Question
consider a clinic that serves two types of patients “A” and “B”. The clinic has excessive demand for its services (i.e., the number of potential patients exceed the capacity of the clinic). For both types of patients, each one requires a screening service through Nurse A and a finishing checkup at Nurse C. These activities are done using shared resources that can each serve a single patient at a time. The intermediate service step is done by dedicated doctors (Doctor A and Doctor B, respectively) and nurse B. Both doctors can process only one patient at a time. Capacities are provided on the chart below.
A. Doctor A and Doctor B only.
B. Doctor A and Nurse C only.
C. Doctor A only.
D. Nurse C only.
E. All (Nurse A, Nurse B, Nurse C, Doctor A, and Doctor B) are bottlenecks.
Patient A Doctor A 6 patients/day Patient A Patient A Nurse A 2 patients/day Nurse C 9 patients/day Patient B Patient B Nurse B Doctor B Patient B 8 patients/day 5 patients/dayExplanation / Answer
The answer is given below:
D. Nurse C only.
The bottleneck in the system above is Nurse C only, because there is increased traffic as where the patients from doctor A and the patients from doctor B visit the Nurse C, so the process would slow down with Nurse C only.
