abstract = {We analyze tolerance information systems as an alternative to traditional foundations of rough sets. Instead of indiscernibility, treated as equivalence in the traditional approach, we use tolerance, dropping the transitivity requirement. This way we attempt to eliminate the "paradox" whereby rough approximation of attributes is built on the foundation of sharp equivalence. We propose a scheme for synthesis of adaptive decision algorithms based on tolerance, which applies in the measurement theory, rough control, relation approximation, and so forth.},
