1. 1. An Ontological Approach to support Knowledge Sharing between Product Design and Assembly Process Planning (APP)

   Författare :Baha Hasan; Jan Wikander; Mauro Onori; Jonathan C. Borg; Jos'e Barata; Pär Mårtensson; Monica Bellgran; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; knowledge sharing; Ontology; semantics; assembly knowledge; assembly design and assembly process planning.; Production Engineering; Industriell produktion;

   Sammanfattning : Modern manufacturing organizations have to cope with several critical issues arising from the need for mass customization such as short product life-cycles, an increasing number of product variants and frequently changing customer requirements. One of the main factors that could aid overcoming those challenges is the use of information and communication technology (ICT) applications over a collaborative manufacturing environment, in which all stakeholders share and exchange knowledge across different manufacturing domains and applications.

3. 2. Planning Robotic Assembly Sequences

   Författare :Domenico Spensieri; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; robot routing and scheduling; path planning; Assembly planning; geometrical variation; cycle time optimization;

   Sammanfattning : In the automotive industry, short ramp up times and high product quality drive the development toward state-of-the-art solutions both in the research and industrial perspective. In addition to that, a sustainable industry requires optimized equipment utilization, in terms of materials used and consumed energy. LÄS MER

4. 3. Assembly processes and materials supply systems design

   Författare :Christian Finnsgård; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packaging; materials exposure; Lean production; materials handling; materials supply; production system; assembly;

   Sammanfattning : Lean production has over the last decades emerged as the most important paradigm for production, with the assembly processes in focus, including the objective to minimize non-value-adding work. Thus, much attention has been on the work of the assembly operator. LÄS MER

5. 4. Nucleolar Ribosome Assembly

   Författare :Fredrik Lackmann; Lars Wieslander; Denis Lafontaine; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; RNA; Nucleolus; Molecular Biology; molekylärbiologi;

   Sammanfattning : Ribosomes are macromolecular machines that are responsible for production of every protein in a living cell. Yet we do not know the details about how these machines are formed. The ribosome consists of four RNA strands and roughly 80 proteins that associate with each other in the nucleolus and form pre-ribosomal complexes. LÄS MER

7. 5. Information Requirements in a Proactive Assembly Work Setting

   Författare :Jessica Bruch; Christer Johansson; Johan Karltun; Magnus Wiktorsson; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Proactive Behaviour; Information; Assembly; Uncertainty; Change; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

   Sammanfattning : Due to the increasingly competitive climate, the on-the-job behaviour of an operator becomes more and more essential for the success of a manufacturing company.  In working contexts, which are dominated by changes and uncertainty, knowledge-based behaviour and work role aspects that cannot be formalized, proactive behaviour of the operator can contribute to competitive advantages.
