Assignment title: Management
Create the application and/or a web site for a business (choice is yours).You must use five (5) programming techniques discussed in this class.Should be database driven with at least 25 products.Compile and test the application before you submit it.
Your final submission for this class will consist of the application and/or a web site plus all project files (code files and other project files);Your code project must be in C# or VB using ASP.NET 4.0 (exactly what we have been using for the entire class) for this project - NO EXCEPTIONS.
Exam 2: Final Examination
1. Problem 1: The file Walmart Closing Prices, posted on Angel contains a little more than
a year's worth of the daily closing values of Walmart's stock from 2003 and 2004. Use
this data to develop a forecast for the day following the end of the data (October 16
2004.)
Use the following forecasting methods:
i) Moving average forecasting with a span of 3.
ii) Exponential Smoothing with a smoothing constant α=0.5.
Use a data table to give the Forecast for 10/16/2004,MAD and MSE as the
smoothing constant in part ii) varies from α=0.1 to 0.6 in increments of 0.1.
Problem 2:
1. A contractor has found that her cost for a certain construction job is subject to random
variation. She believes its actual value follows a continuous uniform distribution
between $9000 and $11000 with a mean of $10,000. The cost to prepare her bid is
$500. She is competing in a sealed bid competition with four other contractors. She
believes that the bids submitted by the other contractors will vary triangularly with a
minimum equal to her minimum cost, a most likely value equal to her 1.3 times her
mean cost and a maximum equal to 2.5 times her mean cost and that their bids are
independent of each other. She will win the competition if her bid is smaller than the
bids of all four competitors. If she wins, her profit will be the difference between her
bid and her cost minus the proposal preparation cost. If she loses her proposal
preparation cost is lost and her profit is -$500.
Simulate 1000 bids in which her bid amount is $14,000 and determine the distribution
of her profit. Include the histogram in your response. Also determine the probability
that she wins the competition and the probability that she loses money. Compare these
results for bid amounts of $13000 and $15000
Problem 3:
Consider the Special Products break even analysis spreadsheet in Figure 1.1 on page 7 of the
text. You will find the spreadsheet on your CD.
The production manager has decided to order a production run of Q=35000. Use simulation to
find the distribution of profit given the following random inputs:
2
The fixed cost varies uniformly between 9 and 11 million dollars. The marginal cost is normally
distributed with a mean of $1000 and a standard deviation of $200. The Sales Forecast is
triangularly distributed with a minimum of 20000, a most likely value of 30,000 and an upper
limit of 40000. All variables are continuous. Don't round to integer values.
Use 1000 iterations and find the mean and the 90 th percentile of the profit distribution and the
probability of a loss. Include the histogram of Profit in your response.
Problem 4:
The table below gives the activity duration and precedence relationships for a small project
consisting of six activities. Also shown is the cost per day of crashing each activity and the
maximum number of days that each activity may be crashed.
Activity Predecessor Normal Time
(days)
Maximum
Crashing (days)
$/day
1 _ 9 5 5000
2 _ 7 3 6000
3 1 5 3 4000
4 1,2 8 4 2000
5 3 6 3 3000
6 4,5 9 5 9000
1) Determine which activities should be crashed, and by how much, to complete the
project in 22 days.
2) Suppose there is no specific completion time but that there is a payment of $5000 for
each day that the project duration is reduced below the normal completion time.
Determine the optimum number of days to complete the project and which activities
would be crashed and by how many days.
Problem 5:
A TV manufacturing company uses speakers at the rate of 8000/mo. When it places an order for
speakers it incurs a fixed cost of $1200. The monthly interest rate for keeping a speaker in stock is
assessed at 1%/mo. The cost of the speaker depends on the order size. If less than 1000 speakers are
ordered the cost is $11 each. When the order size is between 1000 and 10,000 the cost is $10.50/unit.
For order sizes between 10,000 and 30,000 the cost is $10 per unit. For order quantities between 30,000
and 80,000 the cost drops to $9.50. Beyond 80,000 the cost is $9.25. Determine the optimum order size
and time between orders if shortages are not allowed.
