    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport efficiency; earthmoving operations; off-peak urban deliveries; simulation; optimization; GPS data; Transportvetenskap; Transport Science;

    Abstract : 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. READ MORE

  4. 2. Novel Algorithms for Optimal Transport via Splitting Methods

    Author : Jacob Lindbäck; Mikael Johansson; Jérôme Malick; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimal transport; splitting methods; Optimeringslära och systemteori; Optimization and Systems Theory;

    Abstract : This thesis studies how the Douglas–Rachford splitting technique can be leveraged for scalable computational optimal transport (OT). By carefully splitting the problem, we derive an algorithm with several advantages. READ MORE

  5. 3. On optimal mission planning for conventional and electric heavy duty vehicles

    Author : Ahad Hamednia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics planning; Transport efficiency; Mission planning; Optimal control; Eco-driving; Model predictive control;

    Abstract : Ever-growing energy consumption and CO2 emissions due to the increase in road transport are major challenges that attract international attention, especially policy makers, logistic service providers and customers considering environmental, ecological and economic issues. Other negative side-effects caused by the growth of the road transport are the extensive economic and social costs because of traffic congestion. READ MORE

  6. 4. Simulation Studies of Impact of Heavy-Duty Vehicle Platoons on Road Traffic and Fuel Consumption

    Author : Ingrid Johansson; Xiaoliang Ma; Wilco Burghout; Henrik Pettersson; Xiaobo Qu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; microscopic traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; Transportvetenskap; Transport Science;

    Abstract : The demand for road freight transport continues to grow with the growing economy, resulting in increased fossil fuel consumption and emissions. At the same time, the fossil fuel use needs to decrease substantially to counteract the ongoing global warming. READ MORE

  7. 5. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

    Author : Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; road traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; railway traffic simulation; microscopic simulation; macroscopic simulation; freight trains; early departures; capacity; railway stations; strategic planning; timetable compression; UIC Code 406; Transportsystem; Transport Systems;

    Abstract : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. READ MORE
