1. 1. On Risk Management of Electrical Distribution Systems and the Impact of Regulations

   Författare :Carl Johan Wallnerström; Lina Bertling; Roland Eriksson; Kjell Sand; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Distribution System; Maintenance Management; Project Planning; Regulation; Reliability Analysis; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Risk Analysis; Risk Management; Risk Methods; the Network Performance Assessment Model NPAM ; Electric power engineering; Elkraftteknik;

   Sammanfattning : The Swedish electricity market was de-regulated in 1996, followed by new laws and a new regulation applied to the natural monopolies of electrical distribution systems (EDS). These circumstances have motivated distribution systems operators (DSOs) to introduce more comprehensive analysis methods. LÄS MER

3. 2. Redundancy and Robustness Quantification of Bridge Systems based on Reliability and Risk Approaches

   Författare :Silvia Sarmiento; Gabriel Sas; Jaime Gonzalez-Libreros; Robert Hällmark; Thomas Blanksvärd; Sebastian Thöns; John Leander; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Existing bridges; reliability; risk; metamodel; Finite Element Modeling; Model tests; Byggkonstruktion; Structural Engineering;

   Sammanfattning : Over the last few decades, evaluating the performance of existing structures has become increasingly important, particularly as the number of bridges reaching their design life continues to rise. As a result, there is a growing need for effective and accurate procedures to guide the assessment of the current structures' capacity and safety levels to implement appropriate maintenance and rehabilitation strategies.

4. 3. Reliability-centred maintenance : identification of management and organisational aspects when introducing RCM

   Författare :Fredrik Backlund; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Sammanfattning : Increased demands on productivity, quality and cost-efficiency affecting manufacturing trends towards increased complexity and higher degree of process automation. A major break down in such a manufacturing system may generate severe damage on productivity, environment and personnel. LÄS MER

5. 4. Supply Chain Risk Management : Identification, Evaluation and Mitigation Techniques

   Författare :S.Nurmaya Musa; Ou Tang; Jan Olhager; David Zhang; Linköpings universitet; []
   Nyckelord :Supply chain risk management; risk analysis; risk control; co-citation; system dynamics; modelling;

   Sammanfattning : Supply chains have expanded rapidly over the decades, with the aim to increase productivity, lower costs and fulfil demands in emerging markets. The increasing complexity in a supply chain hinders visibility and consequently reduces one’s control over the process. LÄS MER

7. 5. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

   Författare :Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Sammanfattning : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. LÄS MER
