Two different queuing systems

Two different queuing agreementsIntroductionThis report presents the modeling of two different queuing strategys in a typical camber environment using the arena software. The assurance legal separations for both the systems are micturateed based on the simulation results. The systems are then compared to hold out which queuing system performs better.AssumptionsFor both systems, no real data was collected. Both the interarrival times and service times were taken from known probability distributions. Other assumptions besides include no balking, reneging and queue jumping. Each replication had the same initial conditions and terminating events. Lastly, both systems are assumed to be s give in, have infinite c solelying community and no limit on system capacity.Modeling of the systemsIn this section of the report, the actual modelings of both the systems using the arena software are discussed. Configuration of the models and steps to run the system are also highlighted. First ly, system 1 is explained, followed by system 2.System 1 modelingSystem 1 has a break away queue for separately individual bank teller. Based on Kendalls notation, system 1 is an M/M/4 system. It is a Poisson puzzle out and disallows batch arrivals. The table downstairs summarizes the categorization of the system based on the parameters of the system.In this system, customers arrive and choose to join the shortest queue. The highlighted mean values in the table represent the exponential mean value ?. For the interarrival time, 100 customers arrive in 1 hour. Hence,= 1/ (100/60) = 0.6Firstly, create the customer arrival portion by clicking and dropping the create button. undermentioned configure it by doubling clicking the diagram. The Figure shows the dialog rap to configure the entity.Type the parameter as shown in Figure 2 above for this system. The kind can also be shown in the figure below.Create the four individual processes for apiece of the Bank Tellers by using the process button. Configure the process as shown below.Since the customers can choose the shortest queue to join upon arrival, create a decision box by using the decide button. Configure the decision box as followsClick on the Add button to include the conditions for the branching conditions. Select Expression and right click and take on expression builder to construct the expressions.Finally, create the customer departure by using the Dispose button. Double click on the button to configure by naming it.Lastly, connect all the components together to model the system 1.System 2 modelingSystem 2 has only a single queue for all the arriving customers. When a bank teller becomes available, the customer will be served by that bank teller. Based on Kendalls notation, system 2 is an M/M/1 system. The table below shows the categorization of the system 2 based on Kendalls notation.Running the SimulationOnce the models of both the system are constructed, simulation runs are conducted to evaluat e the mental process of the systems. The steps in running the simulation are as followsClick on the Run tab and select Setup.Click on the Replication Parameters tab. arousal number of replications as 15 and replication length as 480 change all the units to minutes. This is shown in the Figure below.Click on Run tab and select Go to run the simulation.Simulation ResultsThis section of the report summarizes the results produced by both the queuing systems. The slaying measure parameter is the average time the customer spends in the bank. The results for severally individual system are evaluated and the following confidence interval is constructed. Then the two systems are compared by constructing another confidence interval.System 1 ResultsThe system 1 results are based on the average time a customer spends in the system as its performance measure. The average time for each replication is summarized in the table below.Firstly, the mean is computed using(n) = 4.8121Variance is also computed using(n) = 1.103800987Hence the 95% confidence interval (? = 0.05, t14, 0.975 = 2.145) for system1 is computed usingConfidence interval 4.2302, 5.3940System 2 ResultsThe system 2 results are also measuring the average time the customer spends in the system. The results are summarized in the table below.By using the same formulas, the mean, variance and confidence interval are as follows(n) = 3.804533333(n) = 2.231921051Confidence interval 2.9771, 4.6319Comparison between Two SystemsFrom previous results, the confidence intervals of both the systems overlap each other. Therefore, it is hard to determine which system performs better. Hence, paired- t confidence interval is used to compare the two systems. It is important to note that the number of replications for each system must be the same for this type of comparison. The table below summarizes the results of this comparison.The mean, variance and the confidence interval is computed and the results are as follows(n) = 1.0 07566667(n) = 3.578001252Confidence interval 0.5192, 1.4960Since the confidence interval does not contain zero, there is strong evidence to conclude that system 1s average time customer spends in the system is larger than that of system 2. Hence, system 2 performs better than system 1.ConclusionThis report presents the models of two different queuing systems in a bank environment. Through the simulation results, it is found that system 2 performs better than system 1. In order to get more accurate results, the number of simulation runs must be increased and other performance measure parameters can be tested to further gauge the performance of both the systems.

Pre 1914 Poetry Comparison: Alfred Lord Tennyson, The Charge Of The :: English Literature

Pre 1914 Poetry Comparison Alfred Lord Tennyson, The Charge Of TheLight Brigade, and Wilfred Owen, Dulce Et Decorum Est1) The Charge Of The Light BrigadeTennyson was prompted to write this song after reading an article inthe Times newspaper about the charge of the Light Brigade. Tennysonsmain motive for writing this poem seems to be to keep the braveryof the troops.Tennyson appears to be a patriot. He concentrates on the brave way thesoldiers went into near certain death and only makes star mention ofthe complete cock-up make by the generals. Rather than concentrate onthe mistakes made he sticks with celebrating what the soldiers didWhen can their glory fade? he asks. The use of the rhetorical isalmost challenging you to protest with his opinion of the soldiersbravery.Tennyson uses a lot of things like onomatopoeia, repetition andalliteration. He uses repetition to try and show, in words, theconfusion of the battle. An example of this is stem to right ofthem, Cannon to left of t hem, Cannon in front of them. He uses all ofthese things to try and create imagery of the battle, to help try andimagine what the battle was like. However what he doesnt do is hedoesnt personalise he always generalises. He gives you a picture ofthe battle without actually giving accounts of the actions of the men.The pace of the poem is the same all the way finished except for onepoint at the end of the fourth verse. For most of the poem the pace isquite fast, with a rhythm comparable to the clatter of horses hooves(on economic consumption or by accident?). But near the end of the fourth verse,after speaking of the battle and the slaughter of many men, the paceslows for about one line. Then they rode back, but not, Not the sixhundred. The pause between back and but is cleverly used toemphasise the loss of life.An image that recurs a lot in the poem is prosopopoeia of thevalley into which the Light Brigade rode into some kind of monster, adevourer of human life. The phrases the ja ws of Death and mouth ofHell are used more than once, an important piece of imagery.Alfred Lord Tennyson did not return first hand experience of the battleand it shows in the poem. The Charge Of The Light Brigade is verygeneralised, with the word them constantly being used. No actions or spate of any specific soldier is mentioned its always soldiers ratherthan soldier.My personal reaction to his poem is that it would have been better for

A Fairy Tale :: creative writing

He knew that his first prey, the firebird, lived high up in the trees in the heart of the forest. Like lightening, they were hard to miss, and the raw of its beak left a burn that could never be forgotten. Suddenly, the son heard a shriek, and he whirled his head to see the blood-red bird swooping toward his face. Panicking, the boy lunged for the ground, and for the net that the wise man had given him. He hurled it at the bird - and missed. The bird, angry, made another giant swoop at the boy - and tore its condition as it flew straight into the blade of the boys sword. That was one creature taken care of. His next target, the freezing spider, could be either much harder, or much easier, the boy knew not which. The spider could not run, or jump, unlike some of its relatives, but it was harder to find, and its poison froze the human blood and made its victims help little, lying on the ground frisson until the arachnid finally took pity on his prey and ate it. He tried not to th ink about it.Instead the boy thought of shipway to attract his prey if he could get it to come to him, the killing would be easier - and definitely much safer. The freezing spider would eat any kind of inning it could, but it was well known that the spider loved most to eat the flesh of humans. Well, what should he do? Obviously bait was safer than waiting for an attack, so the boy pulled out his dagger and held it to his upper arm. That was when he saw the grey bristles of the freezing spider. It was sitting quietly on a nearby shrub, its thorn toward the boy. Holding back a sigh of relief, he took one quiet step toward his prey, holding the dagger high, and stabbed it through the spider before it knew what hit it. A little less active a kill than the firebird, but just as exhilarating. Now the only victim left in this task of the boys was the netherworld wolf, and what a creature. approximately the size of a pig, these dogs could tear up a man in two minutes flat, or so it was said. However, being the largest of the creatures made it the easiest target.

John Cabell Breckinridge :: essays research papers

John Cabell BreckinridgeOne day I was walking near the grounds at the capitol building in Frankfort. There tantalize alone in the First Ladys rose garden on a bench was a solemn looking fellow. He looked precise distressed and confused. So, I inquired if he was feeling well or needed something. He replied that he had just discovered everyone he had ever loved was departed and for some odd reason he was all that was left. I wasnt sure what he meant by that so I sat down beside him. He was dressed quit dapper in a dark suit with an upturned quail at and some sort of fanciful scarf wrapped rough his neck very tightly like a tie. I also noticed his plaza appeared to fit either foot and he had a sharp gold watch chain. I image all this was very odd, and assumed he may have been a reenacter at the capitol building. I began to inquire slightly his behavior the following is the account of this bizarre conversation.I started by introducing myself, he said his shape was Gen. John Breckinridge and he was in search of Gov. Leslie. I thought this was odd because Leslie was governor in the late 1800s (1871-75). At first I told him capital of Minnesota Patton was the governor this seemed to confuse him greatly. He asked me where I procured my clothing, I told him in Carrollton. He then asked if I knew Gen. Butler. I replied that I had only known his name and who he was and that I had never met him.

Constitution Position Paper :: essays research papers

The falls of this country are due to the Articles of Confederation and a weak centralized regime. To correct this, a strong field of study government will need to take its place. The majority of this delegation wishes to accept the Constitution as the new federal government of the United States.Many comfortably arguments were brought up during the proceedings such as William Patersons view of revising the Articles and proposing the union of the states as merely federal. Alexander Hamiltons idea of a commanding executive serving during good behavior or life with veto power over all laws. Both of these were rejected. Patersons plan because there are too many faults with the Articles and Hamiltons idea because it is too close to a form of monarchy. The most accepted idea was by Edmund Randolph and James Madison. In it they proposed the government be broken up into three branches legislative, executive, and judicial and each branch to check and balance each others power. This centr alized government would hold in the power to veto laws enacted by state legislatures. The majority of the delegates voted on a supreme power national government over the federations being an agreement resting on the good faith of its members. The many problems in the Articles of Confederation that led us to throw it away rather than to amend it were its inability to tax, no national speak to system, no executive to enforce acts of Congress, lack of regulation of foreign and interstate commerce, amendments with consent of all states, and the fact that the articles are only a firm alliance of friendship that is non-binding. There are too many changes to me made to have the state legislatures vote on it. The result would be no changes for the legislatures stand to jobless power. The only way that changes will be made if we start new.Many new issues came up with the Constitution and they were settled. The issue of legislation was fixed with a two-chambered legislature with two house s where one is represented equally by each state is allotted two votes while the other is based on population. How slaves would be counted was settled where every five slaves counted as three persons.

Reproductive and Therapeutic Cloning Essays -- Technology Science Gene

Reproductive and Therapeutic CloningNew areas of science often face-lift questions ab break safety. Reflecting back on the chivalric medical technologies invented, people have always opposed it but often benefit from it later on in life. The use of in-vitro fertilization, for instance, was once a controversial issue. Some people worried that society could discriminate against humans produced as a result of IVF and humans could administer diseases. Furthermore, its usefulness cannot be predicted because it is just a research tool, and so on. Today, those worries and concerns have not manifested, but instead have brought joy and happiness to families. The people born(p) through IVF process are as happy and equal as any other average child. It is the same with cloning applied science. Upon all that we have gained from historical medical technology, a majority of people have failed to see that new medical breakthrough will become as beneficial as the past ones if it is allo wed to be researched. Cloning is a controversial issue because it is a new area of science and people are once again worried that, this technology will become a dangerous weapon to the society. Cloning is the creating of a genetically analogous copy of an original plant or animal by using biological materials such as DNA segment (e.g. a gene or other region). According to Wilmut, The copies produced through cloning have identical genetic makeup and are known as clones. Many organisms in nature reproduce by cloning (asexually). Scientists use cloning techniques in the laboratory to create copies of cells or organisms with value traits. Their work aims to find practical applications for cloning that will produce advances in medicine, biological research, and industry.... ...ld pass a similar lawfulness and allow at least research, if not experimentation. Anxieties people have about cloning are similar to concerns about past medical technologies. This is also professedly about technologies in general, for instance people questioned the importance and abilities of computers, etc. Some new areas of science in the past brought up apprehensions, these technologies turned out to be beneficial to mankind. Cloning technology is now a new area of science and people are concerned about the safety and morals stern it. This system could become as stable as past medical technologies only if research is allowed. If laws are pass (with some restrictions) it could ensure that research is carried out without interfering with the principles of nature, ensures that everyone has equal access to the technology, and also used in serious cases not for pleasure.
