A fatigue management scheme is a set of rules that specify the number of breaks of a certain duration that must occur within a given time interval (period). Each rule consists of the following:
Number of Breaks
The number of breaks required by the rule.
Duration of Break
The duration of the break.
Interval of Break
The time interval (period) in which the break must occur.
Example A fatigue management scheme may have the rule: A single 15 minute break every 2 hours. Here, the number of breaks is 1, the duration of the break is 15 minutes and the interval in which the break must occur is 2 hours.
