  1. 6. Lean Remanufacturing : Reducing Process Lead Time

    Författare :Jelena Kurilova-Palisaitiene; Erik Sundin; Bozena Poksińska; Mats Björkman; Martin Kurdve; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Lean Production; Toyota Production System; Value Stream Mapping; Remanufacturing Process Challenges and Improvements; Process Efficiency;

    Sammanfattning : Remanufacturing is a product recovery option in which used products are brought back into useful life. While the remanufacturing industry stretches from heavy machinery to automotive parts, furniture, and IT sectors, it faces challenges. LÄS MER

  3. 7. Process development for combined pentose and hexose fermentation

    Författare :Fredrik Nielsen; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Lignocellulose; Xylose fermentation; Co-fermentation; Process design; Agricultural residues; Saccharomyces cerevisiae;

    Sammanfattning : Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved.

  4. 8. Methods for improving performance of process planning for CNC machining : an approach based on surveys and analytical models

    Författare :Staffan Anderberg; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CNC machining; metal cutting; performance; process capability; environment; energy; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Process planning as an enabler of competiveness is often overlooked, but being one of the principal function in the product realisation flow it holds a key role by combining both product and production requirements into a production concept with respect to the current manufacturing system. As such the capability of process planning to a large extent dictates production cost, lead times, product quality etc. LÄS MER

  5. 9. Improving Business Processes using Process-oriented Data Warehouse

    Författare :Muhammad Khurram Shahzad; Paul Johannesson; Jelena Zdravkovic; Marite Kirikova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process analysis; business process improvement; goal-driven process improvement. process-oriented data warehouse; business-orientation of process warehouse; decision making; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : The Business Process Management (BPM) lifecycle consists of four phases: design and analysis, configuration, enactment, and evaluation - also known as performance analysis and improvement. Performance analysis and improvement of business processes, one of the core phases in the BPM life cycle, is becoming on top of the agenda for many enterprises. LÄS MER

  7. 10. The wet fermentation biogas process : Limitations and possibilities for efficiency improvements

    Författare :Johan Lindmark; Rebei Bel Fdhila; Bo Svensson; Mälardalens högskola; []
    Nyckelord :Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The biogas process is known as an environmental friendly and sustainable way of producing energy and fuel but to be fully commercially competitive with other types of processes, efficiency improvements are needed. By doing a case study at the Växtkraft biogas plant in Västerås, Sweden, three specific limitations were identified and studied. LÄS MER
