1. 21. 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

3. 22. 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

4. 23. 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

5. 24. A Real-Time Reactive Platform for Data Integration and Event Stream Processing

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Alexandre Tamborrino; [2014]
   Keywords : ;

   Abstract : This thesis presents a Real-time Reactive platform for Data Integration and Event Stream Processing. The Data Integration part is composed of data pullers that incrementally pull data changes from REST data sources and propagates them as streams of immutable events across the system according to the Event-Sourcing principle.

6. 25. 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
