  1. 21. Sustainable supplier selection in the logistics industry

    Författare :Kamran Rashidi; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inköp; Benchmarking; Logistik miljöaspekter; Benchmarking Management ; Industrial procurement; Purchasing;

    Sammanfattning : Supplier selection has become one of the most crucial tasks in supply chain management, especially in the procurement function. In recent years, the importance of selecting the best possible suppliers has been enhanced due to the emergence of sustainability issues. LÄS MER

  3. 22. Evaluation of forecasting techniques and forecast errors : with focus on intermittent demand

    Författare :Peter Wallström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : To decide in advance the amount of resources that is required next week or next month can be both a complicated and hazardous task depending on the situation, despite the known time frame when the resources are needed. Intermittent demand, or slow-moving demand, that is when there are time periods without demand and then suddenly a time period with demand, becomes even more difficult to forecast. LÄS MER

  4. 23. Absorption non-uniformity characterisation and its impact on flexographic ink distribution of coated packaging boards

    Författare :Sofia Thorman; Li Yang; Göran Ström; Magnus Lestelius; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid absorption; Absorption non-uniformity; Characterisation; Measurement technique; Print Mottle; Flexography; Coated packaging boards; Chemical Engineering; Kemiteknik;

    Sammanfattning : There are high demands on flexographic print quality to be sufficiently high and consistent in order to create a competitive packaging. At the same time the production efficiency need to be high. Printers thus need to achieve the same quality every time and quickly start-up new printing jobs. LÄS MER

  5. 24. Automated Bottleneck Analysis of Production Systems : Increasing the applicability of simulation-based multi-objective optimization for bottleneck analysis within industry

    Författare :Jacob Bernedixen; Amos H. C. Ng; Anna Syberfeldt; Kalyanmoy Deb; Leif Pehrsson; Magnus Wiktorsson; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bottleneck analysis; bottleneck identification; bottleneck improvement; multi-objective optimization; simulation; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Manufacturing companies constantly need to explore new management strategies and new methods to increase the efficiency of their production systems and retain their competitiveness. It is of paramount importance to develop new bottleneck analysis methods that can identify the factors that impede the overall performance of their productionsystems so that the optimal improvement actions can be performed.

  7. 25. Identifying critical components for system reliability in power transmission systems

    Författare :Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transmission system reliability; component reliability importance index; Great Britain power system; power flow analysis; system adequacy; system security; system vulnerability;

    Sammanfattning : Large interruptions of power supply in the transmission system have considerable impact on modern society. The goal for the transmission system operator (TSO) is to prevent and mitigate such events with optimal decisions in design, planning, operation and maintenance. LÄS MER
