Chapter 5, Problem 18P
To meet holiday demand, Penny’s Pie Shop requires a production line that is capable of producing 50 pecan pies per week, while operating only 40 hours per week. There are only four steps required to produce a single pecan pie with respective processing times of 5 minutes, 5 minutes, 45 minutes, and 15 minutes.
- What should be the line’s cycle time?
- What is the smallest number of workstations Penny could hope for in designing the line considering this cycle time?
- Suppose that Penny finds a solution that requires only four stations. What would be the efficiency of this line?

Explain why doubling the capacity of a bottleneck may not double the system capacity?
Use a diagram to explain the concept of Throughput time and Bottleneck.
Mr. K’s is a very popular hair salon. It offers high-quality hair styling and physical relaxation services at a reasonable price, so it always has unlimited demand. The service process includes five activities that are conducted in the sequence described below. (The time required for each activity is shown in parenthesis):
Activity 1: Welcome a guest and offer homemade herb tea. (10 minutes)
Activity 2: Wash and condition hair. (10 minutes)
Activity 3: Neck, shoulder, and back stress release massage. (10 minutes)
Activity 4: Design the hairstyle and do the hair. (25 minutes)
Activity 5: Check out the guest. (5 minutes)
Three servers (S1, S2, and S3) offer the services in a worker-paced line. The assignment of tasks to servers is the following:

- Positively Rivet Inc. is a small machine shop that produces sheet metal products. It had one line dedicated to the manufacture of light-duty vent hood shells, but because of strong demand it recently added a second line. The new line makes use of higher-capacity automated equipment but consists of the same basic four processes as the old line. In addition, the new line makes use of one machine per workstation, while the old line has parallel machines at the workstations. The processes, along with their machine rates, number of machines per station, and average times for a lone job to go through a station (i.e., not including queue time), are given for each line in the following table: Process Old Line New Line Rate per Machine (parts/hour) # Machines per Station Time (minute) Rate per Machine (parts/hour) # Machines per Station Time (minute) Punching 15 4 4.0 120 1 0.50 Braking 12 4 5.0 120 1 0.50 Assembly 20 2 3.0 125…arrow_forwardMr. Aris Benn manages an assembly line that produces a piece of equipment that is used to clean floors.
