  1. 1. Reinforcement learning for train dispatching : A study on the possibility to use reinforcement learning to optimize train ordering and minimize train delays in disrupted situations, inside the r ail simulator OSRD

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

    Författare :Teodora Popescu; [2022]
    Nyckelord :;

    Sammanfattning : Train dispatching is a complex process, especially when the train traffic is disrupted, as the decisions taken by the dispatchers can have substantial consequences on the delays of the trains. The most frequent dispatching decisions consists in changing the order of trains at convergence points, where two tracks unite to become a single track. LÄS MER

  2. 2. Study of an automated testing procedure with dynamic job scheduling and automatic error handling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Tom Andersson; [2021]
    Nyckelord :Automation; Testing; Dynamic job scheduling; Automatic error handling; Concept generation; Heuristic rules; Dispatching rules; Branch and bound; A*; Dynamic programming; Beam search; Genetic algorithms; Tabu search; Simulations; C#; Technology and Engineering;

    Sammanfattning : During the production of Axis's cameras, the optics modules have to do a number of tests and calibrations that are performed in different test stations. The test and calibration sequence differs between different models. This has so far been done manually by having operators move the units between test stations. LÄS MER

  3. 3. Modeling ambulance dispatching rules for EMS-systems

    Kandidat-uppsats, KTH/Optimeringslära och systemteori

    Författare :Lorinde Knoops; Tilda Lundgren; [2016]
    Nyckelord :Ambulance dispatching; Ambulance logistics; Emergency medical services; Priority-based dispatching rules; Markov process; Professional competencies; Ambulansdirigering; Ambulanslogistik; Prehospital sjukvård; Prioritets-baserade dirigeringsstrategier; Markovprocess; Yrkeskunnande;

    Sammanfattning : This thesis presents a study on efficient dispatching rules in ambulance dispatching. By efficient dispatching rules, we mean such dispatching rules that lower response times for priority 1 calls while keeping response times for priority 2 calls at an adequate level. LÄS MER

  4. 4. A behavioral model of solar/diesel/Li-ion hybrid power systems for off-grid applications : Simulation over a lifetime of 10 years in constant use

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Gordon Gaudray; [2015]
    Nyckelord :Hybrid power plant; off-grid; renewable; Li-ion battery; dispatching strategy; battery aging; modelling; Matlab; Simulink;

    Sammanfattning : Remote hybrid power systems (RHPS) serve local off-grid loads or various island grids when no grid extension is possible. They combine renewable resources, conventional generators and energy storage systems in order to balance the load at any moment, while ensuring power quality and energy security similar to large centralized grids.

  5. 5. Industrial scheduling with evolutionary algorithms using a hybrid representation

    Magister-uppsats, Institutionen för teknik och samhälle

    Författare :Martin Andersson; [2011]
    Nyckelord :scheduling; optimisation; simulation;

    Sammanfattning : Scheduling problems have been studied extensively in the literature but because they are so hard to solve, especially real-world problems, it is still interesting to find ways of solving them more efficiently. This thesis aims to efficiently solve a real-world scheduling problem by using a hybrid representation together with an optimisation algorithm. LÄS MER
