As the title implies, the article describes the issues of CNC machines’ technical operability evaluation in real time. The scientific research relevance of this topic has been substantiated, and suitable monographs, articles, and regulations have been scanned. The types and causes of the automated technological equipment failures on the processing industries have been analyzed. The authors proposed a new approach to estimating the probability of equipment failure using the continuous-valued logic of antonyms, the mathematical tools technique of which allows making calculations based on linguistic variables in a convenient and informative form. The technical operability of the equipment is considered the example of a CNC machine, in particular, its electromechanical subsystem. A general solution pattern has been developed; attempts are made to present mathematical simulation. Three methods for technical operability evaluation using weighting factors are proposed. The developed methods and models make it possible to get away from traditional statistical calculations of reliability and to diagnose the state of automated equipment in a real-time mode.
