GSD = (Man power X Work hour) / Target

SMV = Basic time + (Basic time X Allowance)

Basic time = Observed time X Rating

Observed time = Total Cycle time / No of cycle

Rating = (Observed Rating X Standard rating) / Standard rating

Efficiency = (Earn minute X Available minute) X100

Earn minute = No of Pc’s (Production) X Garments SMV

Available minute = Work hour X Manpower

Organization Efficiency = (Basic pis time / Bottle neck time) X 100

Basic pis time = Total GMT SMV / Total Manpower

UCL = Basic pis time / Organization Efficiency

LCL = 2 X Basic pis time – UCL

Capacity = 60 / Capacity time in minute

Cycle Time = 60 / Team target

Capacity Achievable = Capacity X Balance

Daily output = Work hour / SMV

Factory capacity = (Work hour / SMV) X Total worker X Working day X Efficiency

CPM = (Total over head cost of the month / No of SMV earners X Work minutes) X Efficiency

Required no of operator = Target daily output / Daily output per operator

উদাহরন হিসাবে কিছু ম্যাথ দিয়ে দেওয়া হলঃ

1. Efficiency = Output/Input

= (SMV X Product Quantity) / (Worker X Working Hour X 60)

= [(38.50 X 700) / (60 X 10 X 60)] X 100
= 74% (Line Efficiency)

Here,
SMV=38.50
Working hour=10
No. of worker=60

2. Target/hour = (60/SMV) X Efficiency%
   = (60/0.85) X 70%
   = 50 pcs/hour
   Here,
   SMV=0.85
   Efficiency=70%
3. Target/line = [(No of worker X working hour X 60)/SMV] X Efficiency% = [(75 X 10 X 60)/23.5] X 60% = 1150 pcs Here,
   No of workers=75
   Working hours=10
   SMV=23.5
   Efficiency=60%
4. Required days for the schedule = Total order quantity/Average target = 50000/2000 =25 Here,
   Average target=2000
   Order quantity=50000
5. CM of garments= (Total Production)/(no of worker X work hour) = 250000/(1500 X 10) =1.66 BDT Here,
   Total Production=250000
   No of workers= 1500
6. Factory capacity = [(Work hour X total workers X working day X 60)/SMV] X Efficiency = [(10 X 1500 X 26 X 60)/14.13] X 55%
   = 828025 pcs/month
7. Line GSD/day = (Manpower X work hour)/target = (50 X 10 X 60)/900 = 33
