  1. 1. Periodical Maintenance Modelling and Optimisation Assuming Imperfect Preventive Maintenance and Perfect Corrective Maintenance

    University essay from KTH/Optimeringslära och systemteori

    Author : Madeleine Engvall Birr; Lisette Lansryd; [2021]
    Keywords : Master Thesis; Maintenance Management; Maintenance Modelling; Imperfect PM; Perfect CM; Periodic Policy; Genetic Algorithms; Age Reduction; Masterexamensarbete; Underhållsarbete; Underhållsmodellering; Ofullständiga FU; Perfekta AU; Periodisk Planläggning; Genetiska Algoritmer; Åldersreduktion;

    Abstract : In this paper, a periodic maintenance model is formulated assumingcontinuous monitoring, imperfect preventive maintenance (PM) and perfect correctivemaintenance (CM) using three decision variables, (I, N, Z). The model is derived in aninfinite horizon context where the mean cost per unit time is modelled. READ MORE

  3. 2. A Comparative Study on a Dynamic Pickup and Delivery Problem : Improving routing and order assignment in same-day courier operations

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

    Author : Tomas Andersson; [2021]
    Keywords : Pickup and Delivery; Dial-a-Ride; Dynamic; Order assignment; Large Neighborhood Search; Pickup and Delivery; Dial-a-Ride; Dynamisk; Tilldelning av beställningar; Large Neighborhood Search;

    Abstract : Pickup and Delivery Problems (PDPs) constitute a class of Vehicle Routing Problems (VRPs) consisting of finding the optimal routes for a fleet of vehicles to deliver requests from a set of origin locations to a corresponding set of destinations. PDPs are NP-hard and have a wide variety of variants and potential constraints. READ MORE

  4. 3. Informative path planning for algae farm surveying

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

    Author : Corentin Guy Claude Chauvin-Hameau; [2020]
    Keywords : ;

    Abstract : Algae farms need to be regularly monitored to control growth rate or check for signs of diseases. As marine farms are setup farther from the coasts, the need for developing robots capable of carrying out these tasks autonomously increases. This thesis investigates trajectory generation for an underwater robot monitoring an algae farm. READ MORE

  5. 4. Hierarchical Dynamic Games for Human-Robot Interaction with Applications to Autonomous Vehicles

    University essay from KTH/Matematik (Avd.)

    Author : Elis Stefansson; [2018]
    Keywords : ;

    Abstract : The deployment of autonomous vehicles has become an active area of research due to its potential solution as a more efficient and intelligent transportation system. While early research focused on isolated systems, autonomous vehicles integrated on public roads have lately received substantial attention. READ MORE

  6. 5. Formulering och utvärdering av renskötselanpassad skogsskötsel med integrerad geografisk information från beteslandsindelning

    University essay from SLU/Dept. of Forest Resource Management

    Author : Adam Lundström; [2016]
    Keywords : ren; samråd; samrådsunderlag; renskötsel; landskapsperspektiv; renskötselanpassad skogsskötsel; Heureka PlanVis;

    Abstract : Rennäringen och skogsnäringen verkar inom samma geografiska område. För renskötseln är vinterbetet en flaskhals där tillgången till marklavsbete är avgörande. Sedan introduktionen av trakthyggesbruk under 1950-talet i Sverige så har arealen skogsmark av lavtyp (>50% lavtäckning) minskat med 71 %. READ MORE
