Question #1 Airport Terminal Arena poser (25 points substance) lift off I: instauration MODEL (10 points) Management wants to correction Terminal #1 at a hub airdrome with an eventual eye toward improvement. The first step is to nonplus it as it is (i. e. , BASE model) during the eight hours of the busiest part of a typical weekday. You will create an Arena model of the sign in and the hostage operations, only. Once passengers get by dint of security they are on their way to their exhalation gate and leave the system.Passengers arrive one at a time through the effort accession from curbside ground transportation with interarrival times distributed Expo(0. 5) minutes. [All time units are in minutes. ] Of these arriving passengers, 33% go left to an antiquated manual(a) report counter. And, 57% of the arriving passengers go skillful to a new automatize check-in counter. These two types of passengers take no time to move from the front conquer 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. There are two agents at the manual check-in station, cater by a single first-come-first-server 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 change check-in consists of tw o kiosks and is fed by a single first-come-first-server queue. alter 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 thither 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, alloy detector, bag search, etc. Once through security, passengers bye to their gates and leave the model. Simulate this system for 8 hours and 1 replication. The performance metric of engage is the come total time in the system of passengers (for all types combined). repoint this come somewhere on the model in a text-box. Arena file name: YournameIT630Q1BASE. muscularity. buns file into folder: yourNameIT630InClassFinalExam. Warning: It is your responsibility to depict sure that your files are prese nd in your yourNameIT630InClassFinalExam folder and that they open properly. Question #1 (continued) PART II: ALTERNATIVE MODEL (5 points) In PART I, the air hose noticed that a lot of people who favor for the manual check-in really don’t 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 opposite 15% of the arriving passengers go right to security. naught else in the Part I model changes. * rescript your Part I Arena model to mull over these changes and name it YournameIT630Q1ALT. doe. Simulate this system for 8 hours and 1 replication. The performance metric of interest is the mediocre total time in the system of passengers (for all types combined). shoes this reasonable somewhere on the model in a text-box. PART III: AR ENA OUTPUT analyzer (10 points) You will need to run the both models for coke replications. Using the Arena output Analyzer, compare the bonny total time in the system of the BASE model against the ALT model to determine whether or not the changes you made actually made a statistically significant difference. breaking wind: Use the Statistics module. [You may want to turn off the animation to travel things up. draw off/Run Control/Batch Run (no animation). ] Place a screen shot of the widening Analyzer comparison results on the YournameIT630Q1ALT. oe model. In a text-box on the same model, say whether the changes made exploit a statistically significant difference. * Save the Output Analyzer file as: OutAnalyzCompareQ1BASE&ALTdrg. ————————————————- all in all PARTS OF Q1 Arena file names: yournameIT630Q1BASE. doe & yournameIT630Q1ALT. doe & yournameOutAnalyzCompareBA SE&ALT. dgr Place these three files into folder named: yourNameIT630InClassFinalExam. Warning: It is your responsibility to get down sure that your files are present in your yourNameIT630InClassFinalExam folder and that they open properly.Question #2. Restaurant Arena model (25 points) ————————————————- ————————————————- ane guest at a time enters a restaurant according to an Exp(3) minutes distribution.

Of course, the food must duad 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 liquidate for the meal. The customer then leaves the restaurant. —————————— 212;—————- * ————————————————- 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. plow 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. Place file into folder: yourNameIT 630InClassFinalExam.
