  1. 1. Simulation based design : structural optimization at early design stages

    Författare :Marcus Redhe; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The aim of this thesis is to evaluate and develop different modelling tools which can be used in the vehicle crashworthiness design process. These tools will improve the understanding of the vehicle behaviour and thus improve the crashworthiness of the vehicle. LÄS MER

  3. 2. A Simulation-Based Optimisation Method for PLC Systems

    Författare :Bo Svensson; Bengt Lennartson; Rolf Bernhardt; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation based optimisation; Virtual manufacturing; Industrial control system; PLC; Continuous simulation; Parameter tuning; Optimisation methods; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Tuning of process parameters such as time constants, cam values, velocities and robot paths, in order to increase capacity utilisation, is today a challenging manual on-line task in many automated manufacturing systems. On-line methods interfere with production and will cause unwanted downtime, which indeed reduces capacity utilisation. LÄS MER

  4. 3. Simulation-based Optimization and Decision Making with Imperfect Information

    Författare :Farzad Kamrani; Rassul Ayani; Stephen John Turner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-based Optimization; UAV Path Planning; Business Process Optimization;

    Sammanfattning : The purpose of this work is to provide simulation-based support for making optimal (or near-optimal) decisions in situations where decision makers are faced with imperfect information. We develop several novel techniques and algorithms for simulation-based optimization and decision support and apply them to two categories of problems: (i) Unmanned Aerial Vehicle (UAV) path planning in search operations, and; (ii) optimization of business process models.

  5. 4. Simulation-Based Approaches in Financial Econometrics

    Författare :Pär Sjölander; Mohsen Bahmani-Oskooee; Jönköping University; []
    Nyckelord :Economics; Nationalekonomi;

    Sammanfattning : This doctoral thesis consists of four chapters all related to the field of financial econometrics. The main contributions are based on the empirical evaluation of theories in or related to financial economics supported by the recent advances of models and simulation-based methods in time-series econometrics.

  7. 5. A real-time simulation-based optimisation environment for industrial scheduling

    Författare :Marcus Frantzén; Philip Moore; David Stockton; Amos Ng; Stephen Newman; Riham Khalil; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling system; Simulation; Scheduling; simulation-based optimisation; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : In order to cope with the challenges in industry today, such as changes in product diversity and production volume, manufacturing companies are forced to react more flexibly and swiftly. Furthermore, in order for them to survive in an ever-changing market, they also need to be highly competitive by achieving near optimal efficiency in their operations. LÄS MER
