Question: What should be the Production in Pcs/Machine for a formal trouser & formal shirt? ... asked by Naushad
Productivity Benchmark of Shirt and Trouser
However, for your knowledge, formal shirt productivity figure is 9.12 units/ machine per 8 hours shift day (National benchmark, India) and 20.87 units/ machine per 8 hours shift day international benchmark (Hong Kong).For trousers, national and international figures are 6.84 units/shift and 19.25 units/ shift respectively (ICRIER, 1993). Average machine productivity on base technology is 8.07 units per shift (Indian factories). (Source: Managing productivity in the apparel industry, Bheda, 2008)

Calculating Production per Machine
If you are looking for estimated productivity figure of your factory then you can determine it by measuring garment SAM and line efficiency. Derive machine productivity by using the following formula:Formula#1:
Estimated Machine productivity = (Total minutes in a shift * line efficiency / Garment SAM)Assuming the SAM of a formal shirt is 20 minutes and the production line performs at 60% efficiency, the machine productivity would be
= 480 * 360%/20 = 14.4 units per 8 hours
Formula #2:
Machine productivity = (Total units produced by the line in shift ours/No. of machines used in making those garments).Assuming that one line of 20 machines produced 400 Polo shirts in 8 hours shift day.
Therefore, machine productivity of this production line would be = 400/20 = 20 pieces per machine per 8 hours shift.
what is meant by "unit" here? As an I E we calculate in pcs normally. So why unit is used here. Please explain
ReplyDeleteHi Nurul, Here 'unit' is used in place of 'piece'. It is garment quantity.
