1. 1. Root cause analysis for resilient production systems through Industry 4.0 technologies

   Författare :Adriana Ito; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; root cause analysis; Industry 4.0; production disturbances; resilient systems;

   Sammanfattning : Creating and developing resilient production systems is critical if manufacturing companies are to thrive in a globally competitive market. Being flexible and agile, resilient systems can avoid, withstand, adapt to and recover from disturbances. A crucial ability is learning from experienced disturbances so they can be avoided in future.

4. 3. How to Reduce Geometrical Variation in Assembled Products

   Författare :Johan Carlson; Göteborgs universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; assembled products; body-in-white BIW ; dimensional variation; geometrical variation; fixtures; fixture diagnosis; locating schemes; multivariate analysis; rigid body motion; robust design; root cause; quality; root cause;

   Sammanfattning : Vehicle problems, such as wind noise, water leakage and door closing effort are examples of quality and functionality defects that are controlled by the dimensional accuracy of the structural frame of an auto body. The aim of this thesis is towards methods for reducing geometrical variation in assembled products in the automotiv other industries. LÄS MER

5. 4. Learning for safety in health care and air traffic control

   Författare :Sven Ternov; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Risk management; accident models; complex systems; health care; air traffic control; MTO analysis; DEB-analysis; proactive risk analysis.;

   Sammanfattning : Introduction Risk management in enterprises, organisations and companies has had a long and complicated history. During the eighties, and at least during the beginning of the nineties, the notion concerning risk management was that if an accident happened in an otherwise perfect system it was due to the human operator in some way being the cause of the error.

7. 5. Machine learning-based diagnostics and observability in mobile networks

   Författare :Tobias Sundqvist; Erik Elmroth; Monowar H. Bhuyan; Rolf Stadler; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; Root cause analysis; Observability; Machine learning; Radio Access Network; 5G; Computer Science; datalogi;

   Sammanfattning : To meet the high-performance and reliability demands of 5G, the Radio Access Network (RAN) is moving to a cloud-native architecture. The new microservice architecture promises increased operational efficiency and a shorter time-to-market, but it also comes with a price. LÄS MER
