Abstract
The theory of α-truth degrees in 3-valued Pre-rough logical system is studied in this paper. Firstly, the definition of α-truth degrees is proposed. Secondly, the general reasoning rules about α-truth degrees are obtained. Lastly, the α-similarity degree and α-pseudometric between two formulas are defined by means of the concept of α-truth degrees, and their properties are discussed. This offers a theory framework for approximate reasoning in 3-valued Pre-rough logic.
