The device works as follows.

Preliminary, using the sensor 36, the researcher sets the required value of the reliability value of the operator's quality assessment, and using the sensor 37, determines the position of the membership function of the operator’s professional competence, the type of which and position are determined by the existing requirements to the quality of his activity (Fig. 5). ).

The discrete signal characterizing the quality of the operator’s performance (its temporal or exact characteristic and implementation) goes to the distributor 10 and through the normally open key 11 to the adder 1. from the output of the adder 1, since its input is shunted by the corresponding feedback element of the switch 8 A signal equal to the expectation of the input signal after implementation is removed. The input signal by means of the formation circuit of the modulator 4 and the quad 5 is transformed and fed to the adder 2, -c the output of which relieves the voltage converted by connecting in the feedback circuit of the adder 2 of the corresponding feedback element of the modular floor switch 9. The adder 6 enters the signal is equal to the signal module at the output of the adder 1, since the circuit between them includes the circuit for forming the module of the former 3. The adder 6 simultaneously builds one of the components in a square and attraction root of radical expression.

The input signal received by the distributor 10 is registered and fed to the distributor 7, which switches the feedback elements of the switches 8 and 9, adders 1 and 2, and also feeds the keys 12 and 13, through which the calculation results are printed after processing each implementation.

At the same time, the value of the parameters of the expectation and the standard deviation from the inputs of the keys 12 and 13 are fed to the inputs

converter 15, which also receives the voltage from block 17, is proportional to the required value of the reliability of the operator's quality assessment. The functional converter 15 generates a voltage proportional to the value of the guarantee coefficient corresponding to the required probability of the evaluation reliability and static indicators for evaluating the quality of the operator’s work. The voltage developed by the converter 15 is fed to the regulating input of the amplifier 14, changing in direct proportion to its gain. At the output of the amplifier 14, a voltage is formed which then adds up in the adder 16 with the voltage of the switch 12.

Thus, at the output of the adder 16, a signal is formed that corresponds (at the developed scale) to the value of the guaranteed assessment of the quality of the operator's activity, which meets the required probability value. The value of the guaranteed rating in each measurement cycle is fixed by the indicator 38.

After the end of the assessment of the quality of the operator's work, the researcher presses the button of the imager 26. In this case, the trigger 19 is transferred to a single state. The generator 20 begins to form counting pulses. Simultaneously with pressing the Start button of the imager 26, the counter 21 is reset. After releasing the button, the outputs 21 of the counter 21 generate a numeric code that goes to the control inputs of the commutator 22, which, in accordance with the code, switches the resistances from the resistance box to the feedback ceri adder 23. The resistances in the resistivity store of the switch 22 are selected so that at the output of the adder 23 the voltage complies with the law of changing the membership function of a professional operator of clarity on the value of its guaranteed quality assessment "

The change in the position of the membership function on the axis is accomplished by a corresponding change in the voltage at the output of the sensor 37 (Fig. 5).

The code value of the number on the counter 21 is converted to a voltage in

10 .4

converter 25. At the time of equal voltage at the output of converter 25 and voltage at the output of the adder 16, proportional to the guaranteed assessment of the quality of the operator, a positive signal is generated at the output of the comparator 24, which triggers t9 to zero, and a breakdown occurs Oscillator 21. The signal taken at this time from the adder 23 determines the degree of professional suitability of the operator.

Functional Converter 15 operates as follows.

Voltage is applied to the transducers 30-32. The code values of the parameters from the outputs of the converters 30-32 go to the switch 33, which switches the resistances in the feedback circuit of the amplifier 35, selected so that, in accordance with the codes from the converters 30-32, the output of the amplifier 24 proportional to the value of the missing parameter of the guarantee ratio. Using the sensor 34, an appropriate conversion scale is selected.

Thus, the proposed device makes it possible to determine a guaranteed assessment of the quality of the operator’s performance, which meets the required reliability value, as well as its degree of professional suitability, taking into account the vagueness of making decisions about the operator’s professional fitness and the nature of the requirements imposed on it by specific conditions. .

The use of such a cumulative assessment allows us to exclude incorrect constrictions about the quality of work and professional suitability of the operator, due to insufficient research experience of the investigator or his objective errors.
