palisade decision tool, and excel
The purpose of the assignment is to gather the information needed to
set up problems, run simulations, and interpret the results to solve
the problems.Using specified data files, chapter example files, and templates
from the “Topic 2 Student Data, Template, and Example
Files” topic material, complete Chapter 15, Problems 2, 7, 9, 32
(parts a and b only), 33, and 35 from the textbook. Use the Palisade
DecisionTools Excel software to complete these problems where
requested and applicable. Problem 2 only requires the use of Microsoft
Excel; however, you may optionally use the Palisade DecisionTools
Excel software to generate the histogram.Use the Palisade DecisionTools Excel software to complete the rest
of the problems and ensure that all Palisade software output is
included in your files. Unless otherwise stated, run simulations with
1,000 trials. Use 500 trials if the software will not allow you to run
1,000 trials. Ensure that only one Excel file is open when running a simulation.To receive full credit on the assignment, complete the following.Ensure that the Palisade software output is included with your
submission.Ensure that Excel files include the associated
cell functions and/or formulas if functions and/or formulas are
used.Include a written response to all narrative questions
presented in the problem by placing it in the associated Excel
file.Include screenshots of all simulation distribution
results for output variables.Place each problem in its own
Excel file. Ensure that your first and last name are in your Excel
file names.APA style is not required, but solid academic writing is expected.This assignment uses a rubric. Please review the rubric prior to
beginning the assignment to become familiar with the expectations for
successful completion. 2.Use
Excel’s functions (not @RISK) to generate 1000random numbers from a
normal distribution with mean 100 and standard deviation 10. Then freeze
these random numbers.a.Calculate the mean and standard deviation of
these random numbers. Are they approximately what you would
expect?b.What fraction of these random numbers are within k standard
deviations of the mean? Answer for kkk=1; for k=2; for k=3. Are the
answers close to what they should be (according to the empirical rules
you learned in Chapters 2 and 5)?c.Create a histogram of the random
numbers using 10to 15 categories of your choice. Does this histogram
have approximately the shape you would expect?
7.Use
@RISK’s Define Distributions tool to draw a triangular distribution
with parameters 200, 300, and 600. Then superimpose a normal
distribution on this drawing, choosing the mean and standard deviation
to match those from the triangular distribution. (Click the Add Overlay
button at the bottom of the window and then choose the distribution to
superimpose.)a.What are the 5th and 95th percentiles for these two
distributions?b.What is the probability that a random number from the
triangular distribution is less than 400? What is this probability for
the normal distribution?c.Experiment with the sliders to answer
questions similar to those in part b. Would you conclude that these two
distributions differ most in the extremes (right or left) or in the
middle? Explain.
9.A
company is about to develop and then market a new product. It wants to
build a simulation model for the entire process, and one key uncertain
input is the development cost. For each of the following scenarios,
choose
an appropriate distribution together with its parameters, justify your
choice in words, and use @RISK’s Define Distributions tool to show your
cho-sen distribution.a.Company experts have no idea what the
distribution of the development cost is. All they can state is “we are
95% sure it will be at least $450,000, and we are 95% sure it will be no
more than $650,000.”b.Company experts can still make the same statement
as in part a, but now they can also state: “We believe the distribution
is symmetric, reasonably bell-shaped, and its most likely value is
about $550,000.”c.Company experts can still make the same statement as
in part a, but now they can also state: “We believe the distribution is
skewed to the right, and its most likely value is about $500,000.”
32.A
hardware company sells a lot of low-cost, high-volume products. For one
such product, it is equally likely that annual unit sales will be low
or high. If sales are low (60,000), the company can sell the product for
$10 per unit. If sales are high (100,000), a competitor will enter and
the company will be able to sell the product for only $8 per unit. The
variable cost per unit has a 25% chance of being $6, a 50% chance of
being $7.50, and a 25% chance of being $9. Annual fixed costs are
$30,000.a.Use simulation to estimate the company’s expected annual
profit.b.Find a 95% interval for the company’s annual profit, that is,
an interval such that about 95% of the actual profits are inside it.
33.
W. L. Brown, a direct marketer of women’s clothing, must determine how
many telephone operators to schedule during each part of the day. W. L.
Brown estimates that the number of phone calls received each hour of a
typical eight-hour shift can be described by the probability
distribution in the file P15_33.xlsx. Each operator can handle 15 calls
per hour and costs the company $20 per hour. Each phone call that is not
handled is assumed to cost the company $6 in lost profit. Considering
the options of employing 6, 8, 10, 12, 14, or 16 operators, use
simulation to determine the number of operators that minimizes the
expected hourly cost (labor costs plus lost profits).
35.Lemington’s
is trying to determine how many Jean Hudson dresses to order for the
spring season. Demand for the dresses is assumed to follow a normal
distribution with mean 400 and standard deviation 100. The contract
between Jean Hudson and Lemington’s works as follows. At the beginning
of the season, Lemington’s reserves x units of capacity. xxLemington’s
must take delivery for at least 0.8xdresses and can, if desired, take
delivery on up to xdresses. Each dress sells for $160 and Hudson charges
$50 per dress. If Lemington’s does not take delivery on all x dresses,
it owes Hudson a $5 penalty for each unit of reserved capacity that is
unused. For example, if Lemington’s orders 450 dresses and demand is for
400 dresses, Lemington’s will receive 400 dresses and owe Jean
400($50)+50($5). How many units of capacity should Lemington’s reserve
to maximize its expected profit?
AND THESE 2 QUESTIONS... Question 1-Consider the following scenario and address the questions that follow.Suppose your company wanted to determine the amount of sales of a new SUV model, called Lightning.
The sales estimate would be based on the overall demand of various SUV
model types. Overall demand is assumed to be normally distributed with a
mean of 3 million units and standard deviation of 500,000 units. The
share of demand that Lightning will take is assumed to be 4%.
After running 1,000 simulated scenarios, a 95% confidence interval was
constructed for the expected sales of Lightning units sold with limits of 93,048 and 146,964.If 1,000 new simulated scenarios were run, would you get the exact result? Explain why.Would the results be more stable if you ran 2,000 runs? Explain why.Is there a number of simulations that can be run so that the results do not change if you re-ran the simulations? Explain. QUESTION 2- Reconsider the scenario presented in DQ 1 and address the questions that follow.
