Question

Christmas Express makes wreaths in batch sizes of 12. The cutting & assembly process takes 8 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. Compute the value-added, non-value-added, and the total lead time of the wreath process. Value-added lead time Non-value-added lead time: Move time Within batch wait time Total lead time Compute the value-added ratio. Round to one decimal place. percentage

Explanation / Answer

There are no details as to "Within Batch Wait Time" which should have been there (such as The cutting and assembly process are done at the same time, but only one wreath can be decorated at a time).

Therefore, I have answered on the basis of information provided in the question, whereby, "Within Batch Wait Time" will be 0.

__________

Part A)

The table is completed as follows:

__________

Part B)

The formula for calculating value added ratio is given below:

Value Added Ratio = Total Value-Added Lead Time/Total Lead Time*100

Using the values calculated above, we get,

Value Added Ratio = 18/228*100 = 7.89%

Remarks Value-Added Lead Time (8 + 10) 18 Time Taken for Cutting and Assembly + Time Taken for Decoration Non-Value-Added Lead Time Move Time 12 Movement Time Within Batch Wait Time (18*(12-1)) 198 No Information Provided in the Question Total Lead Time 228 minutes
