Restrictions of P-fuzzy switching functions

A P-fuzzy switching function is a meaningful class of fuzzy switching functions that is representable by a logic formula consisting of prime implicants. A restriction of a P-fuzzy switching function is a mapping of the restricted domain within a finite subset of [0,1]ⁿ . Considered is a positive use of fuzziness in inferences supposing that human knowledge can be represented by P-fuzzy switching functions, which have an acceptable property called uniformity. The main results are the necessary and sufficient conditions for a restriction to be represented by a P-fuzzy switching function, and to be uniquely determined with a P-fuzzy switching function
