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. Randomized heuristic scheduling of electrical distribution network maintenance in spatially clustered balanced zones

   University essay from KTH/Geoinformatik

   Author : Carolina Offenbacher; Ellen Thornström; [2022]
   Keywords : Capacitated Vehicle Routing Problem; Electrical distribution network; Heuristic algorithm; Scheduling; Handelsresandeproblemet; Eldistributionsnätverk; Heurustik algortim; Schemaläggning;

   Abstract : Reliable electricity distribution systems are crucial; hence, the maintenance of such systems is highly important, and in Sweden strictly regulated. Poorly planned maintenance scheduling leads unnecessary driving which contributes to increased emissions and costs. READ MORE

4. 3. Improving maintenance scheduling with condition monitoring on the electric distribution grid : An economic analysis comparing corrective and predictive maintenance

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

   Author : Hugo Vincenti; [2022]
   Keywords : Condition-based maintenance; predictive maintenance; health index; failure rate; maintenance scheduling; sensors; economic analysis; simulation; Tillståndsbaserat underhåll; förebyggande underhåll; hälsoindex; felfrekvens; underhållsplanering; sensorer; ekonomisk analys; simulering.;

   Abstract : A growing use of sensors on the electric grid has opened the door to new methods of asset management: Distribution System Operators are now looking into conditionbased maintenance, as opposed to the traditional corrective or time-based methods. As an emerging field, the methodology must be constructed from the ground, with the little data available. READ MORE

5. 4. General-purpose maintenance planning using deep reinforcement learning and Monte Carlo tree search

   University essay from Linköpings universitet/Artificiell intelligens och integrerade datorsystem

   Author : Viktor Holmgren; [2019]
   Keywords : Machine learning; MCTS; AI; Maintenance planning;

   Abstract : Maintenance planning and execution is increasingly important for the modern industrial sector. Maintenance costs can amount to a major part of industrial spending. However, it is not as simple as just reducing maintenance budgets. READ MORE

6. 5. Modeling fault probability in single railroad turnouts in Eastern Region, Sweden, with the use of logistic regression models : A step from preventive to predictive preventive maintenance in railway maintenance planning

   University essay from KTH/Transportplanering

   Author : Filipp Zarov; [2019]
   Keywords : maintenance planning; railway turnouts; malfunction probability modeling; object-oriented databases; logistic regression models; underhållsplanering; spårväxlar; felsannolikhet modellering; objektorienterad databas; logistiska regressionsmodeller;

   Abstract : Turnouts are an important part of railway infrastructure for two reasons: infrastructure andmaintenance. For the infrastructure they provide the flexibility to allow the formulation and branchingof railway network and for maintenance they consume a large part of maintenance budget and have aprominent place in maintenance planning policy and activities.
