  1. 16. Software Investments under Uncertainty : Modeling Intangible Consequences as a Stochastic Process

    Författare :Emil Numminen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software investment valuation; usage; intangible consequences; cash flow; discounted cash flow model; stochastic process;

    Sammanfattning : Software systems are today a part of more or less every organization. The varieties of software used in organizations are ranging from simple log-keeping applications to advanced decision support systems. The task of a priori valuation of software investments has attracted a lot of research for a long time. LÄS MER

  3. 17. Water and Carbon Balance Modeling: Methods of Uncertainty Analysis

    Författare :John Juston; Per-Erik Jansson; Georg Lindgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; uncertainty analysis; water balance; carbon balance; GLUE; Environmental engineering; Miljöteknik;

    Sammanfattning : How do additional data of the same and/or different type contribute to reducing model parameter and predictive uncertainties? This was the question addressed with two models – the HBV hydrological water balance model and the ICBM soil carbon balance model – that were used to investigate the usefulness of the Generalized Likelihood Uncertainty Estimation (GLUE) method for calibrations and uncertainty analyses.  The GLUE method is based on threshold screening of Monte Carlo simulations using so-called informal likelihood measures and subjective acceptance criterion.

  4. 18. Supplier Involvement in New Product Development under Technological Uncertainty

    Författare :Lisa Melander; Fredrik Tell; Thomas Johnsen; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; New product development; supplier involvement; collaborative R D; technological uncertainty; supplier selection; buyer-supplier collaboration; coordination; R D; purchasing; project;

    Sammanfattning : This thesis addresses the challenges that firms are faced with when collaborating with suppliers in new product development (NPD) projects under technological uncertainty. A critical observation that is made in this context is that technologies are evolving faster, making products more complex. At the same time, firms become more specialized. LÄS MER

  5. 19. Exploring the bits and pieces of curiosity : an information-theoretic approach to understanding what compels information-seeking

    Författare :Gustaf Wadenholt; Linus Holm; Paul Schrater; Ronald van den Berg; Kou Murayama; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Curiosity; uncertainty; information seeking; information gaps; learning satisfaction; learning reward; extrinsic reward; distraction; Psychology; psykologi;

    Sammanfattning : The aim of this thesis is to investigate the computational mechanisms that drive curiosity, the motivational state for learning for its own sake. Curiosity is operationalized as information-seeking behaviors and self-reported curiosity. LÄS MER

  7. 20. Situation analysis for fighter aircraft combat survivability

    Författare :Tina Erlandsson; Lars Niklasson; Göran Falkman; Silvia Coradeschi; Per-Johan Nordlund; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fighter aircraft; situation analysis; combat survival; decision support; uncertainty; Datalogi; Computer and Systems Science; Teknik;

    Sammanfattning : Fighter pilots operate in environments where an erroneous decision may have fatal consequences. A tactical decision support system (TDSS) could aid the pilots to analyze the situation and make correct decisions. The TDSS can, for instance, highlight important information and suggest suitable actions. LÄS MER
