The Greatest and the Least Eigen Fuzzy Sets in Evaluation of the Drug Effectiveness Levels

  • Elisabeth Rakus-Andersson
Part of the Lecture Notes in Computer Science book series (LNCS, volume 4029)


The eigen fuzzy set of a given fuzzy relation often corresponds to an occurrence of invariability in natural sciences. By determining the fuzzy relations as connections between pairs of symptoms we utilize the greatest and the least eigen fuzzy sets in order to find the estimates of the medicine effectiveness levels.
