Basic Definitions of the Fuzzy Sets Theory
In the classic theory of sets, very precise bounds separate the elements that belong to a certain set from the elements outside the set. In other words, it is quite easy to determine whether an element belongs to a set or not. For example, if we denote by A the set of signalized intersections in a city, we conclude that every intersection under observation belongs to set A if it has a signal. Element x’S membership in set A is described in the classic theory of sets by the membership function μA(x), as follows:
