  1. 1. Automatic Instance-based Tailoring of Parameter Settings for Metaheuristics

    Author : Felix Dobslaw; Theo Kanter; Åke Malmberg; Thomas Bartz-Beielstein; Mittuniversitetet; []
    Keywords : Algorithm Configuration; Parameter Tuning; Parameter Control; Metaheuristics;

    Abstract : Many industrial problems in various fields, such as logistics, process management, orproduct design, can be formalized and expressed as optimization problems in order tomake them solvable by optimization algorithms. However, solvers that guarantee thefinding of optimal solutions (complete) can in practice be unacceptably slow. READ MORE

  2. 2. Parameter Estimation of a DOC from Engine Rig Experiments

    Author : Björn Lundberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Data Analysis; Parameter Estimation; Exhaust Aftertreatment Modeling; Design of Experiments; Engine Test Bench; DOC; Full Scale;

    Abstract : In this thesis methods of parameter estimation of a Diesel Oxidation Catalyst (DOC) from engine rig experiments were investigated. The investigation did not only include methods of parameter fitting to experimental data but a large effort was also put into catalyst modeling and experimental design. READ MORE

  3. 3. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Author : Björn Lundberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Abstract : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. READ MORE

  4. 4. A Simulation-Based Optimisation Method for PLC Systems

    Author : Bo Svensson; Bengt Lennartson; Rolf Bernhardt; Högskolan Väst; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE
