Experiment one, restaurant model

In a small canteen, the arrival of customers obeys an exponential distribution, and one customer arrives in an average of 1 minute. The restaurant is divided into a cold food department and a hot food department. The cold food department has 1 service window, the hot food department has 4 service windows, and the service time of the cold and hot food windows is exponentially distributed, with an average of 1 minute. Among them, 40% of customers choose cold food, and 60% of customers choose hot food. After the purchase, the customer looks for a seat, assuming that the customer can eat only after finding a seat and it takes 5-15 minutes for cold food and 15-25 minutes for hot food.

Try to build a model to determine the minimum number of seats required to make 95% of customers wait for a seat within 3 minutes. need to model a simulation program using simio and give out the final result
