  1. 1. Godsplacering för minskad körsträcka i en intermodal terminal : En studie om att optimera placering av gods hos SCA Logistics

    Kandidat-uppsats, Mittuniversitetet/Institutionen för kommunikation, kvalitetsteknik och informationssystem (2023-)

    Författare :Erik Edvall Ung; [2023]
    Nyckelord :Intermodal terminal; linear programming; inventory management; goods placement; transportation problem; optimization.; Intermodal terminal; linjärprogrammering; lagerhantering; godsplacering; transportproblem; optimering.;

    Sammanfattning : The placement of goods is considered an important aspect to minimize mileage, which reduces costs and the amount of environmentally hazardous emissions. In this case study with a quantitative approach, the aim was to optimize the placement of goods in an intermodal terminal to minimize the distances between its warehouses and the different delivery approaches for current and future operations.

  3. 2. Optimization of Collateral Allocation for Corporate Loans : A nonlinear network problem minimizing the expected loss in case of default

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Sofia Grägg; Paula Isacson; [2022]
    Nyckelord :Nonlinear optimization; network problem; transportation problem; Markowitz; credit risk; Loss Given Default; Loan to Value; collateral management; many-to-many relations; modern portfolio theory; expected loss; risk management; optimization; allocation; portfolio; modeling; Icke-linjär optimering; nätverksproblem; transportproblem; Markowitz; kreditrisk; förlust givet fallisemang; belåningsgrad; säkerhetshantering; många-till-många relationer; modern portföljteori; förväntad förlust; riskhantering; optimering; allokering; portfölj; modellering.;

    Sammanfattning : Collateral management has become an increasingly valuable aspect of credit risk. Managing collaterals and constructing accurate models for decision making can give any lender a competitive advantage and decrease overall risks. LÄS MER

  4. 3. Stochastic Lateral Transshipment within the Fast Fashion Industry

    Master-uppsats, KTH/Matematik (Inst.)

    Författare :Linnéa Andersson; [2022]
    Nyckelord :Degree Project; Fast Fashion; H M; Lateral Transshipment; Linear Optimization; Master’s Thesis; Recourse Problem; Retail; Sample Average Approximation; Stochastic Optimization; Transshipment; Two-Stage Recourse Problem; Detaljhandel; H M; Lagerflyttar; Lagerhantering; Linjär optimering; Masters Examensarbete; Mode; Optimering; Snabbt mode; Stokastisk optimering; Transportproblem;

    Sammanfattning : In an industry with highly variable demand and a fickle customer demanding a fast changing supply, quickly responding to the customer becomes crucial for the fast fashion retailer. Using lateral transshipment, one is able to reorganize supply within an echelon of the supply chain to quickly respond to the forecasted demand by looking at shorter more accurate forecasts and act accordingly.

  5. 4. An Optimization Model for Electric Vehicle Routing with Tractor Swapping

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Alexander Strid; Daniel Liu; [2022]
    Nyckelord :Vehicle Routing Problem VRP ; tractor swapping; electric VRP; rich VRP; heavy goods vehicles; mixed-integer linear programming MILP ; applied mathematics; ruttoptimering; traktorbyte; elektriska lastbilar; tunga lastbilar; linjär heltalsoptimering; tillämpad matematik;

    Sammanfattning : The purpose of this thesis is to investigate how tractor swapping can be implemented in Vehicle Routing Problems (VRP) with electric heavy goods vehicles, and to evaluate how a model that allows for tractor swapping performs, in terms of schedule cost, against a model that does not. Hence, this thesis introduces a new rich VRP variant which includes tractor swapping, as well as time windows, pickup and delivery, and electric vehicles. LÄS MER

  7. 5. Investigation on Operation of the Compact Molten Salt Reactor by Modelling the Primary Circuit in GeN-FOAM

    Master-uppsats, KTH/Fysik

    Författare :Jelle Oving; [2022]
    Nyckelord :molten salt reactor; GeN-Foam; delayed neutrons; OpenFOAM; multi-physics; smältsaltreaktor; GeN-Foam; fördröjda neutroner; OpenFOAM; multifysik;

    Sammanfattning : In recent years there has been a revision of the molten salt nuclear reactor concept for production of power. Moving of fissile material throughout the primary circuit for these types of reactors creates the necessity of novel physics solvers to study movement of delayed neutron precursors, plant operation, accident scenario's; crucial for design.
