  2. 1. Multi-Agent-Based Simulation and Optimization of Production and Transportation

    Author : Johan Holmgren; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis addresses the integration of software agent technology, simulation and mathematical optimization within the domain of production and transportation. It has been argued that agentbased approaches and mathematical optimization can complement each other in the studied domain. READ MORE

  4. 2. On the integration of optimization and agent technology for transportation and production planning

    Author : Johan Holmgren; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns the integration of agent technology and mathematical optimization for improved decision support within the domain of analysis and planning of production and transportation. These two approaches have often been used separately in this domain but the research concerning how to combine them is very limited. READ MORE

  5. 3. Studies in Local Public Transport Demand

    Author : Johan Holmgren; Jan Owen Jansson; Lars Westin; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Demand; Elasticity; Price; Service; Time series; Panel data; Kollektivtrafik; Efterfrågan; Elasticitet; Pris; Trafikutbud; Inkomst; Bilinnehav; Tidsserieanalys; Paneldata; Economics; Nationalekonomi;

    Abstract : This thesis consists of four papers where the overall purpose is to contribute to the understanding of how local public transport demand is affected by different factors. An underlying theme running trough the thesis is the two-way relationship between public transport demand and the service level caused by the fact that capacity and quality are joint products.

  6. 4. Route attribution of chemical warfare agents : Retrospective classification of unknown threat samples

    Author : Karin Höjer Holmgren; Johan Dahlén; Crister Åstot; Peter Haglund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Impurity profiling; Chemical attribution signature; Route sourcing;

    Abstract : Although chemical warfare agents (CWAs) are prohibited under international law, there have been numerous crimes that violates the 1997 Chemical Weapons Convention (CWC) during the last decade, especially in the civil war in Syria where sarin, mustard gas and chlorine have all been used. CWAs have also been used in political assassinations and attempts thereof. READ MORE

  7. 5. On the Use of Simulation and Optimization for the Analysis and Planning of Prehospital Stroke Care

    Author : Saeid Amouzad Mahdiraji; Johan Holmgren; Radu-Casian Mihailescu; Jesper Petersson; Tobias Andersson Granberg; Malmö universitet; []
    Keywords : Stroke Transport Policies; EMS; Mobile Stroke Unit; MSU; Simulation; Optimization; Modeling Framework.;

    Abstract : Immediate treatment is of extreme importance for stroke patients. However, providing fast enough treatment for stroke patients is far from trivial, mainly due to logistical challenges and difficulties in diagnosing the correct stroke type. READ MORE
