  1. 1. Contributions to the Use of Statistical Methods for Improving Continuous Production

    Author : Francesca Capaci; Erik Vanhatalo; Bergquist Bjarne; Murat Kulahci; Johan Carlson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Process industry; Continuous process; Statistical process control; Design of experiments; Process improvements; Simulation tool; Engineering process control; Kvalitetsteknik; Quality Technology and Management;

    Abstract : Complexity of production processes, high computing capabilities, and massive datasets characterize today’s manufacturing environments, such as those of continuous andbatch production industries. Continuous production has spread gradually acrossdifferent industries, covering a significant part of today’s production. READ MORE

  2. 2. Algorithmically Guided Information Visualization : Explorative Approaches for High Dimensional, Mixed and Categorical Data

    Abstract : Software architecture has been identified as an increasingly important part of software development. The software architecture helps the developer of a software system to define the internal structure of the system. READ MORE

  4. 4. Obtaining Accurate and Comprehensible Data Mining Models : An Evolutionary Approach

    Author : Ulf Johansson; Lars Niklasson; Tom Ziemke; Thorsteinn Rögnvaldsson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Rule extraction; Ensembles; Data mining; Genetic programming; Artificial neural networks; Computer science; Datalogi; rule extraction; ensembles; data mining; genetic programming; artificial neural networks;

    Abstract : When performing predictive data mining, the use of ensembles is claimed to virtually guarantee increased accuracy compared to the use of single models. Unfortunately, the problem of how to maximize ensemble accuracy is far from solved. READ MORE

  5. 5. Quality management : National or global driving factors

    Author : Dag Kroslid; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Quality Management; Quality Development; Business Excellence; Total Quality Management; Culture; Hofstede;

    Abstract : Around the world Quality Management is commonly regarded by industrialists and academics as a management concept that encompasses the potential in any organisation of developing into a company-wide philosophy with a profound focus on stakeholder values and improvement processes. However, there are mounting evidence that Quality Management has developed into an important strategic issue also on a national level, and that some leading industrial nations have enjoyed significant gains in the post War era by means of nation-wide progresses in Quality Management.
