  1. 1. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

    University essay from Uppsala universitet/Datalogi

    Author : Olle Delborg; Elias Insulander; [2023]
    Keywords : route planning; route optimization; contraction hierarchies; mixed integer programming; vehicle routing problem; electric trucks; electric vehicles; battery; openstreetmap; shortest path; Dijkstra;

    Abstract : This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming.

  3. 2. A case study of disjunctive programming: Determining optimal motion trajectories for a vehicle by mixed-integer optimization

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oskar Jagstedt; Elias Vitell; [2023]
    Keywords : Optimization; disjunctive programming; integer programming; Gurobi; big-M; nonlinear programming;

    Abstract : This report considers an application of mixed-integer disjunctive programming (MIDP)where a theoretical robot can jump from one point to another and where the number ofjumps is to be minimized. The robot is only able to jump to the north, south, east andwest. READ MORE

  4. 3. Assessment of hydrogen supply chain for transport sector of Sweden

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

    Author : José Maria Soares Rodrigues; [2023]
    Keywords : Hydrogen; Hydrogen Supply Chain; Elecrolysis; 2030; Sweden; Electricity prices; MILP; Optimization; Vätgas; Vätgassupplykedja; Elektrolys; 2030; Sverige; Elpriser; MILP; Optimering;

    Abstract : Fuel cell electric vehicles, powered by hydrogen are an enticing alternative to fossil-fuel vehicles in order to reduce greenhouse gas emissions and consequently accomplish the environmental targets set to tackle the environmental crisis. It is crucial to develop the appropriate infrastructure if the FCEVs are to be successfully accepted as an alternative to fossil-fuel vehicles. READ MORE

  5. 4. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Erik Lundell; Gustav Molin; [2023]
    Keywords : Technology and Engineering;

    Abstract : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. READ MORE

  6. 5. 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
