যারা IE এবং Planning বিভাগে ক্যারিয়ার গড়তে চান তাদের জন্য প্রযোজ্য ।

1) Preparing balance layout.

2) SMV calculation.

3) Efficiency calculation.

4) Line balancing.

5) Time study for line balancing.

6) Taking skill test for recruiting operators and Fix-Up salary.

7) Proper utilization of worker co-operator.

8) Operator train-up.

9) Preparing skill matrix.

10) Incentive system implementation

11) Problem identification and solution.

12) Alter reduction.

13) Non productive time (NPT) elocution and management.

14) Operator motivation and Floor control.

15) Man machine report preparing.

16) Wastage deification and reduce.

17) Reduce excess motion and improve new method.

18) Daily input output check.

19) Line setup-time reduces and line planning.

20) Build -up communication with other Department for increasing production.

21) Target set up line and floor.

22) Line efficiency (%).

23) Arrange meeting with production team or management.

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
