ASSEMBLY LINE BALACEING (my activity)

 

BASIC TIME CALCULATION

SHIFT DURATION                            = 8 HRS 

WORKING HRS                                = 7HRS 
WORKING MINITUS PER DAY     = 420 min
 PRODUCTION TARGET                = 1000 UNITS  

PRODUCTION TARGET PE/ WEEK = 6000 UNITS

WORKING MINITUS PER WEEK = 420X 6          = 2520 min

 SEQUENTIAL DIAGRAM

 

 TASK TIME

 

TOTAL TASK TIME = ∑ (SUM OF ALL THE STATION CYCLE TIME)

TOTAL TASK TIME = ∑ (11.9 + 15.8 + 28.4 + 6.48........+ 120.6+184.6)

 

 TOTAL TASK TIME  = 881.98 SEC

 

 

CYCLE TIME REQUIRED = (PRODUCTION TIME PER DAY) / (UNIT REQUIRED PER DAY)

        = (420)/(100)

        = 4.2 MIN

  

NUMBER OF WORK STATION NEEDED = (TOTAL TASK TIME) / (CYCLE TIME)

= 881.98/42

= 20.9 ≈ 21 STATIONS  

 

LINE EFFICIENCY = (SUM OF TOTAL TASK TIME ) / (NO OF WORK STATIONS  X  60 SEC)  X 100

=(881.98)/(21*60)*100

=70%

BALANCED DELAY EFFIENCY = (100%  -  LINE EFFICIENCY)

 = 100% - 70%    = 30 %

(Not possible to achieve 100 efficiency)

 

LABOUR PRODUCTIVITY = (LABOUR WORKING HOURS     PER WEEK) / (UNIT PRODUCED PER WEEK) X100

=(42*60) / (6000)

 =42%
