Improving the Efficiency of Management under the Conditions of Staff’s Psychophysiological State Changing

An approach to improving the methodological apparatus determining psychophysiological operators’ state by information from multimodal automated workstations’ input interface is represented. As a unique behavioral person’s characteristics, reflecting his psychophysiological state, it is proposed to use the jitter of the pitch period of the speech signal, the duration and period of pressing buttons on the keyboard, and the duration of the period of holding the left button "mouse", and its movement signal. The opportunity to combine partial estimates of operator’s psychophysiological state, determined as the proportion of the analyzed signal frames, on which the random jitter’s absolute value exceeds a threshold value, based on Harrington’s generalized function is showed. An example of increasing the efficiency of optimization the restraining engineering and manufacturing functions for operators on 1,6-6,8% in comparison with the known solution and the ability to automate the process of human resource management in gas production and gas transmission companies is showed.
