Exercises
1. Given that we are working with the domain of “age” of a population of people,
define a set of fuzzy membership functions over the domain that might be
appropriate for use by an insurance company determining risk of Alzheimer’s
disease, which affects mainly older people. Repeat the exercise for use by a
medical organization for diagnosing appendicitis, which is assumed for this
exercise to affect people regardless of age. Justify the number and distribution
of fuzzy sets.
2. Fuzzy sets V and W are defined on the same universe of five individuals as follows:
V =
