  1. 1. Markov Chains as a Real-time System Monitoring Service : Numerical Repair Rate Optimization (RRO)

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Emil Carmegren; [2022]
    Nyckelord :Markov Chains; Dependability Evaluation; Probability Theory;

    Sammanfattning : The expansion and increased complexity of technology is undoubtedly consistent and one can intuitively suppose that this trajectory will not deviate from this course in the years to come. On a continuous basis, concepts that started of as some hypothetical or abstract notions without practical relevance gets transferred to the modern state of our current technology. LÄS MER

  3. 2. Developing Markov chain models for train delay evolution in winter climate

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Frej Sundqvist; [2021]
    Nyckelord :Markov chains; Train delay;

    Sammanfattning : The traffic on Swedish railways is increasing and punctuality is of important matter for both passenger and freight trains. The problem of modeling train delay evolution is complex since conflicts between trains can occur and since a delay can have a wide variety of causes. Swedish railways faces in addition harsh winter climate. LÄS MER

  4. 3. Quantified safety modeling of autonomous systems with hierarchical semi-Markov processes

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Olle Mattsson; [2020]
    Nyckelord :probability theory; stochastic processes; reliability engineering; applied mathematics; quantified safety; markov processes; markov chains; sannolikhetsteori; stokastiska processer; säkerhetsteknik; tillämpad matematik; markovprocesser; markovkedjor;

    Sammanfattning : In quantified safety engineering, mathematical probability models are used to predict the risk of failure or hazardous events in systems. Markov processes have commonly been utilized to analyze the safety of systems modeled as discrete-state stochastic processes. LÄS MER

  5. 4. Modelling of Safety Concepts for Autonomous Vehicles using Semi-Markov Models

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Carl Bondesson; [2018]
    Nyckelord :Semi-Markov processes; continuous-time Markov chains; safety; steady-state distribution; dependability; ISO 26262;

    Sammanfattning : Autonomous vehicles is soon a reality in the every-day life. Though before it is used commercially the vehicles need to be proven safe. The current standard for functional safety on roads, ISO 26262, does not include autonomous vehicles at the moment, which is why in this project an approach using semi-Markov models is used to assess safety.

  7. 5. Estimating Probability of Default Using Rating Migrations in Discrete and Continuous Time

    Master-uppsats, KTH/Matematisk statistik

    Författare :Rickard Gunnvald; [2014]
    Nyckelord :;

    Sammanfattning : During the financial crisis that began in 2008, even whole countries and very large companies defaulted or were on the verge of defaulting. The turmoil made risk managers and regulators more vigilant in scrutinising their risk assessment. LÄS MER
