1. 1. Logistic Time Requirements in Fast Sea Transportation Systems

   Författare :Thore E.W. Hagman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cycle time; high speed; terminal time; performance; sailing time; total time; fuel consumption; logistic time requirement; power demand;

   Sammanfattning : The dissertation deals with logistic time requirements in fast sea transportation systems and the benefit of the application of the total time definition. The transportation engineering approach, to create new transport systems with high effectiveness, high service levels and also with high resource utilisation, has to some extent gained acceptance in the transportation industry, but it has not been fully realised that the transport system and the traffic system are not identical and that by focusing on high performance of the traffic system no guarantee is given that the transport system will become effective.

3. 2. Life Cycle Costing : Supporting companies towards a circular economy

   Författare :Marianna Lena Kambanou; Mattias Lindahl; Tomohiko Sakao; Giuditta Pezzotta; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle costing; total cost of ownership; circular strategies; products as a service; through life costing; life cycle management; circular economy;

   Sammanfattning : Increased consumption has resulted in the depletion of non-renewable resources and an explosion in waste. A circular economy proposes to sustain economic growth but decouple it from resource consumption by keeping products and materials in the economy. LÄS MER

4. 3. Environmental Considerations in the Zero-waste Valorisation of Bauxite Residue : A Life Cycle Perspective

   Författare :Peter James Joyce; Anna Björklund; Hellweg Stefanie; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment LCA ; bauxite residue; waste valorisation; Naturally Occurring Radioactive Materials NORM ; Life Cycle Thinking; LCA software; Circular Economy; Livscykelanalys LCA ; bauxitrest; avfallsvalorisering; naturligt förekommande radioaktiva ämnen NORM ; livscykeltänkande; LCA-programvara; cirkulär ekonomi; Planering och beslutsanalys; Planning and Decision Analysis;

   Sammanfattning : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

5. 4. Collision-free path coordination and cycle time optimization of industrial robot cells

   Författare :Domenico Spensieri; Stiftelsen Fraunhofer-Chalmers Centrum för Industrimatematik (FCC); []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cycle time optimization; multi-robot collision avoidance; production planning; multi-robot routing and coordination;

   Sammanfattning : In industry, short ramp-up times, product quality, product customization and high production rates are among the main drivers of technological progress. This is especially true for automotive manufacturers whose market is very competitive, constantly pushing for new solutions. LÄS MER
