Question #1 Airport Terminal Arena model (25 points total) PART I: BASE MODEL (10 points) Management wants to study Terminal #1 at a hub airport with an eventual eye 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 Arena model of the check-in and the security operations, only. Once passengers get through security they are on their way to their departure gate and leave the system.Passengers arrive one at a time through the front entrance 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 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. There are two agents at the manual check-in station, fed 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 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 typ es 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, etc. 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 average total time in the system of passengers (for all types combined).Place this average somewhere on the model in a text-box.

Warning: It is your responsibility to make sure that your files are present in your yourNameIT630InClassFinalExam folder and that they open properly. Question #1 (continued) PART II: ALTERNATIVE MODEL (5 points) In PART I, the airline noticed that a lot of people who opt 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 other 15% of the arriving passengers go right to security. Nothing else in the Part I model changes. * Revise your Part I Arena model to reflect 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 run the both models for 100 replications. Using the Arena Output 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 made actually mad e a statistically significant difference. Hint: Use the Statistics module. [You may want to turn off the animation to speed things up. Run/Run Control/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 same model, say whether the changes made make a statistically significant difference. * Save 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.

Correspondence packet - Article Example This social group has proved to constitute the bulk of our consumer audience (which isn’t surprising as the clothes produced by our company are orientated on youth), and we need to sense their needs and tendencies in their behavior accurately in order to increase our benefit. Thus, as marketing researches show, the internet has become virtually the main tool for advertising and promoting goods among a very wide category of consumers. Thus, our target audience tends to use the internet the most among all other media, and it is the area where we need to display our significant place in fashion clothing industry. Our surveys show that about three quarters of our target audience tends to use internet daily. On the other hand, popularity of television has dropped considerably in the recent years. This tendency, as you can clearly see, has a profound impact on our industry, too, as we currently focus our major efforts on the outdoor advertising and TV commercials. DIVERSE clothes, Inc. must shift focus from TV advertising to the Internet advertising using all its means like banners, pop-ups and e-mail ads. Changing our strategy will allow us to reach the greater number of our potential consumers who are young adults. The World-Wide-Web provides a valuable platform to place ads with the aim to reach millions of consumers around the world (Hamel). Again, surveys indicate that such websites as Google, Facebook, Yahoo!, Twitter and YouTube are among the top 10 most visited websites. This gives us a hint about where our efforts should be concentrated therefore. If we shift focus from radio and TV advertising to the popular Internet sites, we will increase popularity of our company and achieve much success in promotion of our products. And, obviously, the rate of sales is likely to increase considerably. Concerning the financial aspect of the issue, I would like to suggest simply redirecting

Understanding Culture Shock Essay Example | Topics and Well Written Essays - 1750 words

Understanding Culture Shock - Essay Example In the movie, Ashoke Ganguli (Irfan Khan) brings his new bride Ashima (Tabu) to New York (location change from a book!) from Calcutta. She shrinks his sweaters in the wash, eats her breakfast cereal with peanuts and chili powder, and generally does the best she can to adapt to this cold new country. Their first son is nicknamed Gogol after Ashoke’s favorite author, a placeholder name as they wait for a â€Å"good name† to come from Ashima’s mother in India. This pet name, however, takes hold, at least until Gogol Ganguli (Kal Pen) decides in high school to change his name back to his good name - Nikhil. He grows up, becomes an architect, rebels against his parents by dating a wealthy white girl (Jacinda Barret), then falls for a Bengali girl (Zuleikha Robinson) and attempts to reconcile his two names, two identities Some of the symptoms of culture shock as seen in the movie are excessive concern over cleanliness and the feeling that what is new and strange is "dirty." This could be in relation to drinking water, food, dishes, and bedding; fear of physical contact with attendants or servants; a feeling of helplessness and a desire for dependence on long-term residents of one's own nationality; irritation over delays and other minor frustrations out of proportion to their causes; delay and outright refusal to learn the language of the host country. Individuals differ greatly in the degree to which culture shock affects them.  

Stadiums are bad for economy of a city and tax payers pay the cost (4 Research Paper

Stadiums are bad for economy of a city and tax payers pay the cost (4 real life examples, TABLES AND CHARTS) Cost enefit analysi - Research Paper Example However, the income generated in the stadiums does not directly benefit the taxpayers and the residents of the city. The amount that the fans spend when watching a match does not benefit those who work in the stadiums. The amount does not lead to increased growth of the local economy because the amount is not included in the local economy. The employees, who work in the stadiums and other sources of the stadiums like the taxpayers, do not benefit from the money earned. Instead, the biggest share of the amount pays the players. However, most of these players in many cases do not belong to the local community. Therefore, the local community, which pays tax to help in construction of the stadiums, does not benefit too. Though the stadiums collect large amounts of money, the money is spent in other locations (Barros et al. 42). Taxpayers who contribute towards the construction of the stadiums do not attend the events that take place in the stadiums yet they pay for the events indirectly through tax. Stadiums fail to improve and develop the local economy because it concentrates more on the intensity of labour. In this case, low levels of unskilled type of labour activities take place within the metropolitan area. The people who benefit from this type of unskilled labour do not get high wages or salaries. This leads to a fall in the share of the income of the region because those who are highly skilled do not get a chance to get a job in the stadiums. The jobs that the local community gets are either temporary types of jobs or part time jobs, which are not effective to improve the economy of the local region that has the stadium facility. Construction of a stadium assists a team from the community. However, the players who play for the city do not live in the city. The assumption made by the metropolitan is that even if the players do not contribute much in building of the stadium, maybe they spend their money doing shopping and paying house taxes (Andreff and Szyman ski 56). However, most players have houses far away from the cities in where they live with their families, do shopping, and spend their leisure time. The space used to construct the stadium is large enough hinder expansion and development of a city. Those people whose land is taken to cater for the area of construction of the stadium get angry and leave the city (Morris 67). However, the people who leave the city may be good businesspeople who can invest and create job opportunities for the local community and by doing so; the economy of the city can grow to a higher level. Some of those people could be good investors, and this hinders them from investing in construction of commercial buildings, which would bring more income to the city through tax and to the dwellers of the city. When a city lacks potential investor to invest in the transportation sector and other smart type of investments, which lead to economic growth, the economy is likely to go downwards. Therefore, constructi on of the stadium does not support a city’s expansion and development. The cost of operating the stadium is very high. However, this amount used in maintenance and operations in the stadium

Reasons for Quarrels between Friends Essay Example | Topics and Well Written Essays - 750 words

Reasons for Quarrels between Friends - Essay Example .. severe and demonstrate a lack of trust and respect. In these cases, a firm break up may be the right answer. â€Å"She goes on to explain the reasons as to why friends could end up arguing and what the end result of that action brings for the parties concerned. As we grow up, we come to realize that we may have a lot of friends, but only one whom we feel deeply close and connected to. That person is termed as a best friend. A best friend is someone whom we share our inner most thoughts and feelings with. That friend is the physical representation of the trust that we have learned to share with other people. Then something happens, your best friend betrays you for some reason. The betrayal could be something as petty as telling your parents about the day that you skipped school to go see a movie or something major (as in the case of adults) that resulted in the breaking of the trust because your best friend told someone else about your secret or, in some cases, started some gossip about you based upon the secrets that you told her. Whatever the reason, the trust you gave that person was broken. The betrayal you feel can be so severe that arguing with your friend does not produce a healthy solution to the situation. Sometimes the only logical path for your relationship to take with that person is to end the friendship since the sense of betrayal is sometimes overwhelming. Other times the reason for the break-up or quarrel in a friendship stems from the lack of support from people whom you expected to have your back during rough patches of your life. Say for example you move to a new school but still live in the same neighborhood. Your classmates used to be the same kids who lived on the same block. Now, you have a totally new set of classmates whom you have to adjust to because the new school standards and social set up is a far cry from your old one. When you get home, you expect to see your neighbors, whom you consider to be friends, and spend time with the m. Sharing your thoughts and feelings and just letting them know how hard it is to adjust to your new set up. However, instead of lending you an ear and offering you a shoulder to cry on, your friend or friends choose instead to make a joke out of your situation and make you feel like an outsider within a group of people whom you thought were your friends. This lack of support can often be a major cause of friction between friends that could also lead to the breakup of friendships if the problem is not resolved in time. Oftentimes such cases of lack of friend support are just a minor reason for arguments between friends and, if caught in time, the friendship can actually still be mended. Let's not forget, arguments between friends can also be caused by petty jealousy over things as simple as who looked better in an outfit, or who got the higher grade in a test. This feeling of inferiority between friends often results in the jealous friend acting all unreasonable and mean towards th e other friend who is deemed to have gotten the better result in a given situation. This failure to be happy for the success of other friends is a major cause of arguments between friends but can usually be ironed out in the end with a simple explanation. Jealousy does not often result in the end of

Written Report for Professor in Chem Department (new gas-phase ion Essay

Written Report for Professor in Chem Department (new gas-phase ion chemistry and mass spectrometric ) - Essay Example In 1999, she received an outstanding Graduate award of Lanzhou University and consequently the same award at the Chinese Academy in 2002. In 2012 at Purdue University, she received a Research foundation faculty international grant. Finally, for her mastery in mass spectrometry, the American society honored her with Mass Spectrometry Research Award (Chem.purdue.edu). On joining Purdue, professor Yu had little information with the use of instrumentation, but quickly she gained mastery of the sophisticated apparatus. Professor Xia, a daughter of high-school chemistry teacher developed her interest in chemistry early life and was further influenced by her father. Her enthusiasm is evident in several interviews whereby she states that she always aspired to be a chemistry researcher and the PdD training proved a genuine pathway to success. She further acknowledges that she always wanted to be a researcher and chemistry Purdue chemistry program is very reputable. (Chem.purdue.edu). Professor Yu’s research focal point is on generating new ways for analyzing carbohydrates and proteins using mass spectrometry and new gas-phase ion chemistry. This bio-analysis process aims to utilize radical reactions as an approach to exploring radical ion chemistry. Her interest and that of the group is to develop tools for bio-molecular structural clarification through instrumentation, bio-radical chemistry and MS method of development. Through instrumentation, Xia and group develop mass spectrometry systems for executing bimolecular reactions in both a linear trap and plume sections of nano-electrospray source. These ranges of apparatus enable research transition from the radical attack study of biomolecules to the analytical study (Chem.purdue.edu). In terms of bio-radical chemistry, radical ions can be formed in the gas phase on principle of radical reactions.

Fundamental of International Buisness Essay Example | Topics and Well Written Essays - 500 words

Fundamental of International Buisness - Essay Example It describes the increase of trade and investing due to the falling of barriers and the interdependence of countries, particularly trade liberalisation or "free trade" (Globalization, 2005). So, the main driven forces of the Southeast Asia market include political, social and economic changes. Political driven forces were caused by changes in political doctrines. Primarily, a struggle between socialist and capitalist countries is over (Buckley, Ghauri, 1999). If we assume that "the essence of globalization is a subordination of human rights, labor rights, consumer right" (Ralph Nader), we should accept the view that trade and market relations is nothing more than subordination of human rights. But it is not true. To support this point of view, it is possible to use the theory of Adam Smith who wrote that markets function without conscious control because individuals take their private decisions in response to publicly-known signals (Himmelweit, et al. 2001). It is possible to agree t hat American and European companies create jobs overseas at the expense of domestic jobs, which does not break the rights of workers from the poorest countries. In addition, the globalization of industries has created surplus production capacity on a massive scale. Proposition of quality products which compete with the national brands does not humiliate consumers rights.
