Read the “JET Copies” Case Problem on pages 678-679 of the text. Using simulation estimate the loss of revenue due to copier breakdown for one year, as follows: 1. In Excel, use a suitable method for generating the number of days needed to repair the copier, when it is out of service, according to the discrete distribution shown. 2. In Excel, use a suitable method for simulating the interval between successive breakdowns, according to the continuous distribution shown. 3. In Excel, use a suitable method for simulating the lost revenue for each day the copier is out of service. 4. Put all of this together to simulate the lost revenue due to copier breakdowns over 1 year to answer the question asked in the case study. 5. In a word processing program, write a brief description/explanation of how you implemented each component of the model. Write 1-2 paragraphs for each component of the model (days-to-repair; interval between breakdowns; lost revenue; putting it together). 6. Answer the question posed in the case study. How confident are you that this answer is a good one? What are the limits of the study? Write at least one paragraph.

Case Problem
James Banks was standing in line next to Robin Cole at Klecko’s Copy Center, waiting to use one of the copy machines. “ Gee, Robin, I hate this,” he said. “We have to drive all the way over here from Southgate and then wait in line to use these copy machines. I hate wasting time like this.” “I know what you mean,” said Robin. “And look who’s here. A lot of these students are from Southgate Apartments or one of the other apartments near us. It seems as though it would be more logical if Klecko’s would move its operation over to us, instead of all of us coming over here.” James looked around and noticed what Robin was talking about. Robin and he were students at State University, and most of the customers at Klecko’s were also students. As Robin...

Introduction
JetCopies is a business venture of a couple of young men who had the insight to open up a copy business. James Ernie and Terri received a loan from Terri’s parents of $18,000. Due to information they have received the large copier they purchased has a history of breakdowns often for a few days. So the three guys are looking into possibly getting a smaller copier. The purchase of the smaller copier can be used while the other larger copier is being repaired. Before they ask anyone about loaning them any additional money they would like to come up with a simulation to show why the purchase of the smaller copier would be beneficial. The cost of the smaller copier is $12,000.
Breakdowns
I used originally 20 breakdowns but then I ended up going to 13 breakdowns. I then created a list of random numbers. The list of random numbers was figured out in excel with the formula =RAND. Which is depicted by the column r2. After obtaining these random numbers and then using the chart that was provided below I then reviewed my random numbers to see where they fell inline with the repair time day chart. The chart was gathered by Terri from the college of business in which the point was to try and get an understanding how long it would...

Introduction
Before starting the case, it is important to know how this case will be evaluated through excel, the functions and their application, and how they quantifiably accentuate on the variables and known possibilities of the case. The major functions that are used in this particular case are RANDBETWEEN and SQRT in order to identify the relationship of how they simulate and validate the confidence in the results.
RANDBETWEEN & EXCEL
Excel is an excellent application, which has many functions not only of mathematical calculations, like logic. Most people see it as a "challenge", which actually is not. Always bear in mind that Excel is nothing but a game of battleship. This is a set of lines and columns, which are the vessels, and based on the crossing of these lines and columns; seek to achieve the most likely target.
In Excel we have to view the location of each row and column, finding the respective numbers of rows and columns of letters, to achieve the desired end result. I suggest you use it to try to enter their functions, avoid the maximum use of the wizard, it somehow becomes a "settling" deprives us of better assimilate the functions. Typing functions makes...

...JETCopiesProblem
The simulation of JetCopies can be done by generating random numbers from given probability distributions. The different steps of this simulation and assumption made are explained below.
1. Simulation for the repair time.
It is given that the repair time follows
Repair Time (days) Probability
1. .20
2. .45
3. .25
4. .10
-----
1.00
To generate a random number from the above distribution, we use the following procedure.
Generate a random number denoted by r2 from between 0 and 1. If this generated random number is less than or equal to 0.2 take repair time = 1. If the generated random number is 0.2 to 0.65, we take repair time =2. If the generated random number is 0.65 to 0.90, we take repair time = 3 and take 4 otherwise.
2. Simulation for break-down Distribution
Given that the probability distributions of random variable X representing the time between break-downs varies from 0 to 6 weeks with probability increasing continuously, the copier went without breaking down can be approximated by the probability distribution
f(x) =x/18 0 < x < 6
Hence the distribution function of x is
F(x)=x2/36 0 < x < 6
If r1 is another random number generated between 0 and 1, then we can write
r1= x2/36
Hence x=6[pic]...

...assignment, we had discussed the background and the introduction of the company, which wants to cater to this segment. This paper will discuss the long-term capital budgeting decisions that such a company needs to make.
Online a plan those managers in the low-calorie microwavable food company could follow when selecting pricing strategies for making their products as inelastic as possible.
The company aims to keep the prices of its products as inelastic as possible. This means that the pricing strategy should have no impact on the way the consumers perceive and buy such products. Generally we see such demand only in situations in which the good or services are indispensable and the consumers cannot do without those. However, this is not the case for microwavable food products. There is competition in the market to keep the prices under check. Hence, the company needs to do two things to make its prices inelastic-
First of all the company needs to spend money on the R&D efforts to differentiate its products from the rest of the players. This differentiation depends on the core product, advisory service that comes along with the product, packing, availability, support services or virtually anything else.
As the second measure, it needs to send down two important messages to its potential as well as current customers through its marketing communication efforts- First that the low calorie food should not be choice but essential and second that the company...

...• Introduction
Telstra is one of the Australia’s leading telecommunications provider. For many years Telstra owned monopoly in telecommunication market. A change in government policy to reduce the monopoly power of Telstra has resulted in many problems. Telstra is following Classical approach of management as it seeks to achieve effectiveness by focusing on task efficiencies i.e. focusing on their next G wireless broadband and not on external stakeholders (Schermerhorn, Davidson, Poole, Simon, Woods, Chau, 2011, pg. 183). Telstra needs to use more humanistic or contingency approach of planning. This report will argue the need for Telstra to use more contingency approach of planning to regain its market dominance.
• Problem Identification
Telstra as a telecommunication provider has many external environment which it needs to take into consideration while making decision. In particular, government change in decision has led into many problems that Telstra is currently facing. Telstra was following non-competitive behavior as Telstra owned the network as a wholesaler and also sold the network to customers as retailer.
Telstra also needs to change its classical approach of planning into contingency or humanistic approach of planning. So, that it can cope with uncertainty as contingency planning assume various set of assumptions about the future and help to minimize the risk of negative events...
