  1. 6. Requirement and Availability of Scarce Metals for Fuel-Cell and Battery Electric Vehicles

    Författare :Ingrid Råde; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal requirement; sustainability; fuel cells; batteries; platinum; metal scarcity; resources; electric vehicles; metal availability; industrial ecology;

    Sammanfattning : Battery and fuel-cell electric vehicles (EVs) are considered as a means to meet some of the environmental and resource challenges of todays road vehicle system. EVs have the potential for zero tailpipe emissions as well as an energy efficiency higher than internal combustion engine vehicles and they can be flexible concerning primary energy source. LÄS MER

  3. 7. Modeling and analysis of restart, transport, and resource allocation in manufacturing systems using sequences of operations

    Författare :Patrik Bergagård; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete event systems; Extended finite automata; Error recovery; Manufacturing systems; Restart; Supervisory control theory; Resource allocation;

    Sammanfattning : Highly automated and flexible manufacturing systems have gained industrial popularity for their ability to combine high product volumes with high product quality. However, the process planning, the process to design and plan thetasks and actions, the operations, that constitute the manufacturing process, is a complex and time consuming process. LÄS MER

  4. 8. Information Quality Deficiencies in Manufacturing Planning and Control

    Författare :Mattias Gustavsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Key words: forecast and order information; causes and consequences of information quality deficiencies; manufacturing planning and control processes;

    Sammanfattning : Increased global sourcing and a trend towards the supply chain management perspective on manufacturing establish highly information-driven supply chains. Low levels of information quality deficiencies are an important requirement from decision-makers in manufacturing planning and control processes. LÄS MER

  5. 9. AI-Based Methods For Improved Testing of Radio Base Stations : A Case Study Towards Intelligent Manufacturing

    Författare :Cristina Landin; Amy Loutfi; Martin Längkvist; Sahar Tahvili; Brian Nielsen; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Testing of complex systems may often require the use of tailored-made solutions, expensive testing equipment, large computing capacity, and manual implementation work due to domain uniqueness. The aforementioned test resources are expensive and time-consuming, which makes them good candidates to optimize. LÄS MER

  7. 10. Additive manufacturing of Ni-based Superalloys- an analysis of parameter and strategy driven properties in Electron Beam Melting Process

    Författare :Xiaoyu Zhao; Amir Rashid; Carolin Körner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam melting; Super-alloys; process optimization; surface defects; subsurface defects; mechanical properties; thermal stresses; thermal deformation; Production Engineering; Industriell produktion;

    Sammanfattning : Metal AM processes produce significantly rough surfaces as compared to wrought or machined components. Currently, the as-EBM surfaces are extremely rough and consequently, the as-built components could not be directly used as commercial products. The state-of-the-art research has focused primarily on deeply machined (DM) samples. LÄS MER
