Advantages and disadvantages of methods based on physical models
Diagnosis and failure prognosis methods based on physical models

One of the major advantages of the physical model approach is the ability to take into account, in the monitoring process, the physical phenomena that govern the behavior of the equipment and its constituent materials. This knowledge of physical laws makes it possible to reduce the number of parameters, and therefore sensors, by performing monitoring, diagnostic and prognostic tasks only on the relevant descriptors. The use of physical models, coupled...
