Question - Flu Shot: Suppose that School of Business Administration is considering offering the students the opportunity to get a flu vaccine ('flu shot'). The school is considering setting up the operation for just one day during the lunch hour. For a preliminary analysis, consider the following simplified description of the proposed operation: a total of 600 students will arrive at the cafeteria during the 12:00 Noon to 1:00 PM lunch hour. The students will arrive uniformly over time with no variability. No student will show up either before or after the lunch hour. Since 20% of the students have never had a flu shot, they first must go to a nurse practitioner for a quick review of their medical history. After this review, they then join a line waiting for vaccination by a doctor. The remaining 80% go straight to the line waiting for vaccination. (It is assumed that all the students will receive the vaccine.) There are 3 nurse practitioners available to review medical histories. Each nurse practitioner can review a student's medical history in 2 minutes. There are 4 doctors giving the vaccinations. It takes only 30 seconds for a doctor to vaccinate a student.
To help your analysis, please draw a process flow diagram for this operation. Indicate the capacities and rates of student flow (in number of students per minute) during the lunch hour.
Process Flow Diagram:
1. How many students will come every minute during lunch hour (this is the arrival rate)?
2. How many students can be handled every minute by the medical history review station of three nurse practitioners (this is the capacity rate of review station)?
3. How many students can be handled every minute at the vaccination station of four doctors (this is the capacity rate of the vaccination station)?
4. What is the maximum build-up of students at the nurse-practitioner review?
5. What is the longest waiting time at the nurse-practitioner review station?
6. At what time will the line at the review station be empty?
7. At what time will the vaccination line be empty? (Draw an inventory built-up diagram to facilitate your analysis.)
