  1. 1. Exploring Software Cost Estimation Inaccuracy

    Författare :Ana Magazinius; [2012]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational politics; estimation inhibitors; project management; software cost and effort estimation; learning in organizations; informal use of estimates;

    Sammanfattning : The inaccuracy of software cost estimates has for long been a source of frustration to software practitioners and cost estimation researchers. Despite huge efforts to improve this important practice, estimation accuracy is still low. This thesis uses empirical and theoretical evidence to investigate why this problem persists. LÄS MER

  2. 2. Cost Optimization of Aircraft Structures

    Detta är en avhandling från Stockholm : KTH

    Författare :Markus Kaufmann; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER

  3. 3. Automated Cost Estimation of Product Variants : A Tool for Enhanced Producibility

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Fredrik Elgh; Högskolan i Jönköping.; Högskolan i Jönköping.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost Estimation; Design for Producibility; Design Automation; Variant Design; Process Planning; Producibility Evaluation; System Development; Information Modelling;

    Sammanfattning : The estimation of product cost is a central activity in the design process. Most companies act in an environment of high competition where the market sets the product price. This, in combination with a focus on satisfying the shareholders’ demand for return on investment, results in a focus on cost as a constraint. LÄS MER

  4. 4. On Parameter Estimation Applications in Radio Astronomy and Power Networks

    Detta är en avhandling från Karlskrona : Blekinge Tekniska Högskola

    Författare :Jonas Lundbäck; Blekinge Tekniska Högskola.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; Antenna arrays; FMCW-radar; Polarization estimation; Fault locator;

    Sammanfattning : Signal processing is a common part of the modern society used to obtain high functionality in a vast number of applications. As the development of advanced electronics and powerful computers continue, the limit of the functionality in many systems is increased. LÄS MER
