We introduce two-dimensional logics based on Łukasiewicz and Gödel logics to formalize reasoning with graded, incomplete and inconsistent information. The logics are interpreted on matrices, where the common underlying structure is the bi-lattice (twisted) product of the [0, 1] interval. The first (resp. second) coordinate encodes the positive (resp. negative) information one has about a statement. We propose constraint tableaux that provide a modular framework to address their completeness and complexity.
