2. 16. 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

4. 17. Transportation Mission Based Optimization of Heavy Vehicle Fleets including Propulsion Tailoring

   Author : Toheed Ghandriz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; heterogeneous heavy vehicle fleet; optimal energy management; propulsion system tailoring; Automated Driving Systems; electrified propulsion; total cost of ownership; electromobility; transportation mission; fleet sizing;

   Abstract : Over decades freight vehicles were produced for a wide range of operational domains so that vehicle-manufacturers were not concerned much about the actual use-cases of the vehicles. Environmental issues, costumer expectations along with growing demand on freight transport created a competitive environment in providing better transportation solutions. READ MORE

5. 18. Visual response to attentional demand in increasing levels of automation: A situated approach

   Author : Alberto Morando; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-world driving; naturalistic data; human factors; automation; visual behavior; driving demand; Attention;

   Abstract : Introduction: Adaptive cruise control (ACC) is a system that automates the longitudinal control of the vehicle, and maintains safety margins to a lead vehicle. ACC has been shown to have positive safety effects in reducing the exposure to critical situations. READ MORE

6. 19. Environmental Impacts of Shared Mobility: Potential, Factors, and Assessments

   Author : Ana Maria Arbelaez Velez; Internationella miljöinstitutet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shared mobility; Environmental impact; sustainable transportation; input and output analysis; Life Cycle Assessment LCA; demand-side solutions;

   Abstract : Environmental impacts from passenger transportation continue to increase globally due to a rise in kilometers traveled and a shift to emission-intensive transportation modes (from public transportation and active modes such as walking and cycling to motorcycle and car ridership). The electrification of the passenger fleet, coupled with low-carbon energy sources, is expected to decrease some of the environmental impacts associated with passenger transportation, including local air pollution, greenhouse gas emissions and fuel depletion.

7. 20. Communication technology and travel demand models

   Author : Maria Börjesson; Infrastruktur KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travel survey; Transport mode; Telecommuting; Mathematical model; Motivation; 11 Road: Personal transport; 11 Road: Personal transport;

   Abstract : Transportation planners have traditionally focused on physical travel only, and disregarded the fact that other modes of communication may influence travel demand. However, modern telecommunications are rapidly increasing the accessibility to activities that previously only could be reached by physical transportation. READ MORE
