Develop and analyze a simulation model for Koehler Vision Associates (KVA) in Problem 13 of Chapter 11 with the following assumptions. Assume that the de-mand is uniform between 110 and 160 per week and that anywhere between 10% and 20% of prospective patients fail to show up or cancel their exam at the last minute. Determine the distribution of net profit (revenue less overbooking costs) and number over-booked for scheduling 133, 140, or 150 patients.
