  1. 1. Dynamic Modelling and Analysis of Information Flows in Production-Inventory and Supply Chain Systems

    Författare :Joakim Wikner; Jönköping University; []
    Nyckelord :Industrial dynamics; Control theory; Production-inventory system; Supply chain; Net present value; MCDM;

    Sammanfattning : System dynamics is the fundamental concept of this academic dissertation. The focus is on analysis and modelling of properties representative for production-inventory and supply chain systems. The modelling approach is based on Industrial Dynamics but employs a hybrid approach of Control Theory and simulation in the analysis. LÄS MER

  3. 2. A study on emerging electronics for systems accepting soft errors

    Författare :Joakim Alvbrant; J. Jacob Wikner; Emil Nilsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic clay; Redundant systems; Memristor; Wireless sensor networks;

    Sammanfattning : Moore’s law has until today mostly relied on shrinkage of the size of the devices inintegrated circuits. However, soon the granularity of the atoms will set a limit together with increased error probability of the devices. How can Moore’s law continue in thefuture? To overcome the increased error rate, we need to introduce redundancy. LÄS MER

  4. 3. A Method for Customer-driven Purchasing : Aligning Supplier interaction and Customer-driven manufacturing

    Författare :Jenny Bäckstrand; Joakim Wikner; Eva Johansson; Martin Rudberg; Jönköping University; []
    Nyckelord :Customer‐driven purchasing; Supplier interaction; Customer‐driven manufacturing; Purchasing; Supply chain management;

    Sammanfattning : The role of a purchaser has traditionally focused on acquiring standard items at the lowest possible cost. The ability to reduce unit cost has been the key performance indicator for purchasers. Most traditional purchasing strategies thus focus on optimizing this situation, focusing on the supplier interface only and not on customer value. LÄS MER

  5. 4. Management of safety buffers for effective delivery capability

    Författare :Lisa Hedvall; Joakim Wikner; Helena Forslund; Jan Stentoft; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; management of safety buffers; reduce variations; absorb variations; manufacturing companies; variationsadministration; buffertadministration; tillverkande företag;

    Sammanfattning : A company's delivery capability is crucial for competitiveness, which becomes challenging due to variations. While some variations can be reduced, safety buffers are important for absorbing remaining stochastic variations. LÄS MER

  7. 5. Reducing and absorbing variations in a manufacturing context : A capacity management perspective

    Författare :Lisa Hedvall; Joakim Wikner; Stig-Arne Mattsson; Mats Johansson; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity management; variation management; buffer management; manufacturing companies; manufacturing planning and control; kapacitetsadministration; variationsadministration; buffertadministration; tillverkande företag; material- och produktionsstyrning;

    Sammanfattning : Variations can have substantially negative effects on performance and it is therefore important to investigate how the variations can be reduced or absorbed in an appropriate way for competitiveness. Manufacturing companies are daily exposed to variations and operations managers need to take capacity management decisions with this in mind to secure the delivery capability. LÄS MER
