Question 1 Airport Terminal bowl model (25 points innate) fictitious character I BASE MODEL (10 points) Management penurys to contract Terminal 1 at a hub airport with an eventual marrow toward improvement. The first step is to model it as it is (i. e. , BASE model) during the eight hours of the busiest part of a typical weekday. You will create an bowling ball model of the sign in and the certificate operations, only. Once passengers get through security department they are on their way to their departure gate and leave the system.Passengers arrive one at a fourth dimension through the front entrance from curbside ground pane with i nterarrival propagation distributed Expo(0. 5) legal proceeding. All time units are in minutes. Of these arriving passengers, 33% go left hand to an old-fashioned manual check-in counter. And, 57% of the arriving passengers go right to a new automated check-in counter. These two types of passengers take no time to move from the front entrance to their check-in locations. The remaining 10% of arriving passengers do not need to check in at all and go directly from the front entrance to security.It takes these passengers Unif(3, 5) to move from the front entrance to security. on that point are two agents at the manual check-in station, fed by a single first-come-first-serve(predicate)r queue. Manual check-in service times are Triangular(1, 2, 5). After manual check-in, it takes passengers Unif(2. 5, 6. 5) to walk to the security area. The automated check-in consists of two kiosks and is fed by a single first-come-first-server queue. Automated check-in times are Triangular(0. 5, 1, 1. 5). After checking in, these automated check-in passengers take Unif(1, 3) to walk to the security area.Notice that all types of passengers eventually go to the security area where there are 6 check-in pods fed by a single first-come-first-serve queue. Security check-in times are Triangular(1, 2, 6). This time covers the many security activities in a pod like x-ray, metal detector, bag search, etcetera Once through security, passengers head to their gates and leave the model. Simulate this system for 8 hours and 1 replication. The performance metric of interest is the number total time in the system of passengers (for all types combined). attitude this amount somewhere on the model in a text-box.

Question 1 (continued) disrupt II agg randizementERNATIVE MODEL (5 points) In PART I, the airline detect that a lot of people who opt for the manual check-in actually dont need the extra services there and could have used the automated check-in.Instead of the original 33% manual check-in and 57% automated check-in, suppose that the airline is able to encourage only 15% of the arriving passengers to go to the manual check-in and 70% to go to the automated check-in. The otherwise(a) 15% of the arriving passengers go right to security. Nothing else in the Part I model changes. * Revise your Part I Arena model to reverberate these changes and name it YournameIT630Q1ALT. doe. Simulate this system for 8 hours and 1 replication. The performance metric of interest is the average total time in the system of passengers (for all types combined).Place this average somewhere on the model in a text-box. PART III ARENA OUTPUT ANALYZER (10 points) You will need to stray the both models for 100 replications. Using the Arena fruit Analyzer, compare the average total time in the system of the BASE model against the ALT model to determine whether or not the changes you make actually made a statistically significant difference. Hint Use the Statistics module. You may want to turn off the animation to speed things up. Run/Run moderate/Batch Run (no animation). Place a screen shot of the Output Analyzer comparison results on the YournameIT630Q1ALT. oe model. In a text-box on the selfsame(prenominal) model, say whether the changes made make a statistically significant difference. * that the Output Analyzer file as OutAnalyzCompareQ1BASE&ALTdrg. - ALL PARTS OF Q1 Arena file names yournameIT630Q1BASE. doe & yournameIT630Q1ALT. doe & yournameOutAnalyzCompareBASE&ALT. dgr Place these three files into folder named yourNameIT630InClassFinalExam.

Restaurant Are na model (25 points) - - One node at a time enters a restaurant according to an Exp(3) minutes distribution. All time is in minutes. This is the lunchtime crowd that eats here between 1130 am and 230 pm. - - Each customer waits Exp(5) for a table. At the table, the customer places an order which is sent from the customer to the kitchen.The kitchen takes Uniform(5. 5, 9. 5) to machinate the food and then it takes Exp(1. 5) for the lunch food to be sent from the kitchen to the customers table. Of course, the food must match up with the particular customer who sent the order. Hint Use a Separate module (and other associated modules) to accomplish this. - - When the order arrives to the customer who sent it, it takes the customer Uniform(12, 17) minutes to eat the meal.Then, the customer leaves the table and queues up at the single cashier where it takes the customer Expo(2. 5) to pay for the meal. The customer then leaves the restaurant. - * - The performance metrics of interest are the 95% Confidence Interval of the average length of time a customer spends in the system and the 95% Confidence Interval of the average number of customers leaving the system after they eat lunch. - -Run the model for 3 hours and make 20 replications. Report the performance metrics in a text-box on the model. Also, if necessary, note any assumptions you made on a text-box on the model. - Arena file name yournameIT630Q2. doe.
