  1. 1. Developing decision-support tools for evaluation of manufacturing reshoring decisions

    Författare :Movin Sequeira; Per Hilletofth; David Eriksson; Rudrajeet Pal; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing reshoring; decision-making; support tools; fuzzy logic; AHP; Produktion; reshoring; beslutsstödverktyg; fuzzy logik; AHP;

    Sammanfattning : During last three decades, companies have offshored their manufacturing activities across international borders in order to pursue lower manufacturing costs. Despite having accomplished their purpose, companies have also suffered from issues, especially poor quality of products and a poor response to customer demand. LÄS MER

  3. 2. Fuzzy Set Theory Applied to Make Medical Prognoses for Cancer Patients

    Författare :Hang Zettervall; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fuzzy set theory; the Mamdani fuzzy control system; the Sugeno controller; fuzzy c-means clustering analysis; point set approximation; linguistic models; the 2-tuple linguistic representations; the hesitant fuzzy linguistic term sets;

    Sammanfattning : As we all know the classical set theory has a deep-rooted influence in the traditional mathematics. According to the two-valued logic, an element can belong to a set or cannot. In the former case, the element’s membership degree will be assigned to one, whereas in the latter case it takes the zero value. LÄS MER

  4. 3. Dephosphorization of magnetite fines : surface reactions, flotation kinetics and fuzzy logic application

    Författare :Fenwei Su; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The primary objective of the research work presented in this thesis is to investigate the influence of chemical and operational variables on the apatite flotation kinetics and to establish a suitable model using traditional method and fuzzy logic. The thesis consists of three parts, i.e. LÄS MER

  5. 4. Modeling and improving Spatial Data Infrastructure (SDI)

    Författare :Ehsan Abdolmajidi; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial Data Infrastructure; System Dynamics; Fuzzy Logic; Data integration; Pattern detection; Resource Description Framework RDF ; Ontology;

    Sammanfattning : Spatial Data Infrastructure (SDI) development is widely known to be a challenging process owing to its complex and dynamic nature. Although great effort has been made to conceptually explain the complexity and dynamics of SDIs, few studies thus far have actually modeled these complexities. LÄS MER

  7. 5. Preprocessing perceptrons

    Författare :Lena Kallin Westin; Patrik Eklund; Lothar Gierl; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Preprocessing perceptron; Production line; Neural networks; Backpropagation; Fuzzy logic; ROC and QROC curves; Multivariate decision limits; Datalogi; Computer science; Datalogi; business data processing; administrativ databehandling;

    Sammanfattning : Reliable results are crucial when working with medical decision support systems. A decision support system should be reliable but also be interpretable, i.e. able to show how it has inferred its conclusions. LÄS MER
