  1. 1. Optimal Truck Scheduling Mathematical Modeling and Solution by the Column Generation Principle

    University dissertation from Matematiska institutionen

    Author : Myrna Palmgren; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

    Abstract : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. READ MORE

    Abstract : This thesis, which consists of an introduction and five appended papers, concerns the optimal selection of tyres for a variety of vehicle configurations as well as operating environments. The selection problem stems from a project cooperation between Chalmers University of Technology and Volvo Group Trucks Technology. READ MORE

  4. 4. On truck tyre modelling

    University dissertation from Institutionen för farkostteknik

    Author : Boris Thorvald; KTH.; [1998]
    Keywords : ;

    Abstract : A physically based 3D tyre model with transient propertiesand reasonable computational effort is presented. Basic dynamitbehaviour is considered with the tyre belt modelled as a rigidring. READ MORE

  5. 5. Methods to quantify and qualify truck driver performance

    University dissertation from Halmstad : Halmstad University Press

    Author : Iulian Carpatorea; Högskolan i Halmstad.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Driver performance; heavy-duty vehicle; fuel economy; fuel consumption; fuel prediction; truck driver;

    Abstract : Fuel consumption is a major economical component of vehicles, particularly for heavy-duty vehicles. It is dependent on many factors, such as driver and environment, and control over some factors is present, e.g. route, and we can try to optimize others, e. READ MORE
