  1. 1. Capacity utilisation in short sea shipping

    Författare :Linda Styhre; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sailing schedule; unutilised capacity; improvement measures; Liner short sea shipping; vessel capacity utilisation; route characteristics; strategies;

    Sammanfattning : Shipping is a capital-intensive industry and is characterised by high fixed costs and economies of scale. Trade imbalances and demand variations, market fluctuations and customer demands for high frequency create a situation where shipping companies tend to operate with a high level of unutilised vessel capacity.

  3. 2. Railway capacity analysis : Methods for simulation and evaluation of timetables, delays and infrastructure

    Författare :Anders Lindfeldt; Bo-Lennart Nelldal; Ullrich Martin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Kapacitet; Järnvägsgruppen - Kapacitet;

    Sammanfattning : In this thesis the symptoms and underlying behaviour of congestion on railways are analysed and discussed. As well as in many other countries, Sweden faces increasing demand for transportation. To meet this new demand, railways play an important role. LÄS MER

  4. 3. Process Efficiency and Capacity Flexibility : Developing a Support Tool for Capacity Decisions in Manual Assembly Systems

    Författare :Per Petersson; Peter Holmstedt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Productivity is an important measure of competitiveness and one important factor influencing productivity is capacity utilisation. In order to achieve high productivity, there should be no more capacity in a system than is required by the current demand rate. LÄS MER

  5. 4. Energy efficiency improvements in logistics as a means to environmental sustainability: The case of capacity utilisation in road freight transportation

    Författare :Jessica Wehner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Capacity utilisation; household logistics capability; system levels; distribution structure; logistics system; energy efficiency; last-mile fulfilment; overcapacity; system boundaries; road freight transportation;

    Sammanfattning : The energy consumption in logistics, and especially in road freight transportation, is steadily increasing and with that the greenhouse gas emissions which have a negative impact on the environment. In order to improve environmental sustainability of logistics, a change in the actors’ behaviour and policies is needed since the development of technology alone is not sufficient. LÄS MER

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

    Författare :Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
