Question

In the welding operations of a bicycle manufacturer... In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.3 hours. The time in the weiding operation is spent as follows: 1 hours walting in front of the cutting machine for the batch to start, 2 hours waiting for the setup of the machine, 1 . hour waiting for the other pleces of the batch to go through cutting. 2 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.3 hour walting for the other pieces of the batch to go through welding. 0.7 minute at the welding machine, and 2 hour wailing for the transfer to the next department. (Round your percentage answer to 4 decimal places.) Determine the exact flow time. What is the value-added percentage of the flow time in _________ percent.

Answer 1

The exact flow time of the bike frame in the welding operations is 11.3 hours. The value-added percentage of the flow time is 0.3979%.

Step-by-step explanation:

The exact flow time of the bike frame in the welding operations can be calculated by summing up the time spent at each step. According to the information provided, the flow time is as follows:

1. 1 hour waiting in front of the cutting machine for the batch to start.
2. 2 hours waiting for the setup of the machine.
3. 1.5 hours waiting for the other pieces of the batch to go through cutting.
4. 2 minutes at the cutting machine.
5. 3 hours waiting for the transfer to the welding machine.
6. 1 hour waiting in front of the welding machine for the batch to start.
7. 1 hour waiting for the setup of the welding machine.
8. 0.3 hour waiting for the other pieces of the batch to go through welding.
9. 0.7 minutes at the welding machine.
10. 2 hours waiting for the transfer to the next department.

Adding up these times, the exact flow time of the bike frame is 11.3 hours.

The value-added time is the time spent performing the actual welding operation. In this case, it includes the 2-minute cutting time and the 0.7-minute welding time. The value-added time is 2 minutes + 0.7 minutes = 2.7 minutes.

To calculate the value-added percentage, divide the value-added time by the flow time and multiply by 100. In this case, the value-added percentage is (2.7 minutes / 678 minutes) * 100 = 0.3979%
