  1. 1. Simulated annealing for Vehicular Ad-hoc Networks

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :ETHISH VENUMBAKKA; [2023]
    Nyckelord :Simulated Annealing; Vehicle Ad Hoc Networks;

    Sammanfattning : In this thesis, we tackle a significant optimization challenge within Vehicular Ad Hoc Networks (VANETs) by employing a simulated annealing approach. We focus on developing an efficient Vehicle Routing Problem (VRP) algorithm to sift through numerous potential solutions and identify the best one. LÄS MER

  3. 2. 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

  4. 3. A literature study on factors influencing the planning of green routes for heavy trucks

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :Berk Özkan; Anders Nyberg; [2021]
    Nyckelord :Heavy truck; green route; fuel consumption; HDV;

    Sammanfattning : The efficiency of the transport sector is under close examination due to multiple different reasons. Among them are the environmental aspects of emission reduction along with the need to maintain a tight time schedule. Heavy trucks have a significant negative impact on the environment and are sensitive to external factors. LÄS MER

  5. 4. WSN Routing Schedule Based on Energy-aware Adaptation

    Master-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Tingqing Peng; [2020]
    Nyckelord :Multi-objective Optimization Problem; Routing schedule; KSP; Wireless sensor network;

    Sammanfattning : In view of the problem of uneven load distribution and energy consumption among nodes in a multi-hop wireless sensor network, this research constructs the routing schedule problem as a MOP (Multi-objective Optimization Problem), and proposed an energy-aware routing optimization scheme RDSEGA based on multi-objective optimization. In this scheme, in order to avoid the searching space explosion problem caused by the increase of nodes, KSP Yen's algorithm was applied to prune the searching space, and the candidate paths selected after pruning are recoded based on priority.

  7. 5. Winter Road Maintenance Planning-Decision Support Modelling

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Keegan Mbiyana; [2018]
    Nyckelord :Decision Support System; Winter Road Maintenance; Optimal maintenance Cost; Sensitivity analysis; Road condition; Maintenance framework; Digital representation; Operations research.;

    Sammanfattning : Winter in Northern Sweden comes with very harsh and unpredictable condition associated with large amounts of snowfall covering roadways thereby affecting transportation by roads. When the road conditions i.e. LÄS MER
