IE এর বেসিক ফর্মূলা 

#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 pitch 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
