Q1 Diner by Coffee Break Queue Problem Consider the flow of customers through Diner by Coffee Break Suppose that two different types of customers arrive at Diner: set menu customers and a la carte customers. There are two separate areas for getting food: set menu area and a la carte area. Assume that each area has its own Independent queue le alla la carte customers wait in the same geve) Both queves operate according to FIFO (first-in first-out) discipline. Only one customer can get food at a particular time in a particular area (e. an a la carte customer needs to wait for the preceding customer to get done in the a la carte area before she gets her food). After the customers get their food, they move to one of the two payment lines. A customer can join any of the lines (queues). However, they always prefer the one with lower number of customers in it. If there is a tie, then they randomly choose a line. There are two cashiers at the end of the first payment line. A customer in this line can be served by any one of the available cashiers. On the other hand, there exists a single cashier at the end of the second line. The system is empty and the resources are idle at time o. Customer 1 (the first set menu customer arrives at time o. Customer S (the first a la carte customer) arrives at times. The following table shows the interarrival and service times in seconds). For example, the time between the arrivals of Customer 1 and Customer 2 (the first and second set menu customers) is 20 seconds. The time between the arrivals of Customer S and Customer 6 (the first and second la carte customers) is 15 seconds.
