Dental Hygienist | 58 | 0 | 23.2 | 0.043 | 1 | 2 | 0.086 |
Dental Technician | 0 | 40 | 24.0 | 0.042 | 1 | 1 | 0.042 |
Dentist | 5 | 25 | 17.0 | 0.059 | 1 | 1 | 0.059 |
Calculations
(a)
Note that the capacity of the Dental Technician pool is the lowest and hence this is the bottleneck resource.
(b)
Flow rate is 2 patients per hr. = 0.0333 patients per minute
So, utilization of the dentists = 0.033 / 0.059 = 56.67%
