Assembly line balancing is important things of manufacturing system . its ultimate aim of the equal sharing of process in all work stations.We have use various calculus.
various steps involved in the assembly line balancing :
- Sequential Diagram
- Cycle time for each work station.
- Calculate the number of work stations needed
- Assigning task of all work stations with equal cycle time
- Find idle time
- calculate the Balance delay
- Line efficiency
Above steps very important to make assembly line balancing in processes Engineering.
process time precedence
A = 20
B = 10
C = 40 AB
D = 30 A
E = 80 D
F = 50 C
G = 70 C
H = 60 F
Production time per day
8hrs X 60min X 60sec = 28,800 sec
Target per day = 200 unit required
Cycle time =production time per day / target per day =28800 / 200 = 144 sec.
No of station required = 360/144 =2.5(round) = 3 stations.
Work Stations Process Task time Station time Idle time
I A+B+C+D 20+10+40+30 100 144 - 100 = 44 sec
II E+F 80+50 130 144 - 130 =14sec
