  1. 1. Challenges in the Maintenance and Diagnostic Segment of Digital Asset Management in the Swedish Railway Industry

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Salam Adeeb; Marwan Ouali; [2023]
    Nyckelord :Railway Digital Asset Management; remote monitoring; condition-based maintenance; predictive maintenance; Digital tillgångsförvaltning; prediktivt underhåll; tillståndsbaserat underhåll; diagnostik;

    Sammanfattning : Just like the rest of society, the use of digital technology has throughout the years become a more crucial part for train companies to improve performance, meet customer demands, improve operation and maintenance processes to increase efficiency and reliability. These solutions have through time developed to become part of a cluster named Digital Asset Management (DAM). LÄS MER

  3. 2. Simultaneous scheduling of railway maintenance and trains : Modelling and solving train interactions close to a maintenance operation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Pauline Vaillant; [2023]
    Nyckelord :Optimization; Linear programming; Heuristics; Railway scheduling; Maintenance planning; Optimering; Linjärprogrammering; Heuristik; Järnvägsplanering; Underhållsplanering;

    Sammanfattning : Rail transport plays a key role in the mobility of passengers and goods. It is expected to grow the decarbonization of society. In that context, it is important to use the railway network efficiently, and jointly planning trains and network maintenance allows for better use of resources. LÄS MER

  4. 3. En grönare järnväg

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

    Författare :Peder Winblad; [2023]
    Nyckelord :Järnväg; Greenwashing; Emissioner; Klimatsmart; Miljöarbete; Utsläppsberäkning; Pedagogik; Miljöförorening; Formelutveckling; Banvall; Räls; Sliper; CO2; Technology and Engineering;

    Sammanfattning : Detta arbete är en utredning av hur järnvägskonstruktionens emissioner ser ut vid anläggning. Den samlade datan har översatts i ett matematiskt uttryck som ger ett minsta årtal för när en neutraliseringshorisont för projektet kan nås. LÄS MER

  5. 4. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Rui Zhou; [2023]
    Nyckelord :;

    Sammanfattning : This research aims to investigate accurate classification of anomalous vibrations produced during vehicle operation. The main research questions are which data can be used as classification criteria, which models can better achieve classification effects, and how to address classification issues under different variables in a car.

  7. 5. Holistic embedding of equivalent conicity in wheelset maintenance

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Philipp Linzbichler; [2023]
    Nyckelord :Railway Operation; Equivalent Conicity; Wheelset Maintenance; Smart Maintenance; Data Analysis; Järnvägsdrift; Ekvivalent Konicitet; Hjulset Underhåll; Smart Underhåll; Dataanalys;

    Sammanfattning : With continuing digitization of railways an increasing number of data is recorded but particularly in operation advanced analysis tends to be partially rudimentary. Yet, it is essential to implement sophisticated processing for all records in order to develop more purposeful and predictive vehicle maintenance strategies that adhere to the increasing requirements imposed by the homologation.
