In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 13.6 hours. The time in the welding operation is spent as follows: 3 hours waiting in front of the cutting machine for the batch to start, 3 hours waiting for the setup of the machine, 1 hour waiting that the other pieces of the batch 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, 0.6 hours waiting that the other pieces of the batch go through cutting, 0.65 minutes at the welding machine, and 1 hour waiting 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? percent References eBook & Resources Worksheet Difficulty: 3 Hard PA 8-4 In the welding operations of a bicycle manufacturer... Learning Objective: 08-03 Determine the percentage of flow time that is value-added time. 14
Explanation / Answer
Flow time = (3hr + 3hr + 1hr + 3hr + 1hr + 1hr + 0.6hr +1hr)*60 + 2.65min
= 13.6*60 + 2.65
= 818.65 min
Value added time = 2min+ 0.65 min = 2.65min
Value percentage of flow time= 2.65/818.65= 0.00323 =0.323%
