CASE STUDY 11.2
1. 1 λ per 50 hours = 0.02 calls per hour 2. Mean service time = travel time + repair time = 1 + 1.5 = 2.5 hours m = 1 / 2.5 hours = 0.4 customers per hour 3. Travel time + the time spent in line =total customer waiting time. 1 + 1.6082 = 2.6082 hours

5. WITH ONE
When the customer base expands to 20 customers and company continues to use one technician, the average time in the waiting line will increase to 6.9454 hours. The average total waiting time will be 6.9454 + 1 = 7.9454 hours. The total cost will be $397.78 per hour. This average total waiting time is way too long and a second technician is definitely needed. The two service technicians provide the
