  1. 1. Performance problem diagnosis in cloud infrastructures

    Detta är en avhandling från Umeå : Department of Computing Science, Umeå University

    Författare :Olumuyiwa Ibidunmoye; Umeå universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Performance; Performance anomalies; Performance bottlenecks; Cloud infrastructures; Cloud Computing; Cloud Services; Cloud Computing Performance; Performance problems; Performance anomaly detection; Performance bottleneck identification; Performance Root-cause Analysis; Computer Systems; datorteknik; Computer Science; datalogi;

    Sammanfattning : Cloud datacenters comprise hundreds or thousands of disparate application services, each having stringent performance and availability requirements, sharing a finite set of heterogeneous hardware and software resources. The implication of such complex environment is that the occurrence of performance problems, such as slow application response and unplanned downtimes, has become a norm rather than exception resulting in decreased revenue, damaged reputation, and huge human-effort in diagnosis.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel computing; performance monitoring; performance tools; event flow graphs; Datalogi; Computer Science;

    Sammanfattning :   A considerably fraction of science discovery is nowadays relying on computer simulations. High Performance Computing  (HPC) provides scientists with the means to simulate processes ranging from climate modeling to protein folding. LÄS MER

  3. 3. Reliability analysis and cost modeling of degrading systems

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Saurabh Kumar; Luleå tekniska universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Degradation is an on-going process in systems, equipments and components subjected to various stresses and adverse operating conditions. The factors influencing the degradation process may adversely affect the system or component performance. LÄS MER

  4. 4. Physics-of-failure based performance modeling of critical electronic components

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Adithya Thaduri; Luleå tekniska universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Reliability prediction of the electronic components used in industrial safety systems requires high accuracy and compatibility with the working environment. The traditional reliability prediction methods that draw on standard handbooks such as MIL-HDBK 217F, Telcordia, PRISM etc. LÄS MER

  5. 5. Towards strategic development of maintenance and its effects on production performance A hybrid simulation-based optimization framework

    Detta är en avhandling från Skövde : University of Skövde

    Författare :Gary Linnéusson; Högskolan i Skövde.; Högskolan i Skövde.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic development; maintenance behavior; maintenance management; sustainable change; tradeoff optimization; system dynamics; discrete event simulation; problem structuring; multi-objective optimization; decision support; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Managing maintenance in manufacturing within an economical short-termism framework and taking the consequential long-term cost effects into account is hard. The increasing complexity of managing maintenance and its impact on the business results calls for more advanced methods to support long-term development through effective activities in the production system environment.
