Fuzzy sets that part the input and output universes of discourse
The fuzzy relation resulting from the fuzzy rules that stands for the diagnostic is
depicted in Fig. 16.6a. Observe the level curves obtained with the projection of the
set of rules that part the input-output space of the problem. There are three fuzzy
regions corresponding each to a fuzzy rule that are aggregated by using the logical
operator of disjunction, after the Cartesian product be obtained with the logical
operator of conjunction. The choice of the logical operators (t-norm and t-conorm)
directly affects the geometry of the fuzzy inference mechanism, determining the
intersection of the fuzzy regions. In this example the conjunction operator is chosen
to be the
min
while the disjunction operator is the
max
