  1. 1. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    Författare :Dimitar Nikolov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Sammanfattning : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. LÄS MER

  3. 2. Materials Supply and Product Descriptions for Assembly Systems - Design and Operation

    Författare :Lars Medbo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; long cycle time work; product structure; manual assembly; parallel product flow; assembly systems design; materials kit;

    Sammanfattning : This thesis discusses and reports on assembly systems design, concerning manual assembly of complex products involving production with requirement for flexibility in production volumes and product variants. The research is based on more than a decade of work within the Swedish automotive industry focusing on parallel product flows and long cycle time assembly work. LÄS MER

  4. 3. Use of FE-analysis for predicting and verifying the design of an automotive component forming process with special regard to macro geometric defects

    Författare :Alf Andersson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; information exchange; sheet-metal forminA simulation finite element analysis; springback surface defects Classflcation system and or Index term If any ;

    Sammanfattning : This thesis includes four appended papers. The thesis describes the challenges and advantages of the use of FE-analysis in the design of a component forming process in the automotive industry. LÄS MER

  5. 4. Automated Verification and Generation of Flexible Automation Control

    Författare :Johan Richardsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; manufacturing systems; program generation; control; verification;

    Sammanfattning : Consumer product life-cycles are constantly shortening; the automotive industry is an illustrative example. As a consequence, the introduction of new products into the manufacturing system necessarily becomes more frequent. Inherently, this brings a performance reduction for the manufacturing system.

  7. 5. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases

    Författare :Ola S Wagersten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perceived Quality; variation simulation; visualization and evaluation; Geometrical variation; geometry assurance; non-rigid; tolerance analysis; product development;

    Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
