QUESTION 22 (10 points) Value Added Percentage (VAP) A bike frame has to go through the welding operation. The time in the welding operation is spent as follows: 3 hours waiting in front of the cutting machine for the batch to start, 1 hour waiting for the setup of the machine, 3 hours waiting for the other pieces of the batch to go through cutting, 1 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine; then, at the welding machine, the unit spends 2 hours waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 2 hours waiting for the other pieces of the batch to go through welding, 0.25 minute at the welding machine, and 2 hours waiting for the transfer to the next department. (a)[6] Calculate the exact total flow time in minutes of the welding operation (b)[2] Calculate the exact value added time in minutes of the welding operation. (c)[2] Calculate the value added percentage (percentage, 5 decimals, ie. 1.54397%).

Explanation / Answer

(a)

Waiting at cutting = 3+1+3 = 7 hrs.
Wait for transportation to welding = 3 hrs.
Waiting at welding = 2+1+2 = 5 hrs.
Waiting for transfer = 2 hrs.
Processing time = 1+0.25 = 1.25 min

Total flow time = (7+3+5+2) x 60 + 1.25 = 1021.25 min

(b)

Value added time = processing time = 1.25 min

(c)

% value added time = 1.25 / 1021.25 = 0.12240%
