ASSESSMENT OF FUNCTIONAL DEGENERATION PROCESS OF MULTICHANNEL SYSTEM INCORPORATED A HUMAN OPERATOR
Annotation
Human-operated multichannel functional system is considered to evaluate the possibility of the system degeneration in respect of the individual-operator as well as in respect of the team of individuals forming the multichannel system. The multichannel functional system dimension is determined by the number of individuals involved; the study is based on descriptions of the individuals’ activities using an additive mathematical model of the process "warming-up — fatigue" during the working half-shift. The causes of degeneration are formulated; technical component and the anthropogetic factor are considered as the main. Method for estimating the degeneration process is based on the use of degeneration functional in relation to the criterion matrix. The matrix is constructed in a diagonal form characterizing the normal functioning of the multichannel system, while the emergence of the off-diagonal elements is considered as one of the reasons for its degeneration. Thus, diagonality of the criterion matrix is a necessary but insufficient condition for preservation of equal-pace functioning of separate channels of the system. Accounting for the interval factor inherent in the human operator allows to control the violation of the synchrony of multichannel system. It is proposed to use the integral representation of degeneration functional, which must contain a multiplicative component considering the possible decline of output of multichannel functional system.
