workload

The term workload can refer to a number of different yet related entities.
While a precise definition of a workload is elusive, a commonly accepted definition is the hypothetical relationship between a group or individual human operator and task demands.
The assessment of operator workload has a vital impact on the design of new human-machine systems. By evaluating operator workload during the design of a new system, or iteration of an existing system, problems such as workload bottlenecks and overload can be identified. As the human operator is a central part of a human-machine system, the correction of these problems is necessary for the operation of safe and efficient systems.
An operating budget may include estimates of the expected workload for a specific activity. Work loads can vary in many different situations, but the average workload is average.
Workload can also refer to the total energy output of a system, particularly of a person or animal performing a strenuous task over…
