Calculate S.M.V for a Garment
Following formula very important to start solve a problem
//////////////////////////////////////////////////////////////////////////////////////
////////////////////
Basic time= (Observed Rating * Observed Time)/Standard Rating
Standard Rating considered as 100%
S.M.V= Basic time + All Allowance
//////////////////////////////////////////////////////////////////////////////////////
///////////////////
Now I hope to explain this method using suitable question.
No Element Observed
Rating
Observed
Time
(Min)
Occurrence
1 Pick up and sort bundle 95 0.18 1/10
2 Align first sleeve to opening 100 0.08 1/1
3 Overlock and attach first sleeve head 90 1.12 1/1
4 Re-position 95 0.03 1/1
5 Align second sleeve 90 0.09 1/1
6 Overlock attached sleeves 100 1.1 1/1
7 Aside garment 110 0.06 1/1
8 Close bundle and complete ticket 90 0.60 1/10
Relaxation allowance =15%
Machine attention allowance=10%
( (a) Calculate the standard minute value for one garment.
( (b) If the average line efficiency is 90%, how many garments would be expected to complete
in this line within an 8 hours working shift?
OK! Now I Hope To Solve This Question One By One…
(a)
First we must find basic time per cycle
Example No:1
= [(95*0.18)/100]*(1/10)
= 0.0171](https://image.slidesharecdn.com/smv-cal-160216101615/85/calculate-standard-minute-value-for-a-garment-1-320.jpg)
![Example No:2
= [(100*0.8)/100]*(1/1)
You can repeat it until No 8
After Count total value of basic time per cycle.
=2.4346
And, count machine operation join basic time per cycle. (Here it can be taken No3and No6)
=2.108
Now you can add machine attention allowance
=2.108*10/100
=0.2108
Add total basic time per cycle
=0.2108 + 2.4346
=2.6454
Add relaxation allowances
=2.6454*15/100
=0.39681
S.M.V = Basic Time + All Allowance
=2.6454 + 0.39681
=3.04221
S.M.V = 3.04
(b)
Number of garments = Time Duration/S.M.V
= (1*60*8)/3.04221
=157.780
This value is 100% efficiency. But we need 90% efficiency output value
=[(157.780)/100]*90
=142.0020
Garments =142
