Abstract

A person's work performance capability, whether physical or mental, generally declines as the day progresses. The decline in capabilities is particularly noticeable in case of highly repetitive and demanding jobs, and is primarily due to 'fatigue' - a physical and/or psychological process. To avoid the detrimental effects of fatigue, rest allowances are provided. Considerable variations exist in industrial time standards with respect to determining rest allowances. Rest allowances which are fixed as an arbitrary percentage of erroneous normal times are either inadequate or excessive. This paper reviews the various subjective and objective methods of determining rest allowances that are available to industrial engineers and ergonomists. The merits and demerits of the techniques available to determine physiological, psychological and environmental fatigue allowances are also discussed.
