Posh Nails Katie Posh runs an upscale nail salon. The service process includes five activities that are conducted in the sequence described below. (The time required for each activity is shown in parentheses): Activity 1: Welcome a guest. (1 minute)Activity 2: Clip and file nails. (3 minutes)Activity 3: Paint. (5 minutes)Activity 4: Dry. (10 minutes)Activity 5: Check out the customer. (4 minutes)Three servers (S1, S2, and S3) offer the services in a worker-paced line. The assignment of tasks to servers is the following: S1 does Activity 1. S2 does Activities 2 and 3. S3 does Activities 4 and 5. The drying process does not require server 3’s constant attention; she/he needs to only escort the customer to the salon’s drying chair (equipped with fans for drying). The time to do this is negligible. There exists only one drying chair in the salon. What is the average labor utilization of the servers (in decimal form)?

. In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.5 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, 2 hours waiting for the setupof the machine, 1 hour 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 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.5 hour waiting for the other pieces of the batch to go through welding, 0.5 minute at the welding machine, and 1 hour waiting for the transfer to the next department. Determine the exact flow time. What is the value-added percentage of the flow time?
