The following problem is based on the limited queue and limited source models in the Limited Queue Template.xlsm and Limited Source Template.xlsm files. A service facility consists of one server who can serve an average of two customers per hour [service times are exponential]. An average of three customers per hour arrive at the facility (interarrival times are assumed to be exponential). The system capacity is three customers: two waiting and one being served. a. On average, how many potential customers enter the system each hour? If needed, round your answer to one decimal digit. 1.7 9 b. What is the probability that the server is busy at a typical point in time? If needed, round your answer to a whole percentage. 58 0 %
