Standard time (manufacturing)

From Wikipedia, the free encyclopedia

In business efficiency studies, Standard Time (an Industrial Engineering term) is the time required for a person to complete a task or operation at a defined rate of working. It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may occur but have not been observed.

[edit] Method of calculation

The Standard Time is the product of three factors:

1. Observed Time - The time required to complete the task.
2. Rating Factor - The pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal. This factor is calculated by an Industrial Engineer trained to observe and determine the rating.
3. PFD Allowance - Personal, Fatigue, and Delay Allowances. These include factors such as: Are the workers standing all day? Are they working in a cold environment? Do they have to wear safety equipment?

The Standard Time can then be calculated by using:

Standard Time = (Observed Time)(Rating Factor)+(Observed Time)(Rating Factor)(PFD Allowance)
