  2. 1. Improving energy efficiency in logistics systems: On the road to environmental sustainability

    Author : Jessica Wehner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road freight transport; service modularity; service logic; logistics fulfilment; Capacity utilisation; point of consumption; first mile; service blueprint; household waste; distribution structure; system levels; systems perspective; value co-creation; last mile;

    Abstract : Logistics are essential to efficiently managing the flow of materials and products between various nodes that operate in multiple systems. In that process, the activities of moving and storing materials and products, especially through road freight transport, consume significant energy resources and emit greenhouse gases that harm the environment.

  4. 2. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

    Author : Stavros Tzilis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

    Abstract : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.

  5. 3. Energy Storage Systems in Electrical Distribution Grids : Analysis and implementations of use cases for service stacking

    Author : Johannes Hjalmarsson; Cecilia Boström; Karin Thomas; Louise Ödlund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ancillary services; congestion management; distribution grids; energy storage systems; scheduling optimization; service stacking.;

    Abstract : This Ph.D. thesis investigates the possibility of using energy storage systems for multiple services by implementing service stacking, with special emphasis on congestion management in distribution grids. READ MORE

  6. 4. Car distribution organization : strategic issues in four configurations

    Author : Anders Parment; Björn Axelsson; Linköpings universitet; []
    Keywords : car industry; distribution; competition; brands; coordination; strategic issues; distribution chains; lean distribution; retail geography; market knowledge; bilmarknaden; distribution; personbilar; marknadsföring; köpbeteende; varumärke; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : This study is concerned with car distribution organization, a context characterized by overcapacity, intense competition, and manufacturers heavily focusing on brands. In the study, different distribution solutions are investigated through applying a framework of four strategic issues. READ MORE

  7. 5. Use of the CIM framework for data management in maintenance of electricity distribution networks

    Author : Lars Nordström; Torsten Cegrell; Pekka Verho; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asset Management; Electricity Distribution Networks; Information Systems; Data Quality; Power System Modeling; Enterprise Architecture; Common Information Model; Ontology; Systems engineering; Systemteknik;

    Abstract : Aging infrastructure and personnel, combined with stricter financial constraints has put maintenance, or more popular Asset Management, at the top of the agenda for most power utilities. At the same time the industry reports that this area is not properly supported by information systems. READ MORE
