Figure 5.32 Firing the first pricing model rule.

This is an unconditional rule. Figure 5.32 shows the result of executing

the first unconditional rule.

Because the outcome fuzzy region is empty, the High fuzzy set is

simply copied into the outcome fuzzy set. This essentially “primes the

pump” for the remainder of the unconditional. If we Anded the fuzzy set

High with an empty fuzzy set (whose membership values are all zero),

we would produce nothing but another empty fuzzy set.

Rule 2

Rule 2 is as follows.

Our Price must be Low

This is also an unconditional rule. Figure 5.33 shows the result of

executing the second rule.
