Wherever hazards exist, tight schedules must be met, and costs of failure are high, human judgment is needed to detect and react to malfunctions in automatic checkout equipment, incorrect program design or execution, and unexpected events. The human monitor must know exactly what the programs should be doing and what they are doing at each instant; the monitor should be able to look ahead, review the past, specify the level of detail of information, and control the rate of checkout. The moving network display with online graphical techniques (RM-5183) is outlined as an example of effective information display. Need for such a system increases as existing factory checkout systems approach the limit of their ability to handle equipment complexity and as manual systems are automated.
