Efficiency assessment of the rule and model bases in decision support systems

Abstract

In the article new indices for e±ciency assessment of the intelligence rule and model bases in decision support systems (DSS) are suggested. These indices are rule base certainty and coverage, rating class e±ciency, rating e±ciency. Formulae for these coe±cients calculation are deducted, received with use of rough sets theory and DSS e±ciency assessment experience. Recommendations on their practical using are given
