Constructing the plausible descrirtion logic by blurring the concepts with rough sets

The logical representation formalism is proposed, based on plausible description logic that is a specialization of the lattice description logic where incompleteness, inaccuracy and qualitative uncertainty can be expressed using rough and fuzzy concepts by evaluating on a compact bounded lattice de Morgan. It is shown that the logical formalism of the plausible description logic is complementary with the plausible tree event’s networks, and can be used in real-time systems.
