Abstract

Job analysts and designers require efficient techniques to quickly and accurately evaluate the reach requirements of a job with respect to individual and population reach capabilities. Interactive computer graphics may be used to provide job analysis capabilities in a manner which minimizes the time for an analyst to collect and analyze data, and recommend job modifications. These computer aided job design facilities require analytical models to support the job analysis function. This paper focuses on analytical models for estimating maximum reach capabilities. A three dimensional spherical harmonic model is used to describe reach capabilities for several different populations and job configurations. The results indicate that the model provides very accurate estimates of maximum reach capability. The model supports computer aided job analysis procedures efficiently with respect to the analyst's time.
