The most common question is how do we plan and calculate capacity when the company does multi style products?
The answer is - a factory capacity should be planned in a manner that it is independent of styling.
Hence production capacities for all styles have to be converted into a common unit of measurement, which is TIME.
The following parameters have to be calculated to ascertain the factory production capacity.
-
SMV for a garment - Standard Allowed Minutes for a garment
-
Factory efficiency Levels
A 200 machine factory employs 250 workers. Factory works 26 days in a month and 8 hours a shift.
