	To assess an diagnostic system for electromechanical system and choose its best variant requires formulate of criterion determination. This process consists of formulating the criterion function and then finding critical variable values. Technological, economical and, sometimes, praxeologic criterions arepresents in this report. Basing on the consideration should be applied when data used for calculation are multivalent (fuzzy) nature. The idea of linguistic variables is identified with the idea of linguistic terms. This means: - an appropriate of number of linguistic variables shall be determined, - a value of the membership function is subordinated to each linguistic variable. The set of linguistic variables describing the diagnostic state of electromechanical systems is admitted depending of the origin if its components: good – medium – bad. The upper number of linguistic variables should be suggested. In practice distinct limits exist. These limits may be set by the perceptive capacity of person responsible for the assessment of system. This number of linguistic variables applied in the diagnostic of a elektromechanical system is determined at three (good –medium – bad), maximum at five (good – mediocre – medium – weak – bad). The thus suggested number of linguistic variables may be applied rather easily for arriving at multivalent logics. However, the rules of bivalent logics impell the choice of only two state: good – bad.
