Christmas Express makes wreaths in batch sizes of 30. The cutting and assembly process takes 3 minutes per wreath, and the decorating process time is 9 minutes per wreath. It takes 4 minutes to move the wreaths from the cutting and assembly process to the decorating process. a. Compute the value-added, non-value-added, and total lead times of the wreath process.

Respuesta :

Answer and Explanation:

The computation is shown below:

The Value added lead time is

= (cutting & assembly + decorating process time)

= 3 minutes + 9 minutes

= 12 minutes

For  Non-value added lead time :

Move time = 4 minutes

Now  

within batch wait time = value added time × ( batch size - 1)

= (3 + 9) × ( 12 - 1)

= 132 minutes

So,  

Total lead time = 144 minutes
