# How to calculate Capacity, Target with Target Efficiency ?

Today we are going to discuss the garments production line Capacity, target and target efficiency. I am going to show how to relate the efficiency with the target and capacity. Here we realize with a garment industry efficiency, productivity, formula & calculation with easy examples. Let’s start about the calculation of line, individual and factory capacity and target.

**Before start has good to conjecture SMV, Output, Manpower, etc. So suppose, the product of the Lean line SMV=22, Manpower=45, and yesterday Output=750.**(SMV=Observed time X Rating +Allownce%. )

**1. Capacity**

### Inline production Capacity

** **

SMV=22, Manpower=45 and working Hour= 10, what is the capacity?

Working hour X Manpower

————————————-

SMV

10(Hrs) X 60(Mins) X 45 (Man)

= —————————————-

20 (Mins)

= 1080 pcs. Per Day

### Individual Production Capacity

Suppose the operator works Inseam Join. His/her present SMV 51 cm. What is the capacity per hour?

60 Mins

—————–

Present SMV

60

= ————

.51

= 118 pcs.

So, the Operator is able to Join Inseam 118 Pcs. per hour.

## Calculation Capacity, Target formula

Factory Capacity

In this case, if different SMV among the different lines, SMV will be average all lines of the factory.

At first, we have to know,

Factory’s Total Capacity in Hour

To calculate the factory’s total capacity in pieces, first, we have to know Factory’s Total Capacity in Hour. The formula is very simple but dynamic.

Total Lines X Machines in a line X Daily Working Hour = Factory’s

Total Capacity in

Total Capacity in

Here,

Total Lines is 36

Machines in a line 35

Working Hour 10

As above,

Factory’s Total = 36×35×10 hours = 12600 hours

Factory’s Total = 36×35×10 hours = 12600 hours

** **

Factory’s Total Capacity in pieces =

[(Factory’s Total Capacity in Hour × 60/SAM of Product × Average Line Efficiency)× 3 Months

average Efficiency

SAM of Product × Average Line Efficiency

12600 × 60/SAM of Product × Average Line EfficiencyX3 Months

2. Target

Individual Target efficiency

—– X wanted efficiency

SMV

=——– X 80%

.51

=117 X 80 % (Here, 117 is capacity)

=94 pcs (per hour Target)

**To achieve the target efficiency level 70% need the operator 82 pcs the inseam join.**

**Line Target efficiency**

Working Hour X Manpower

————————————– X wanted efficiency

SMV

10 X 60 X 45

= ——————- X 80%

22

=1227 X 80 % (Here, 1227 is directly observed capacity)

=982 pcs in a day

** **

*To achieve the target efficiency level of 70% in a day, need *

*p*__r__oduces 859 pcs from the Line.

__r__oduces 859 pcs from the Line.

So, Target Efficiency = 70%

** **

Factory Target efficiency

In this case, if different SMV among the different lines, SMV will be average all lines of the factory.

Suppose to,

Total Lines = 26

Average SMV of the factory is 25.00

Manpower = 23 X 45 = 1,035

Working Hour X Total Manpower

——————————————- X wanted efficiency

Average SMV

621000

= ——————- X 80%

.25

=24840 X 80 % (Here, 24,080 is capacity)

=19,872 pcs in a day from whole factory Sewing Lines.

To achieve target efficiency level 80% in a day need

output 19,872 pcs from the Line.

output 19,872 pcs from the Line.
