  2. 1. Reflections on Process-based Supply Chain Modelling and Analysis

    Author : Robert Lindroth; Teknisk logistik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process mapping; supply chain management; modelling; simulation.;

    Abstract : The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT.

  4. 2. Intermodal Road-Rail Transportation for Express Transport Services

    Author : Sofia Ohnell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport services; Intermodal transportation; transport systems; modelling; express transportation;

    Abstract : Express transport services are produced in highly modularised transport systems, a fact that implies that one subsystem can be exchanged for another without causing a need for major changes in other parts of the system. Express goods are not common on a large scale in freight railway transport systems, as those are often not considered reliable enough for time-critical goods. READ MORE

  5. 3. Evaluation and Modelling of Short Haul Intermodal Transport Systems

    Author : Behzad Kordnejad; Sebastian Stichel; Bo-Lennart Nelldal; Sebastiaan Meijer; Johan Woxenius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Abstract : Conventional intermodal rail freight transport systems have proved themselves competitive and able to offer cost-leadership on long distances and in endpoint relations between two nodes. Several studies within intermodal transports have made contributions in finding the minimum distance, the “break-even” distance that an intermodal door-to-door shipment can compete with unimodal road.

  6. 4. Supply chain optimization in the forest industry

    Author : Helene Gunnarsson Lidestam; Mikael Rönnqvist; Jan Lundgren; Eldon Gunn; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supply chain; logistics; forestry; optimization; modelling; transportation; mixed integer programming models; försörjningskedjor; logistik; optimering; modellering; transportplanering; blandade heltalsproblem; skogsindustrin; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : The scope of this thesis is modelling and solving large-scale planning problems in the supply chain within the forest industry. Five research papers are included, the first three of which focus on the modelling, and the last two on the solution methods. READ MORE

  7. 5. Development of Small-Scale Intermodal Freight Transportation in a Systems Context

    Author : Johan Woxenius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport chain; conceptual modelling; barrier; transshipment technology; transportation system; intermodal freight transportation; gateway terminal; combined transport; yransport network; technology implementation;

    Abstract : An intermodal freight transportation system is characterised by the subsequent use of different transportation modes for moving goods stowed into unit loads from the consignor to the consignee. Typically, it involves a wide variety of activities, actors and resources, which implies a certain degree of technological as well as organisational complexity. READ MORE
