  1. 1. Cost Optimization of Aircraft Structures

    Författare :Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; 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

  2. 2. Activity-Based Costing : avbildning, integration & nytta

    Författare :Henrik Nehler; Lars A. Samuelson; Linköpings universitet; []
    Nyckelord :Activity-Based Costing; Activity-Based Management; activities; cost pools; cost drivers; product costing; cost accounting; management accounting; management control systems; cost system complexity sophistication; degree of integration; information value; Activity-Based Costing; ekonomistyrning; kostnader; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : This doctoral dissertation provides an extensive analysis of Activity-Based Costing, one of the most discussed management accounting models during the 90's. The aim of the study is to analyse the prerequisites for the design, integration and use of Activity-Based Costing systems. LÄS MER

  3. 3. Information Management for Cutting Tools : Information Models and Ontologies

    Författare :Olof Nyqvist; Torsten Kjellberg; Fumihiko Kimura; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Production Engineering; Cutting Tools; Information Models; International Standards; Reference Data; Ontologies; Information technology; Informationsteknologi;

    Sammanfattning : There is an increasing demand for the exchange of important product and manufacturing information in a computer interpretable way. Large manufacturing companies are dependent on having access to the necessary information electronically. LÄS MER

  4. 4. Methods and Models for Cutting Data Optimization

    Författare :Sören Hägglund; Chalmers University of Technology; []
    Nyckelord :Tool Life; Cutting Forces; Tool Replacement Coordination; Process Cost; Tooling Cost; Cutting Data Optimization; Surface Finish; Cycle Time Balancing;

    Sammanfattning : Traditional optimization of cutting processes refers to minimizing cost or minimizing time (minimumcost or maximum production rate). These criteria apply to the cutting speed via well-known equationsfor economic tool life and tool life for maximum production rate. Quite often speed is focused firstwhen after some suitable feed value is chosen. LÄS MER

  5. 5. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

    Författare :Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. LÄS MER
