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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  3. 2. Efficiently Solving the Exact Cover Problem in OpenMP

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Leo Hall; [2023]
    Keywords : Exact Cover; openmp; parallelization;

    Abstract : The exact cover problem is an NP-complete problem with many widespread use cases such as crew scheduling, railway scheduling, benchmarking as well as having applications in set theory. Existing algorithms can be slow when dealing with large datasets however. READ MORE

  4. 3. An ILP-model for the Train platforming problem

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Simon Calderon; [2023]
    Keywords : Optimization; Integer programming; Train platforming; Train scheduling; Optimering; Heltalsprogrammering; Tåg; Järnväg; Schemaläggning;

    Abstract : The goal of this thesis is to create an optimization model to optimize the routing of trains within railway stations. This problem is known as the train platforming problem, and the model we present is an integer programming model. By this model we aim to optimize factors such as walking distance, switch usage or platform usage. READ MORE

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

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

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

    Abstract : 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.

  6. 5. Optimization of the Onboard Computer

    University essay from KTH/Matematik (Avd.)

    Author : Alexej Filinau; [2022]
    Keywords : ;

    Abstract : As the population is growing, the need for sustainable and safe mobility solutions increases. The evolution of technology within the railway industry is crucial for a more connected world. Hence, it is important to potimize the Automatic Train Protection, ATP, to ensure that high-speed trains remain fast and safe. READ MORE
