  1. 16. Evaluating An Interactive Troubleshooting System for Heavy Vehicles with Limited Historical Data

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Khair Ghazie; [2017]
    Keywords : ;

    Abstract : Today’s trucks are built to be modular in order to fit the customer’s specific needs.This means that no two vehicles are  alike, and that makes it difficult to create universal models for diagnosis. READ MORE

  3. 17. An Evaluation of Mixed Criticality Metric for Mechatronics Systems

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ruoyu Zhang; [2016]
    Keywords : ;

    Abstract : In the thesis, we studied mechatronics systems which integrate tasks (applications) with different level of criticality on a common embedded system. The integration aims to reduce hardware cost (less processors and other components) and the weight and volume of the system. The power consumption of the system would be also reduced. READ MORE

  4. 18. Automated Fault Tree Generation from Requirement Structures

    University essay from Linköpings universitet/Fordonssystem

    Author : Johan Andersson; [2015]
    Keywords : fault tree; Scania; safety analysis; bayesian network; requirement structure;

    Abstract : The increasing complexity of today’s vehicles gives drivers help with everything from adaptive cruisecontrol to warning lights for low fuel level. But the increasing functionality also increases the risk offailures in the system. To prevent system failures, different safety analytic methods can be used, e.g. READ MORE

  5. 19. Cost effective optimization of system safety and reliability

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Author : Joakim Bergström; Hampus Nilsson-Sundén; [2015]
    Keywords : cost effective; optimization; system safety; reliability; fault tree; fault tree analysis; reliability block diagram; maltab; excel; optimering; systemsäkerhet; tillförlitlighet;

    Abstract : A method able to analyze and optimize subsystems could be useful to reduce project cost, increase subsystem reliability, improve overall aircraft safety and reduce subsystem weight. The earlier the optimization of development of an aircraft in the design phase can be performed, the better the yield of the optimization becomes. READ MORE

  6. 20. Simulating production risk at Volvo Powertrain - Developing a simulation tool for decision making

    University essay from Lunds universitet/Förpackningslogistik

    Author : Magnus Cederlund; [2014]
    Keywords : Risk Management; Supply Chain Risk Management; Fault Tree Analysis; Preliminary Hazard Analysis; Lean Production; Risk Matrix; World Class Manufacturing; Fire Safety; Volvo Powertrain; Business and Economics; Technology and Engineering;

    Abstract : How can a small fire at a subcontractor in the USA lead to a multimillion dollar loss at a Swedish telephone company, and how can a single machine breakdown lead to a complete production stop at a production company? With today logistics and production trends, where terms such as Lean Production, Six Sigma, 5S, and World Class Manufacturing are used every day, production companies are introducing streamline production facilities and supply chain where goods and raw material are delivered just in time, where buffer zones are reduced, and where suppliers are reduced to a single source. These are trends that strengthen companies’ competitiveness, but it also makes companies more vulnerable to risk events. READ MORE
