Question
Chapter 9, Problem 34AP
Summary Introduction
Interpretation: The sequence for the treatment of the patients for the minimization of the weighted value of the mean flow time is to be determined.
Concept Introduction:
Shortest processing time rule is used for the minimization of mean time flow of the project and hence it is used to minimize the time of mean flow of a process.
Tardiness is used to calculate the difference between the actual completion time and the required due date of the job. Any tardy jobs get completed after the due date of the job.

Consider the flow in Figure 7–1 but assume that no patients require follow-upappointments. All patients first check in with the single receptionist, which takesan average of 6 minutes. They are then seen by one of two nurses who take weight,blood pressure, etc., which takes an average of 10 minutes. Finally, they are seenby a GP in an examination room, which takes an average of 16 minutes. There arethree GPs. The table below summarizes this data. Assume the clinic has no waitingroom or examination room constraints.Assume that there are eight patients arriving an hour during working hours.Resource Minutes per patient Number of resourcesReceptionist 6 1Nurse 10 2Doctor 16 3a. What is the capacity of each resource?b. Which resource is the bottleneck and hence what is the capacity of the system?
Consider a workstation that has one maintenance mechanic to repair failed machines. We can think of the mechanic as the processor (scarce resource) and the machines awaiting repair as the jobs. Let us assume that
six machines are down, with estimated repair times given here, and that no new machines fail.

state whether or not each situation would be considered “compensable time” (and why or why not).
An employee of a fast food chain has to arrive at work 15 minutes early to change into the“mascot” costume and it typically takes another 15 minutes at the end of the shift to change outof the costume and properly store it. Due to the cost of the costume, employees are notallowed to take the costume home. The “mascots” typically work from 10am – 2pm, to coverthe lunch rush periods. How much time would be “compensable” for the mascots, assumingthe conditions/schedule listed above?2) George is a Radiology Technician at a local hospital and when on call, is required to be nofurther than 30 minutes away from the facility. Is the “on call” time, compensable?

- Fatema, Mariam, and Layan are three dental hygienists who work for Dr. Amnah at Family Dentistry. All three hygienists do pretty much the same thing every day. On an average, they see 12 people every day for regular teeth cleaning which involves cleaning, flossing, and normal checkup. Dr. Amnah, on the other hand, has quite unpredictable job. She has to respond to all types of teeth-related emergencies including having to do surgeries. All three hygienists always try to help each other out, have a very good attitude in general toward each other, and keep each other informed about matters that are relevant to them and to Dr. Amnah. Fatema specifically takes on the role of attending all community-related voluntary meetings and functions where Family Dentistry may have a stake or are asked for involvement.

The Traffic Police department is concerned with the increase in accidents on Sharah-e-Faisal.They are setting up a dedicated team to analyse the causes and propose a solution. Accidents can occur because of the sharp turns on road or unavailability of Pedistrian bridges. On the other hand, accidents can occur due to unsafe driving or human error. The observation was further breakdowned into 4 shifts to observe the impact of traffic flow, Morning (7:00am to 10:00am), Day (10:00am-3:00pm), Evening (3:00pm – 7:30pm) and Night (7:30pm – 7:00am). During the one month of observation, 150 minor and major accidents have occurred.
