Simulation 2 Write-Up During the simulation there were many different factors leading to varying results. One of the biggest causes for variation was in the performance of the worker. The worker had the impression that they were under a time constraint. The performance of the worker was usually kept constant until the last 5 or 10 drawings of cards, which is when the worker felt the pressure to draw cards faster. Another cause of variation was the shuffling of the worker. If the worker didn’t shuffle the cards thoroughly it would result in a varied outcome from normal results. This variation is considered a normal cause for variation because as the time constraint became more noticeable the workers would shuffle differently. This occurred more on the last few draws each round. One special cause occurred when the professor walked over to our workstation and had a conversation. This distracted the worker and simulated a special cause for variation. In order to improve the process, I would first designate a worker for shuffling the cards so we could eliminate time used passing the cards. This worker would then split the cards into two piles. Then I would assign two other workers the jobs of counting the cards after they have been separated. The workers would then both tell a single recorder the amounts to be recorded. This would be repeated with the designated shuffler. In order to assure that the second supplier is delivering the promised quality, we made a second quality control chart. This would be done using the same process as the first round. According to our results, the second supplier delivered better results. The proportion of hearts varied less with the second supplier. Using only 15 samples we were able to draw this conclusion. It is half the samples as the other round but due to the fact that the variation was significantly smaller, even if we did 30 rounds the results would be very similar. One thing I took away from the simulation is how division of work can increase efficiency. Our group started implementing a program similar to a division of labor towards the end of the first round and the second round. This not only increased the quality of the “product” that our “company” created, but it helped increase worker efficiency. This is similar to real life situations in which a business needs to also focus on its internal processes. There are several times where a business may want to blame someone other than itself. Using our simulation results we significantly increased our efficiency by changing worker processes.

...75, 100, 500 and 1000 The Simulation has been designed using the computer based program Excel. It is formed to understand the probability of at least 2 people sharing the same birthday in randomly selected groups of 25, 50, 75, 100, 500 and 1000. The simulation is run for 30 iterations for each group that means that the simulation for 25 randomly selected people will be run 30 times and so on. Assumptions v The year has 365 days (not considering the leap year). v Every day of the year has an equal probability for a birthday to occur. v The year of the birth is not considered; only the date and the month are considered. v Any other factor influencing the birth such as human behavior or weather etc. is not taken into account. v Twins or triplets are not in same group. A. · Open the new excel file, name it Task1, save it on desktop. Take the cursor to cell A1 (the horizontal column is represented by alphabets and vertical rows by numbers and each of the box is called a cell). Write Group 1 and drag it horizontally up to 30 columns the last cell would have Group 10. · In cell A2 write the formula =RANDBETWEEN (1,365) and enter (we are taking the number of days in a year as we cannot take the dates of months).

... This and other SimBio Virtual Labs® are accessible through SimBio’s SimUText System®. . SimBio Virtual Labs®: EcoBeaker® The Barnacle Zone Background When we tell our kids about different species and where they live, we naturally start talking about weather and the physical environment. Camels are adapted to life in the desert and can go a long time without water. Polar bears live in the Arctic and are adapted to cold with their thick layers of insulation. A polar bear wouldn’t be very happy in the desert, and a camel would have a hard time in the Arctic (though a herd of camels pulling a sled over the ice is an amusing image). The underlying idea is that in order to be adapted to one environment, you necessarily give up the ability to live in other environments. But is this true for most species? Do species live where they do primarily because of their adaptations to the physical environment, or might the other species in the environment also be important? The intertidal zone of rocky coastlines makes an interesting natural laboratory in which to explore these questions. First, the physical environment itself is challenging. The intertidal zone is that portion of the shore that is covered during high tide and exposed to air during low tide. If you think about how rocks would be covered and exposed as tides come in and out (twice a day on average), you can see that, the higher an organism lives on the rocks, the more time it will...

Nvq L3 Assessing Vocational Acheivent T3 Assignment

...Witness Testimony A witness testimony is a piece of evidence that is provided by an individual that has closely worked with the candidate. A witness testimony can be used to clarify that the candidate has shown knowledge and performance skills throughout the work place. The assessor only has a limited amount of time to spend with each candidate so using this assessment method allows others to contribute in the assessment process. Witness Testimonies can provide useful information to the assessor but only when the source is valid and reliable. Evidence provided by the witness should be fair, reliable, valid and appropriate to standards and criteria of the specific qualification. The evidence should be signed and dated by the witness and if felt appropriate the assessor should communicate with the witness to confirm authenticity. A copy of the witness testimony should be placed into each candidate’s profile. This is to ensure that if an internal verifier was to check then all the information and evidence will be present. The information provided by the witness testimony should never be used upon solely to make an assessment decision. The assessor should use the information gathered as a guide to help inform them in making the correct assessment decision. A witness testimony can be conducted by a colleague to the client who does a similar role or who has experience or perhaps more appropriately a supervisor or manager could do this for the assessor. Whoever does it, they need...

Analysis of Statistical Models for the Simulation of Rayleigh Faded Cellular Channels

...CAREER EPISODE ONE Analysis of Statistical Models for the Simulation of Rayleigh Faded Cellular Channels 1.2 Background 1.2.1 Nature of the project The successful design and testing of mobile communication systems requires a thorough understanding of the underlying radio propagation environment. This has motivated the development of standardized channel models and methods for the simulation of mobile radio channels. The primary goal of any channel simulation model is to reproduce the statistical properties of the real world channel as faithfully as possible. The main idea behind a class of sum-of-sinusoids (SoS) channel models is to simulate the channel as a stationary complex Gaussian random process, formed by the sum of multiple sinusoidal waveforms having frequencies, amplitudes and phases that are appropriately selected to accurately reproduce the desired statistical properties. 1.2.2 Aims of the project This project aims to compare the statistical SoS methods in terms of their complexity and performance. My partner and I decided to compare the Level Crossing Rate (LCR) and Average Fade Duration (AFD) for various models. 1.2.3 Chart of team organization This project was carried out in a two-member team. I was in charge of the team. The organization of the team is shown as below (Table 1): |Stage 1 |Literature Review; | | |Model Selection ...

Monte Carlo

...Monte Carlo Simulation Tutorial This tutorial shows how to use Microsoft Excel to develop Monte Carlo simulations without the use of add-ins or special software (such as @RISK or Crystal Ball). (Note, however, that there are some important advantages of using these dedicated software packages.) After completing the tutorial you should have a sufficient understanding of Monte Carlo concepts and Excel capabilities to begin building your own Monte Carlo simulations applied to a wide range of business problems, including the construction of short-term profit plans (otherwise referred to as “Cost-Volume-Profit” models, covered in Chapter 9 of the text). Monte Carlo refers to a widely used approach for solving complex problems using computer algorithms to simulate the variables in the model (e.g., a CVP model). Typically, an algorithm is developed to "model" the problem, and then the algorithm is run many times (from a few hundred up to millions) in order to develop a statistical data set for how the model behaves. Simple Example: Tossing a “Fair” Coin—Heads vs. Tails? For the simplest example, consider the basic coin toss. This is a process which has two possible outcomes (heads or tails), each with a 50% probability. In a million coin tosses, roughly half will be “heads” and half will be “tails.” A simple Monte Carlo simulation would support this conclusion. If you were to develop a spreadsheet with a random number generator resulting in 0 for “heads” and 1 for “tails,”......

...CHAPTER 5 – ARRAYS CASE STUDY SCENARIO Sorting Data A dozen umbrellas lie on the ground just inside the classroom door when Dr. Taylor begins his lecture. “A cold, rainy day like today makes me want to stay in and order pizza for delivery rather than go out myself.” Handing a phone book to a student in the front row, Dr. Taylor says “Gail, please look up the phone number for Domino’s Pizza on Main Street, and if you don’t mind, I will time how long it takes you to find the number.” Gail flips through a few pages while Dr. Taylor looks at his watch. “Here it is . . . 555-8275,” she says. “Seven seconds. Thank you Gail.” Dr. Taylor presses some keys on his cell phone while continuing his conversation. “Now please look up the name of the person with the phone number 555-5982, and again I will time you.” Dr. Taylor’s focus returns to his watch even as he speaks into the phone. Gail slowly flips a couple of pages, then stops just about the same time Dr. Taylor ends his call. “I assure you the number is in there, Gail. We will wait while you look it up.” “You will probably wait a long time,” she says, “because there is no fast way to find a number.” “Why not? It’s the same data.” “But the phone book is sorted by names, so finding a name is easy. Finding a number is very difficult because a phone book is not sorted by numbers.” Dr. Taylor takes the phone book from Gail. “Exactly! The sorting process does not change the data, but it organizes the data in a......

...Chapter 1 Discrete Probability Distributions 1.1 Simulation of Discrete Probabilities Probability In this chapter, we shall first consider chance experiments with a finite number of possible outcomes ω1 , ω2 , . . . , ωn . For example, we roll a die and the possible outcomes are 1, 2, 3, 4, 5, 6 corresponding to the side that turns up. We toss a coin with possible outcomes H (heads) and T (tails). It is frequently useful to be able to refer to an outcome of an experiment. For example, we might want to write the mathematical expression which gives the sum of four rolls of a die. To do this, we could let Xi , i = 1, 2, 3, 4, represent the values of the outcomes of the four rolls, and then we could write the expression X 1 + X 2 + X 3 + X4 for the sum of the four rolls. The Xi ’s are called random variables. A random variable is simply an expression whose value is the outcome of a particular experiment. Just as in the case of other types of variables in mathematics, random variables can take on different values. Let X be the random variable which represents the roll of one die. We shall assign probabilities to the possible outcomes of this experiment. We do this by assigning to each outcome ωj a nonnegative number m(ωj ) in such a way that m(ω1 ) + m(ω2 ) + · · · + m(ω6 ) = 1 . The function m(ωj ) is called the distribution function of the random variable X. For the case of the roll of the die we would assign equal probabilities or probabilities 1/6 to each of the outcomes....
