1. If patients arrive at an average rate of 4 patients per day, what is their mean inter-arrival time in days?
2. In this simulation, theoretical utilization of the intensive care unit (ICU) is calculated as the flow rate of patients that arrive for service at the ICU in a given unit of time divided by the ICU’s capacity to serve customers in that same unit of time. You can think about this as demand/capacity. What is the theoretical utilization of the ICU if the mean inter-arrival time is 4 hour(s), the mean length of stay is 6 hour(s), and there are 4 beds in the ICU?
