Bi-fuzziness, Incompleteness, Inconsistency, Truth and Falsity Based on Saturation and Ignorance Functions. A New Approach of Penta-Valued Knowledge Representation
Vasile Pătrașcu · 2012
This paper presents a new five-valued knowledge representation of bipolar information. This representation is related to a five-valued logic that uses two logical values of truth (true, false) and three logical values of uncertainty (incomplete, inconsistent and fuzzy). The new approach is based on the concept of saturation function and ignorance function. In the framework of five-valued representation new formulae for union and intersection are constructed. Also, the paper presents a short application related to fuzzy preference modeling and decision making.
