An administrator in a small suburban hospital is concerned with the waiting lines in the emergency room, which is always staffed by at least one doctor. Patients arrive on average at the rate of 14 per hour. THey are served on a first-come, first-served, basis. On average, one doctor, working alone, can treat a patient in 5 minutes. For each additional doctor added, 2 more patients can be seen in a hour by all doctors working together, on average. (Assume the Poisson arrivals and exponential service times) The adminstrator has set the objective that, on average, there should not be more than 6 patients waiting to see a doctor. 1. What is the minimum number of doctors needed to meet the administrator's objective? (with the minimum number of doctors working all together)
describe the situation if a single doctor is working?
what is the appropriate operating characteristicsfor this problem?
what is the minimun number of doctor needed to meet the administrator's objective?
what is the probability that the ER room is empty?
how long does a patient has to wait to be seen by a doctor?
on average, how many patients are in the waiting room?
how many patients can be seen in 8 hours work day?
what is the chanc that a patient wont have to wait for service?
