MULTIPLE CRITERIA FOR ASSESSING TRACKING PERFORMANCE: THE ASSESSMENT OF TEP INPUT TRACKING.
Abstract
This report suggests that simultaneous measurement, recording, and reporting of many, rather than one, criteria of performance for step tracking and discrete setting tasks will increase both the present and the future value of an experiment. An illustrative example is given from the literature on servo-analysis as well as one from the human factors literature. Questions are raised as to the validity of extrapolation from a tracking experiment in which one criterion is used to a system where another would be more appropriate. A digital computer program for the simultaneous computation of a number of measures of step tracking performance was devised and applied to a typical experiment on step tracking. The results indicate that, as expected, different combinations of gain and lag are optimum for different criteria (where optimum means producing the least value of the criterion) and that therefore research aimed at solutions of operational problems should employ a variety of measures of performance.
