Full Load hour is a measure of the degree of utilisation of a technical system. [1] [2] [3] Full load hours refer to the time for which a plant would have to be operated at nominal power in order to convert the same amount of electrical work as the plant has actually converted within a defined period of time, during which breaks in operation or partial load operation can also occur.
In scheduling, tardiness is a measure of a delay in executing certain operations and earliness is a measure of finishing operations before due time. The operations may depend on each other and on the availability of equipment to perform them.
For example, if 32 hours of billable time are recorded in a fixed 40-hour week, the utilization rate would then be 32 / 40 = 80%. Note that with this second method it is possible to have a utilization rate that exceeds 100%. If 50 hours of billable time are recorded in a fixed 40-hour week, then the utilization rate would be 50 / 40 = 125%.
Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. This is related to an activity rate which is a similar calculation used in activity-based costing. A pre-determined overhead rate is normally the term when using a single, plant-wide base to calculate and apply overhead.
The following table provides examples of the labor information tracked by overall labor effectiveness organized by its major categories. Using this labor information, manufacturers can make operational decisions to improve the cumulative effect of labor availability, performance, and quality.
In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. [1] It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may ...
The mean time between failures (MTBF, /) is often reported instead of the failure rate, as numbers such as "2,000 hours" are more intuitive than numbers such as "0.0005 per hour". However, this is only valid if the failure rate λ ( t ) {\displaystyle \lambda (t)} is actually constant over time, such as within the flat region of the bathtub curve.
A man-hour or human-hour is the amount of work performed by the average worker in one hour. [1] [2] It is used for estimation of the total amount of uninterrupted labor required to perform a task. For example, researching and writing a college paper might require eighty man-hours, while preparing a family banquet from scratch might require ten ...
