  1. 1. Alternative logistic routes and their aggregate effect on the use of infrastructure : the potential of using multiple routes in the Samgods model

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Anton Åkerström; Sebastian Morel; [2023]
    Nyckelord :Samgods; Discrete Choice Models;

    Sammanfattning : The primary objective of this thesis is to assess the different statistical methods used forcalibrating the Samgods model, which is a transportation planning tool employed in Sweden toforecast the demand for freight transport. By focusing on the specific context of national logisticsmodels, this research aims to enhance the accuracy and reliability of the Samgods model throughproposed improvements. LÄS MER

  3. 2. Godstransporter : Utveckling, mätning och samband

    Kandidat-uppsats, Umeå universitet/Kulturgeografi

    Författare :Finn Bindler; [2023]
    Nyckelord :;

    Sammanfattning : Abstract  Sweden is an import and export dependent country and the main means of transportation of freight is by road transportation. Road transportation includes light to heavy trucks and are used for all types of purposes, for example from warehouse to market or from storage to building site. LÄS MER

  4. 3. Analysis of a mathematical model in Python for geographical disaggregation of freight growth rates based on the pivot-point method

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Karl Hernebrant; [2019]
    Nyckelord :;

    Sammanfattning : One of the tasks for the Swedish Transport Agency, Trafikverket, is to provide traffic forecasts. To do this, a number of different forecast models are used, where Samgods is a nationally estimated model, where the quality of the results gets more unstable the more disaggregated level you are looking at.

  5. 4. Development of the frequency optimization model for the national freight flows in Samgods

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Erica Hellberg; David Nilsson; [2018]
    Nyckelord :Nyckelord: Samgods; Frekvensoptimering; Konsolidering; Logistik;

    Sammanfattning : I verktyget Samgods utförs totalkostnadsberäkningar om hur många gånger per år som transporterna av gods ska utföras, det vill säga med vilken frekvens. I den nuvarande frekvensoptimeringsmetoden i Samgods optimeras inte dessa frekvenser, vilket främst beror på att optimeringsproblemets kostnadsfunktioner är icke-konvexa. LÄS MER

  7. 5. A discrete choice model of transport chain and shipment size on Swedish commodity flow survey 2004/2005

    Master-uppsats, KTH/Trafik och logistik

    Författare :Shiva Habibi; [2010]
    Nyckelord :Disaggregate freight transport demand; transport chain and shipment size choice;

    Sammanfattning : Freight demand models have not been developed that much as passenger demand models. The reason is existence of too many complexities in this area. To estimate a disaggregate freight transport models large input data is required. LÄS MER
