Automatic identification of maintenance significant items in reliability centered maintenance analysis by using functional modeling and reasoning
Computers and Industrial Engineering (CINE), Volume 182, Issue Chttps://doi.org/10.1016/j.cie.2023.109409AbstractComplex industrial systems adopt reliability centered maintenance (RCM) for maintenance optimization to improve safety and reduce maintenance cost. Preserving function is the core maintenance principle, yet the function concept has not been ...
Highlights- RCM is all about function analysis and failure analysis.
- Existing RCM efforts are labor-intensive and experience-dependent.
- MFM provides systematic approach to represent sufficient function and failure knowledge for RCM.
- Causal ...

A functional feature modeling method
Advanced Engineering Informatics (ADEI), Volume 33, Issue CPages 1–15https://doi.org/10.1016/j.aei.2017.04.003With the advances in CAD technology, it has been increasingly convenient to model product shapes digitally. For example, in a feature-based parametric CAD system, the product shape could be parameterized and thus altered with the change of parameters. ...

Modified thalamocortical model: A step towards more understanding of the functional contribution of astrocytes to epilepsy
Journal of Computational Neuroscience (SPJCN), Volume 33, Issue 2Pages 285–299https://doi.org/10.1007/s10827-012-0386-8It is evident that the cortex plays a primary role in seizure generation. At the same time, various experimental results clearly confirm that thalamic neurons are also actively involved in seizure generation and spreading. On the other hand, recent ...
