Christmas Express makes wreaths in batch sizes of 14. The cutting & assembly process takes 6 minutes per wreath and the decorating process time is 10 minutes per wreath. It takes 12 minutes to move the wreaths from the cutting & assembly process to the decorating process. What is the total lead time of the wreath process?

Group of answer choices

236 minutes

28 minutes

16 minutes

228 minutes

 

Total lead time = 16+12+208 =236 minutes

Value-Added Lead Time = Time Taken for Cutting and Assembly + Time Taken for Decoration

=(6 + 10)=16      

Non-Value-Added Lead Time                    

Move Time        =12        

Within Batch Wait Time (16*(14-1))        =208     

Total Lead Time =16+12+208     236minutes     

Step-by-step explanation

The value added Leadtime = 16 minutes (cutting and assembly + decorating process time)

Non-value added lead time :

Move time = 12 minutes

within batch wait time = ( total time to perform operations) X ( batch size - 1)

within batch wait time = ( 6 + 10) * ( 14-1)

within batch wait time = 208 minutes

Total lead time = 16+12+208  =236 minutes

The Value added ratio = Value added lead time / Total lead time

Value added ratio = 16 / 236

Value added ratio = 6.78%
