In general Efficiency is the percentage of output to input ratio.
Output or Used Time
Efficiency = ------------------------------- X 100 %
Input or Available Time
Output x SMV
Sewing Efficiency = -------------------- X 100 %
Available Time
Output x SMV
= ----------------------------------------------- X 100 %
Total Used Man x Working Hr x 60
Note: SMV = Time required in min to complete 1 piece body.
