4-18 Hungry's Fine Fast Foods is interested in looking at their staffing for the lunch rush, running from 10 AM to 2 PM. People arrive as walk0ins, by car, or on a (roughly) scheduled bus, as follows:* Walk-ins —–one at a time, interarrivals are exponential with mean 3 minutes; the first walk-in occurs EXPO(3) minutes past 10 AM.*By car —– with one, two, three, or four people to a car with respective probabilities 0.2, 0.3, 0.3, and 0.2; interarrivals distributed as exponential with mean 5 minutes; the first car arrives EXPO(5) minutes past 10 AM.*A single bus arrves everyday sometime between 11 AM and 1 PM (arrival time distributes uniformly over this period). The number of people on the bus varies from day to day, but it appears to follow a Poisson distribution with a mean of 30 people.Once people arrive, either alone or in a group from any source, they operate in-dependently regardless of their source. The first stop is with one of the servers at the order/payment counter, where ordering takes TRIA(1, 2,4) minutes and payment then takes TRIA(1, 2, 3) minutes; these two operations are sequential, first order-taking then payment, by the same server for a given customer. The next stop is to pick up the food ordered which takes an amount of time distributed uniformly between 30 seconds and 2 minutes. Then each customer goes to the dining room. which has 30 seats (people are willing to sit anywhere. not necessarily with their group), and partakes of the sublime victuals, taking an enjoyable TRIA(11,20,31) minutes. After that, the customer walks fulfilled to the door and leaves. Queueing at each of the three "service" stations (order/pay, pickup food, and dining room) is allowed, with FIFO discipline. There is a travel time of EXPO(30) seconds from each station to all but the exit door —-entry to orfer/pay, order/pay to pickup food, and pickup food to dining. After eating, people move more slowly, so the travel time from the dining room to the exit is EXPO(1) minute.The servers at both order/pay and pickup food have a single break that they "share" on a rotating basis. More specifically, at 10:50, 11:50, 12:50, and 1:50, one sever from each station goes on a 10-minute break; if the person due to go on break at a station is busy at break time, he or she finishes serving the customer but still has to be back at the top of the hour (so the break could be alittle shorter than 10 minutes)Staffing is the main issue facing Hungry's. Currently, there are six severs at the order/pay station and two at the pickup food station throughout the 4-hour period. Since they know that the bus arrives sometime during the middle 2 hours, they're considering a variable staffing plan that, for the first and last hour would have three at orfer/pay and one at pickup food, and for the middle 2 hours would have nine at order/pay and three at pickup food (note that the total number of person-hours on the payroll is the same, 32, under either the current staffing plan or the alternate plan, so the payroll cost is the same). What's your advice?In terms of output, observe the average and maximum length of each queue, the average and maximum time in each queue, and the total number of customers completely served and out the door. Make plots of the queues to get into order/pay, pickup food, and the dining room, Animate all queues, resources, and movements between stations. Pick from a. plb picture library a humanoid picture for the entities (different for each arrival source), and make an appropriate change to their appearance after they've finished eating and leave the dining room. Also, while you won't be able to animate the individual servers or seats in the dining room, pick reasonable pictrures for them as well
