  3. 2. Improving Material Flows By Production Layout Conversion : A case study within the automotive industry

    M1-uppsats, Jönköping University/JTH, Logistik och verksamhetsledning

    Författare :Björn Holmdahl; [2022]
    Nyckelord :Cellular layout; Functional layout; Manufacturing; Material flow; Muda; Lean manufacturing; Production Layout; Value Stream Mapping VSM ; Continuous improvements;

    Sammanfattning : The purpose of this study is to investigate how material flows can be more efficient through the conversion from a functional-layout to a cellular-layout. The study wants to clarify how the production layout conversion can be used by organizations who are currently utilizing the functional production layout to become more efficient. LÄS MER

  4. 3. 3D Printed Lattice Structure for Driveline Applications

    Master-uppsats, KTH/Materialvetenskap

    Författare :Boyu Xue; [2021]
    Nyckelord :Lattice structure; AM Additive Manufacturing ; topology optimization; lattice optimization; NVH noise; vibration and harshness ; mechanical performance; lightweight; driveline; natural frequency; Gitterstruktur; AM additiv tillverkning ; topologioptimering; optimering av gitter; NVH buller; vibrationer och obehag ; mekanisk prestanda; lättvikt; drivlina; egenfrekvens;

    Sammanfattning : Lattice structures have received a lot of attention as cellular materials in recent years because of their outstanding properties, such as high strength-to-weight ratio, heat transfer, energy absorption, and capability of improving noise, vibration and harshness (NVH) behavior. This type of structure received a boost from additive manufacturing (AM) technology, which can fabricate geometries in practically any shape. LÄS MER

  5. 4. Aktivitetsbaserade kontor : Cellkontorets utmanare?

    Kandidat-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Jacob Cedemar; Oscar Vagman; [2018]
    Nyckelord :Activity-based office; office; productivity; health; leadership; office layout; social work environment; Aktivitetsbaserat kontor; cellkontor; produktivitet; hälsa; ledarskap; utformning; social arbetsmiljö;

    Sammanfattning : Introduction: The activity-based office has had a breakthrough in the past few years. One of the reasons for this is that the technology now allows it to work properly. The concept is a type of open landscaped office that put its main focus on the design of the physical work environment. LÄS MER

  7. 5. Produktionsförberedelse med avseende på tre nyckelfaktorer: DFA, modularisering, samt monteringssystem : En analys av framtida monteringsmöjligheter för en brandrobot av typ FUMOTM

    Master-uppsats, KTH/Industriell produktion

    Författare :Claes Eriksson; Linus Lindström; [2013]
    Nyckelord :;

    Sammanfattning : AB Realisator, ett management consulting företag med fokus på marknads- och affärsutveckling, har tidigare funnit att brandmän i dagsläget inte använder sig av någon form av robotar vid hantering av bränder. Således startades projektet FUMOTM; en robot vars främsta syfte är att gå in i bränder och filma/scanna ytan för att förenkla brandmännens arbete och potentiellt rädda liv. LÄS MER
