2. Problem 3.6

3. Macro: Average number of patients in the system = 20+1. 8+5+2. 8+1+2
Average flow time = 52.6/(55/60) = 57.3

4. Re-Check
Micro Method
Common =
= 32.3
TSP= = 55.3
TPA1= = 73.2 ……(4.95 PA patients out of 5.5 PA patient: 90%)
TPA2= =96.2 (0.55 PA patients out of 5.5 PA patient: 10%)
TPA = 73.2(.9) (.1) =75.5
TSP= is 90% of flow units, and TPA =75.5 is for 10% of flow units
T = 55.3 (.9) (.1) = 57.32
Re-Check again
T= 55.3 (49.5/55) (4.95/55) (.55/55)
T= (re-check)
