Refer to Exercise 3.5. Once the triage system is put in place, it performs quite close to expectations. All data conform to planners’ expectations except for one set— the classifications made by the nurse practitioner. Assume that the triage nurse has been sending 91 percent of all patients to the Simple Prescription area when in fact only 90 percent should have been so classified. The remaining 1 percent is discovered when transferred to the emergency area by a doctor. Assume all other information from Exercise 3.5 to be valid. On average, how long does a patient spend in the ER? On average, how long does a Potential Admit spend in the ER? On average, how many patients are in the ER? Assume the process to be stable; that is, average inflow rate equals average outflow rate.
