
Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionenSammanfattning : Succeeding a brief discussion of what vertical integration (VI) is, its interaction with risk and uncertainty, and the context of this study, namely the COVID-19 pandemic and its simultaneous semiconductor shortages, the purpose of this paper is outlined to fill a research gap regarding an empirically supported relationship between vertical integration and systemic risk. The aim and contribution here is subsequently twofold: to examine whether one can predict strategic trends and behavior among multinational companies when it comes to value chain ownership and control decisions in response to abnormal levels of systemic risk, and, to more generally statistically prove or disprove the seeming theoretical consensus that vertical integration can be a key risk-reduction strategy for various reasons, something that will be detailed and explored more closely in an extensive literature review.
