Abstract
An approach which combines the salient features of predetermined time and motion systems and a simulation modeling algorithm is presented for the evaluation and assessment of job performance aids (JPAs). Description of the approach, its assumptions, and the computer algorithm used are discussed and detailed. The validity of the approach was ascertained in a companion experimental study which evaluated four types of JPAs: (1) all print, (2) all pictorial, (3) print and pictorial combined, and (4) a hybrid group which used pictorial on easy tasks and pictorial on the more difficult tasks. Results of the validation study demonstrates the accuracy and adequacy of the approach for dealing with JPA design problems. The approach, as presented, can be used to optimally locate points of need for JPAs within maintenance systems. It can also be used to study the effects of various scheduling and allocation policies on human performance and its reliability, while utilizing various alternatives of JPA design.
