Consider the departure area of an international airport system. The interarrival-time distribution for passengers is EXPO(3) minutes; and the first arrival is at time 0. Suppose that there are 2 different managers (Manager1, Manager2) who can handle two types of emergency situations. First type situation: Related to the passport control. There is a single officer who controls the passports. Checking each passport takes UNIF(2,4) minutes. After the completion of the passport control process, the officer may realize a serious problem with probability 0.1. If the officer realizes a serious problem, one of the randomly selected managers is requested to provide "Service 1" to the passenger. Otherwise, the passenger leaves the system. Note that Service 1 involves checking the documents of the passenger and taking the passenger to the document verification officer. This requires TRIA(4, 6, 8) minutes. Note that the manager is released once the passenger is taken to the only document verification officer in the airport. Document verification process takes EXPO (3) minutes. If a passenger's document is found clear by the verification officer (which occurs with probability 0.8), the same manager who provided "Service 1"is requested again to provide "Service 2". This process involves taking the passenger to the customs check area taking UNIF(2,4) minutes. If the passenger's document is not found clear, then the passenger leaves the system. Second type situation: Related to the customs check. The customs officer handles the screening process which requires UNIF(5, 9) minutes. Note that there is a single customs officer in the airport. After the completion of this process, if there appears to be something suspicious about a passenger (which occurs with probability 0.09), any one of the managers is randomly requested to provide "Service 3" to the passenger. Otherwise, the passenger leaves the system immediately. Service 3 involves checking the luggage and deciding how to proceed. This takes TRIA(10, 14, 18) minutes. After Service 3, the passenger is taken out of the system, and the manager she seized is also released. Suppose that the passengers with a "first type situation" have higher priority than the passengers with a "second type situation" (In other words, Services 1 and 2 have higher priority than Service 3). When an emergency situation of first type occurs, a number indicating the level of emergency (Emergency Level) is assigned. A passenger is assigned level 1 with probability 0.2, level 2 with Fall 2023 probability 0.5, and level 3 with probability 0.3. Within the group of passengers with a "first type situation", those with a higher Emergency Level have a higher priority to seize a manager. Within the group of passengers waiting to get "service 3" LIFO (last in first out) discipline is used while allocating a manager. Any unspecified queue discipline can be considered as FIFO. Next, consider the following hint. Note that services 1 and 2 have the same priority level. This urges you to benefit from the concept of "shared queue" at least while modeling the processes for service 1 and service 2. Otherwise, if you create two separate queues using two Process modules (with the same priority value), ARENA automatically applies FIFO rule to break the tie while allocating the managers to passengers. However, as mentioned, entities with higher Emergency Level should be favored if a "first type situation occurs". Therefore, you need a single queue where the passengers with a "first type situation" will be placed regardless of where their seize activities are within the model. Considering the above hint, model the above system. Run the model for 16 hours. Report the following: -Average amount of time the passengers wait for a manager for the first type of emergency situation (in minutes) -Average utilization of manager 1
