Abstract:

A program evaluating the application of data capture techniques to the entry of shipping data at MAC air cargo terminals is in progress. As a part of this program six airmen from the truck dock of the MAC air cargo terminal at Dover AFB participated at MITRE in tests comparing three alternative modes of data entry an on-line keypaddisplay, a digital recorder, and manual checksheets. Data items were entered from photographed shipping labels simulating truck loads of cargo varying in shipment-to-piece ratio and availability of advance shipment information. Performance measures included data entry time required for each test load, for characteristic entry sequences, and for the input of individual data items. Accuracy of performance was measured in terms of the frequency of different entry errors in data content and format, and detectioncorrection of errors in advance data. Recorded evaluations by the MAC test operators confirmed a strong preference for the on-line mode for potential use in truck dock data entry. A follow-on program of laboratory and field testing is recommended. Author
