Mathematical methods for pattern recognition and algorithms for the classification of diseases based on them are widely used to solve problems of medical diagnostics [1]. In [2], in order to classify functional disorders of the gastrointestinal tract, an algebraic model of the Kora algorithm was applied. In [3–5] it was shown that to solve many problems of medical diagnostics possibilistic methods for making a medical diagnosis are much more efficient. The present work considers a comparative analysis of probabilistic and possibilistic models of diagnostics, as well as Kora algorithms and the results of their application to solving problems of acute appendicitis diagnostics.
