Rules and usable patterns
Rules generated, e.g.:
IF
- J_43_XI_21091VF_v_gt95p and
- J_43_LIC_00419SP_j_gt95p
THEN
- low_water_closed(0.5, 0.7)
(within 0.5hour, probability 0.7)
SLIDE 30
The expert: Rule visualisation
SLIDE 31
The operator: Supervision and Diagnostics
SLIDE 32
SLIDE 33
- The solution comes up with a set of rules
- Each rule warns against a problem coming up
- Rules = model
=> set in production
