  2. 2. Envisioning a Future Decision Support System for Requirements Engineering A Holistic and Human-centred Perspective

    University dissertation from Institutionen för datavetenskap

    Author : Beatrice Alenljung; Anne Persson; Sture Hägglund; Pär Carlshamre; Per Ågerfalk; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Requirements engineering; decision-making; decision support systems; RE decision-making; RE decision support; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Informatics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informatik;

    Abstract : Complex decision-making is a prominent aspect of requirements engineering (RE) and the need for improved decision support for RE decision-makers has been identified by a number of authors in the research literature. The fundamental viewpoint that permeates this thesis is that RE decision-making can be substantially improved by RE decision support systems (REDSS) based on the actual needs of RE decision-makers as well as the actual generic human decision-making activities that take place in the RE decision processes.

  3. 3. Identifying critical components for system reliability in power transmission systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transmission system reliability; component reliability importance index; Great Britain power system; power flow analysis; system adequacy; system security; system vulnerability;

    Abstract : Large interruptions of power supply in the transmission system have considerable impact on modern society. The goal for the transmission system operator (TSO) is to prevent and mitigate such events with optimal decisions in design, planning, operation and maintenance. READ MORE

  4. 4. A data-driven decision support system for coherency of experts’ judgment in complex classification problems The case of food security as a UN sustainable development goal

    University dissertation from Borlänge : Dalarna University

    Author : Rueben Laryea; Kenneth Carling; Lena Nerhagen; [2018]

    Abstract : Everyday humans need to make individual or collective decisions. Often the decisions aim at achieving multiple goals (thus involving multiple criteria) and rely on the decision maker(s)’ intuition, internal data, as well as external sources of data. READ MORE

  5. 5. Predictive Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution

    University dissertation from Luleå University of Technology

    Author : Mike Gerdes; Diego Galar; Uday Kumar; Dieter Scholz; Piotr Bilski; [2019]
