The local hospital’s emergency department has 6 trauma bays. On average, patients requiring a trauma bay arrive at the rate of 1 every 30 minutes. The coefficient of variation of inter-arrival time is 1. If the hospital has an available trauma bay, it is immediately allocated to a needy patient. If there are no trauma bays available, the patient is sent to another hospital. On average, a patient’s length of stay in a trauma bay is 1.5 hours (with a standard deviation of 1.5 hours).
