  2. 1. Metamodel based multi-objective optimization

    Author : Kaveh Amouzgar; Peter Hansbo; Niclas Strömberg; Kent Salomonsson; Sunith Bandaru; Jönköping University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-objective optimization; strength Pareto evolutionary algorithm; SPEA2; metamodel; surrogate model; response surface; radial basis functions; RBF;

    Abstract : As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. READ MORE

  4. 2. Learning from Multi-Objective Optimization of Production Systems : A method for analyzing solution sets from multi-objective optimization

    Author : Catarina Dudas; Henrik Boström; Amos H.C. Ng; Johan Ölvander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Data mining; Post-optimization analysis; Production system analysis; data- och systemvetenskap; Computer and Systems Sciences;

    Abstract : The process of multi-objective optimization involves finding optimal solutions to several objective functions. However, these are typically in conflict with each other in many real-world problems, such as production system design. READ MORE

  5. 3. Optimization of radiation therapy planning using physical and biological objective functions

    Author : Patric Källman; Stockholms universitet; []
    Keywords : Radiation Physics; radiofysik;

    Abstract : The aim of radiation therapy is to eradicate all clonogenic tumour cells without causing severeinjury in normal tissues. Optimization of treatment planning means finding the most preferabletreatment prescription. During the recent years new methods for optimization that aim at solving theinverse problem in radiation therapy have been developed. READ MORE

  6. 4. Mathematical Multi-Objective Optimization of the Tactical Allocation of Machining Resources in Functional Workshops

    Author : Sunney Fotedar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Decision-making; Robust efficient solutions; Discrete bi-objective optimization; Capacity planning; Discrete tri-objective optimization; Production planning; Coverage gap;

    Abstract : In the aerospace industry, efficient management of machining capacity is crucial to meet the required service levels to customers and to maintain control of the tied-up working capital. We introduce new multi-item , multi-level capacitated resource allocation models with a medium--to--long--term planning horizon. READ MORE

  7. 5. Schizophrenia, social functions and quality of life

    Author : Lise-Lotte Nilsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; klinisk psykologi; Psykiatri; psykosomatik; Psychiatry; clinical psychology; psychosomatics;

    Abstract : A good quality of life (QoL) can be regarded as the ultimate goal of psychiatric treatment and rehabilitation. The objective of the present thesis was to study the how the QoL of patients with schizophrenia was related to their social functions and varying social environments. READ MORE
