  1. 1. Evaluating and Improving the Transport Efficiency of Logistics Operations

    Författare :Jiali Fu; Harilaos Koutsopoulos; Constantinos Antoniou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport efficiency; earthmoving operations; off-peak urban deliveries; simulation; optimization; GPS data; Transportvetenskap; Transport Science;

    Sammanfattning : The thesis focuses on evaluating and improving the transport efficiency of two types of logistics operations in the supply chain.One research area is the production of raw material in construction operations, specifically earthmoving operations. LÄS MER

  3. 2. Waste in road transport operations - using information sharing to increase efficiency

    Författare :Henrik Sternberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road transport operations; transport efficiency; ICT; information sharing; transport information systems; freight transportation; motor carrier;

    Sammanfattning : In terms of efficiency, road transport operations have historically seen very little development relative to other supply chain areas and some authors have even referred to freight transportation as the “forgotten factor.” Several studies world-wide have shown a generally low level of efficiency in road transport operations. The U.S. LÄS MER

  4. 3. The operating cycle representation of road transport missions

    Författare :Luigi Romano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; transport application; road mission; probability distributions; stochastic processes; energy estimation;

    Sammanfattning : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon.

  5. 4. Driverless trucks in the Swedish freight transport system : An analysis of future impacts on the transport system and the emerging innovation system

    Författare :Albin Engholm; Anna Pernestål; Ida Kristoffersson; Maria Oscott; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driverless Trucks; Automated Driving; Total Cost of Ownership; Freight Transport Modeling; Innovation Systems; Machine Design; Maskinkonstruktion;

    Sammanfattning : A large-scale introduction of driverless trucks could start taking place during the next decade. While this could bring several economic benefits for freight transport actors and society, it may also change the freight transport system and exacerbate the negative effects of road transport.

  7. 5. Operating cycle representations for road vehicles

    Författare :Pär Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

    Sammanfattning : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. LÄS MER
