Operation Breakdown of a Girls Swim-wear with SMV and Production Target

Introduction: Girls swimwear is a kind of dress designed for girls especially worn to water-based activities such as swimming, diving, also sunbathing. This swimwear is known as various names in various locations. It is known as a swimsuit, swim costume, bathing costume, etc. There are also some different styles like one-piece swimwear, Bikini swimwear, Tanki and many more.

In this article, we learn Operation Breakdown of Swimwear with SMV and Production Target.

1. Front part. 
2. Front Gusset
3. Back Part.
4. Back Gusset.
5. Back Yoke 
6. Neck
7. Body part.
8. Leg open.

Operation Breakdown of a Girls Swimwear: Operation Breakdown of a Girls  Swimwear is done by the following table;

SL. No.	Name of Operation	Cycle Time	Calculated Production at 100%
1	Match All Cut parts	0.23	260
2	Attach Front Gusset to Front Part	0.23	260
3	Attach Back Inner & Outer Gusset to Back Part	0.27	222
4	Attach Bake Yoke to Back	0.16	375
5	Stay Stitch to Both Side	0.23	260
6	Make Care Label (5 Label Together)	0.3	200
7	Tack Label with Fabric & Fabric with Body	0.49	122
8	Join Shoulder	0.27	222
9	Join Side Seam	0.50	120
10	Attach Elastic to Neck, Armhole, & Leg	0.999	60
11	Top Stitch & Trim Excess Thread at Neck, Armhole, & Leg	1.75	34
12	Bartack to Neck, Armhole, & Leg	0.58	103
13	Remove Sticker & Final Thread Cut	0.30	200
	Total Cycle Time	6.308

Table - 1: Operation Breakdown of a Girls Swimwear.

From the above table, we get operation breakdown and total cycle time. We also estimate each operation production target which helps us line balancing and preparing machine layout.

SMV calculation of a Girls Swimwear: 

Problem: From the above table, we find total cycle time is 6.308 minutes, suppose the performance rating of all operators is 85% for Swimwear. Now, Find out the SMV for that Swimwear. 

Solution: 

We know,

SMV = Basic time + Allowance

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

          = (6.308× 0.85) + (Bundle allowances + machine and personal allowances)

          = 5.36 + ( 6.308 × 10%)+ (6.308× 20%)

          = 5.36 + 0.630 + 1.26

          = 7.25

So, we find out SMV for that Swimwear is 7.25 minutes.

Production target calculation of a Girls Swimwear:

Problem: We find SMV for that Swimwear is 7.25 minutes. Suppose, No. of workers of that line is 22, the efficiency of that line 80%.  Find out the production target per day of that Swimwear in one sewing line.

Solution: 

Here,

SMV = 7.25 Minute.

No. of worker = 22.

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

                                  = { (22 × 8 × 60) / 7.25 } × 0.80

                                  = 1165.24~ 1165

                                  = 1165 pieces.

So, Daily production target = 1165 pieces in one sewing line

and Hourly production target = 1165 / 8

                                                       = 145.625 pieces / hr.
                                                       = 145 Pieces/hr in one sewing line.

So, From this post, we learn about Operation Breakdown of a Girls Swimwear, Total Cycle Time, SMV calculation, and Production target in daily and hourly.
