In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 14.35 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, 2 hours waiting for the setup of the machine, 1 hour waiting for the other pieces 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, 2 hour waiting for the setup of the welding machine, 0.35 hour waiting for the other pieces of the batch to go through welding, 0.25 minute at the welding machine, and 2 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

A small call center normally has four employees answering calls while open. On average, seven calls arrive every four minutes. Under normal operating conditions, each employee on average handles each call in 3.3 minutes.
