SMV calculation of a 5 Pocket Denim jeans pant: 

Problem: From the above table, we find total cycle time is 15.73 minute, suppose the performance rating of all operator is 80% for Denim jeans pant. Now, Find out the SMV for that Denim jeans pant. 

Solution: 

We know,

SMV = Basic time + Allowance

          = (Cycle time × Rating) + (Bundle allowances + machine and personal allowances)

          = (15.73× 0.80) + (Bundle allowances + machine and personal allowances)

          = 12.30 + ( 12.30 × 10%)+ (12.30× 20%)

          = 12.30+ 1.23 + 2.46

          = 15.99

So, we find out SMV for that Denim jeans pant is 15.99 minute.

Production target calculation of a Denim jeans pant:

Problem: We find SMV for that 5 Pocket Denim jeans pant is 15.99 minute. Suppose, No. of worker of that line is 64, the efficiency of that line 80%.  Find out the production target per day of that 5 Pocket Denim jeans pant in one sewing line.

Solution: 

Here,

SMV = 15.99 Minute.

No. of worker = 64.

Line efficiency = 80% = 0.80

We know, Total working hour in a day = 8 hr.

Now, 

Production Target = {(Total manpower per line × Total working min per day )/ S.M.V.} × Efficiency

                                  = { (64 × 8 × 60) / 15.99 } × 0.80

                                  = 1536.96~ 1537

                                  = 1537 pieces.

So, Daily production target = 1537 pieces in one sewing line

and Hourly production target = 1537 / 8

                                                       = 192.125~ 192 pieces / hr.
                                                       = 192 Pieces/hr in one sewing line.
