LIKELIHOOD-OF-ACCOMPLISHMENT SCALE FOR A SAMPLE OF MAN-MACHINE ACTIVITIES.
Abstract
Techniques for use in man-machine effectiveness analysis are limited by the current lack of empirical data on human performance capabilities in complex systems. To explore an interim solution to that problem, a paired comparison scaling approach was employed to obtain relative estimates of human capability to perform 100 man-machine activities. An analysis of variance procedure revealed that a satisfactory fit of the linear paired comparison model to the data was obtained. Within-judge consistency and between-judge agreement was determined to be satisfactory. The resultant scale values were transformed to a probability dimension using a log transform function and two data points. A technique for expanding the basic store of data using a key stimulus approach was suggested. Follow-up study with empirically-derived performance data is required to test the validity of the scale values obtained and the transformation equation. (Author)
