    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

  3. 2. Optimal Multi-Skilled Workforce Scheduling for Contact Centers Using Mixed Integer Linear Programming : A Method to Automatize Workforce Management

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Sara Eriksson; [2020]
    Nyckelord :Optimization; systems theory; mathematics; scheduling; mixed integer linear programming; multi-skilled; Optimering; systemteori; matematik; schemaläggning; mixad linjär heltalsoptimering; multikompetent;

    Sammanfattning : This master thesis in optimization and systems theory is a development of two different optimization models formulated to schedule multi-skilled agents for contact centers depending on the forecasted demand, assigned by Teleopti. Four mixed integer linear programming models are created with the optimization programming language GAMS and solved by the internet based solver NEOS. LÄS MER

  4. 3. Multi-Objective Mixed-Integer Linear Optimisation of Aircraft Load Planning

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Kristján Óttar Rögnvaldsson; [2019]
    Nyckelord :;

    Sammanfattning : A general multi-objective optimisation model is developed for the load planning decision process of a bulk loaded commercial aircraft, using the Airbus A321 fitted with additional fuel tanks as a baseline platform. The model’s input is a specific set of load items, with associated quantities, mass and volume. LÄS MER
