The formula used for calculating available capacity of the sewing line has been given below. The available capacity of a line is presented in minutes or hours.
Sewing room Capacity per Day= {(No. of machine x daily work hours x 60) – absenteeism %} x Efficiency % (unit in minutes)
Monthly Capacity = Daily Capacity X No. of working days in a month
The capacity of a line depends on the average efficiency% of the line and operator absenteeism%. First line wise capacity is calculated and then added all line's capacity to calculate available capacity of the floor.
For example: A factory floor has 5 lines. Factory works for 8 hours day. No of total operators, line efficiency and absenteeism percentage are as given in the following table.
