"The general problem of optimum division of duties between two or more men who are performing essentially the same functions in a complex man-machine system was investigated. Six two-man pattern-feeder control teams were employed in an experiment which was designed to evaluate three methods of control assignment and two procedures for exchange of control assignment in a simulated radar approach control system. Assignment of control on the basis of aircraft destination was found to be superior to assignment by alternation or assignment by sector of entry. There was some evidence that, a condition of partial restraint on the exchange option impaired system performance, although the data were not conclusive. An explanatory principle based on the balance of demand on operator capacity across task segments was suggested as one which was compatible with the data."--Abstract.
