digital simulation class: use the simio software as a modeling tool
Two types of travelers (Regular and Frequent Flyer) arrive at the main entrance of an airline terminal. The time between arrivals for the Regular travelers is exponentially distributed with a mean of 2 minutes. The time between arrivals for the Frequent Flyer travelers is also exponentially distributed with a mean of 1 minutes. At the check-in counter, travelers (both types) wait in a single line until one of the three agents is available to serve them. The check-in time follows a triangular distribution with parameters (1, 2, 3) minutes for Regular travelers and a Normal distribution with mean of 1.5 minutes and a standard deviation of 0.5 minutes for Frequent Flyers. A Frequent Flyer traveler spends at least 30 seconds at the check-in counter. Upon completion of their check-in, travelers proceed to Security. The time to go through the Security is uniformly distributed for both types of travelers with parameters (1, 2) minutes for regular travelers and (0.5, 1.5) minute for Frequent Flyers. There are two Security counters and Frequent Flyers are given higher priority over the Regular travelers at the Security After the Security both types of travelers go to the Gates. The time to travel from Arrival to Check-In, from Check-in to Security and from Security to the Gates can be assumed to be Uniformly distributed between (1.2) minutes regardless of the type of traveler Terminal works for 16 hours from 6 am to 10 pm. Agents work for 8 hours and are given staggered break for 30 minutes beginning three and half hours in their shift which means, first shift break will begin at 9:30 am and end at 11 am. During this 1 hour 30 minutes there will be only two agents. The second shift break will similarly begin at 5:30 pm and end at 7 pm. You should verify from your animation that there are only two agents during break times. Develop a Simio based simulation model for this system. Properly label all parts of your model. Show on your animation Regulur travelers as blue arrows and Frequent Flyers as red arrows. Draw a plot (for 16 hours) showing total number of travelers in the airport Run the simulation for 16 hours (6 am to 10 pm) to determine average time in system (flowtime) separately for Regular and Frequent Flyer travelers, number of passengers completing check-in, the average length of check-in queue and average agent utilization. Make sure to change the starting time to 6:00 am and ending time to 16 hours. Make 25 replications and write below, the confidence interval as (mean + half width] or [LCL, UCL) for the following statistics: Average Flowtime of Regular Travelers (minutes) Average Flowtime of Frequent Flyer Travelers (minutes) Average Check-in Queue Length: Average Security Queue Length: Average Agent Utilization (%) Average Security Utilization (96) Two types of travelers (Regular and Frequent Flyer) arrive at the main entrance of an airline terminal.
