A PRACTICAL AND SIMPLE MANNER OF EVALUATION OF THE EFFICACY OF IMPROVEMENT METHOD CASE IN CASE OF UNFAVOURABLE ECONOMIC SITUATIONS ON THE BASIS OF FUZZY SET THEORY
In the paper there is proposed a simple mathematical model following on from the considerations included in the theoretical papers concerning the evaluation of medical and other therapies on the ground of fuzzy sets based on lattices [2001-2004].The method allows to introduce in the evaluation procedure a convenient scale of the valuation results D
