This is calculated as (Amount of overhead/Material cost)x 100 If the production overhead is 3,000 and the material cost is 10,000 then the absorption rate will be (3000/10000)x 100 = 30% Now for a product if the material cost is 1000 then the overhead cost is 300. so the total cost would be 1300.
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 Failures In Time (FIT) rate of a device is the number of failures that can be expected in one billion (10 9) device-hours of operation [17] (e.g. 1,000 devices for 1,000,000 hours, or 1,000,000 devices for 1,000 hours each, or some other combination).
Following strong initial uptake, ABC lost ground in the 1990s compared to alternative metrics, such as Kaplan's balanced scorecard and economic value added.An independent 2008 report concluded that manually driven ABC was an inefficient use of resources: it was expensive and difficult to implement for small gains, and a poor value, and that alternative methods should be used.

The Standard Time is the product of three factors: Observed time: The time measured to complete the task. Performance rating factor: The number pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal.
The first system fails after 100 hours, the second after 120 hours and the third after 130 hours. The MTBF of the systems is the average of the three failure times, which is 116.667 hours. If the systems were non-repairable, then their MTTF would be 116.667 hours.
A given Work Center is scheduled to run for an 8-hour (480-minute) shift with a 30-minute scheduled break. Operating Time = 450 Min Scheduled – 60 Min Unscheduled Downtime = 390 Minutes The Standard Rate for the part being produced is 40 Units/Hour or 1.5 Minutes/Unit The Work Center produces 242 Total Units during the shift.
Alternatively – the ratio of a reference man-hour rate to a selected man-hour rate. Example: selected rate = 0.104, reference rate = 0.125, productivity factor = 0.125/0.104 = 1.20. A productivity factor is often used to adjust a set of standard or normal (norm) production or man-hour rates to a set of rates for a specific project, location ...
