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

    University dissertation from Linköping : Linköpings universitet

    Author : Marcus Redhe; Linköpings universitet.; Linköpings universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  2. 2. Towards strategic development of maintenance and its effects on production performance A hybrid simulation-based optimization framework

    University dissertation from Skövde : University of Skövde

    Author : Gary Linnéusson; Högskolan i Skövde.; Högskolan i Skövde.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic development; maintenance behavior; maintenance management; sustainable change; tradeoff optimization; system dynamics; discrete event simulation; problem structuring; multi-objective optimization; decision support; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : Managing maintenance in manufacturing within an economical short-termism framework and taking the consequential long-term cost effects into account is hard. The increasing complexity of managing maintenance and its impact on the business results calls for more advanced methods to support long-term development through effective activities in the production system environment.

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Farzad Kamrani; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-based Optimization; UAV Path Planning; Business Process Optimization;

    Abstract : 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.

  4. 4. Dynamic Resampling for Preference-based Evolutionary Multi-objective Optimization of Stochastic Systems Improving the efficiency of time-constrained optimization

    University dissertation from Skövde : Högskolan i Skövde

    Author : Florian Siegmund; Högskolan i Skövde.; Högskolan i Skövde.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolutionary multi-objective optimization; simulation-based optimization; guided search; preference-based optimization; reference point; decision support; noise; stochastic systems; dynamic resampling; budget allocation; sequential sampling; hybrid; ranking and selection; Natural sciences; Naturvetenskap; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : In preference-based Evolutionary Multi-objective Optimization (EMO), the decision maker is looking for a diverse, but locally focused non-dominated front in a preferred area of the objective space, as close as possible to the true Pareto-front. Since solutions found outside the area of interest are considered less important or even irrelevant, the optimization can focus its efforts on the preferred area and find the solutions that the decision maker is looking for more quickly, i.

  5. 5. Mathematical modelling for optimization of truck tyres selection

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Zuzana Sabartova; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; simulation-based optimization; truck tyres selection; surrogate model; radial basis function interpolation; rolling resistance coefficient; combinatorial set of problem instances; global optimization;

    Abstract : This thesis, which consists of an introduction and three appended papers, concerns the optimal selection of tyres for a given vehicle configuration and an operating environment in which the vehicle is to be used. The optimization problem stems from an industrial project performed in cooperation between Chalmers University of Technology and Volvo Group Trucks Technology (GTT). READ MORE
