Human Performance in Manual Process Control

  • Colin G. Drury
Part of the NATO Conference Series book series (NATOCS, volume 1)


Manual Process Control tasks in industry are legion. The operator must control such a complex process in real time with strict limitations on any deviations from optimum performance if the process is to be economically viable. Chemical processes (Kragt & Landeweerd, 1974), steel making processes (Bainbridge et al, 1968)*, paper mills (Attwood, 1970)*, and glass manufacturers (Drury & Hill, 1973) have been studied with a view to improving operator performance.
