Question

In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.75 hours. The time in the welding operation is spent as follows: 2 hours waiting in front of the cutting machine for the batch to start, 1 hours waiting for the setup of the machine, 2 hour waiting that the other pieces of the batch go through cutting, 2 minute at the cutting machine, and 2 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, 2 hour waiting for the setup of the welding machine, 0.75 hours waiting that the other pieces of the batch go through cutting, 0.35 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

Answer 1

Exact flow time = 14.5 hours

Value added percentage of flow time = 0.0020

Step-by-step explanation:

Exact Flow time is calculated as :

1 + 2+ 2+ 3+ 2+ 2+ 05+ 2 hours + [1.75 minutes / 60] hours = 14.50 hours

14.50 * 60 = 871.75 minutes

Value added percentage of flow time calculations :

1.75 minutes / 871.75 minutes = 0.0020 or 0.2%
