Question 1
ABC Computer Company is considering submission of a bid
for a government contract to provide 10,000 specialized computers for use in
computer-aided design. There is only
one other potential bidder for this contract, Complex Computers, Inc., and the low bidder will receive the
contract. ABC's bidding decision is complicated by the fact that ABC is currently working on a new process to
manufacture the computers. If this
process works as hoped, then it may substantially lower the cost of making the computers. However, there is
some chance that the new process will actually
be more expensive than the current manufacturing process. Unfortunately, ABC
will not be able to determine the cost of the new process without actually using it to manufacture the computers. If
ABC decides to bid, it will make one of three
bids:
$9,500 per computer, $8,500 per computer, or $7,500 per
computer. Complex Computers is certain
to bid, and it is equally likely
that Complex will bid $10,000,
$9,000, or $8,000 per computer. If ABC decides to bid,
then it will cost $1,000,000 to prepare
the bid due to the requirement that a prototype computer be included with the bid. This $1,000,000 will be
totally lost regardless of whether ABC wins or loses the bidding competition.
With ABC's current manufacturing process, it is certain to cost $8,000 per computer to make each computer. With the
proposed new manufacturing process,
there is a 0.25 probability that the manufacturing cost will be
$5,000 per computer and a 0.50 probability that the cost
will be $7,500 per computer. Unfortunately, there is also a
0.25 probability that the cost will be $8,500
per computer.
Develop a decision tree and EVM. Should ABC Computer
Company submit a bid, and if so, what should they bid per computer?
B ayes` Rule: If an athlete is tested for a certain type of drug usage
(steroids, say),
then the test result is either positive or negative.
However, these tests are never perfect.
Some athletes who are drug-free test positive and some who are drug users test
negative. We assume that 5% of all athletes use drugs, 3% of all test on drug-
free athletes yield false positives and 7% of all test on drug users yield false negatives. Suppose a typical athlete
is tested. If this athletes tests positive, are we sure that he is a
drug user? If he tests negative, are we sure, he does not use drugs?
Assume, D and ND denote that a randomly chosen athlete
is or is not a drug user, and let T+ and T- indicate a positive or negative
test results. (The outcomes D and ND corresponds to A and Not A and either T+
or T- corresponds to B in Bayes` Rule).

Question 2:
In Week 5 and 6(using the Decision Making Examples
manual), you developed a Optimisation
model for Pigskin company, producing
footballs. The objective is to find
the production schedule that meets demand on time and minimises total production costs and inventory
holdings costs. Now, use the fully developed spreadsheet (after completing the
manual) and perform below changes on the model,
1.
Modify the Pigskin spreadsheet
model so that expect for month 6, demand need
not be met on time. The only requirement is that all demand be met eventually
by the end of month 6. How does this change the optimal production schedule? How does it change the optimal
total cost?
2.
Modify the Pigskin spreadsheet
model so that demand in any of the first 5 months must be met no later than a
month late, whereas demand in month 6 must be met on time. For example, the
demand in month 3 can be met partly in
month 3 and partly in month 4. How does this change the optimal production schedule? How does it change the optimal
total cost?
3.
Modify the Pigskin spreadsheet
model in the following way. Assume that the
timing of demand and production are such that only 70% of the production
in a given month can be used to satisfy the demand in that month. The other 30%
occurs too late in that month and must be carried as inventory to help satisfy demand in later months. How
does this change the optimal production schedule? How does it changes the
optimal total cost?

Question 3:
GulfGulf is a small family-run company in the United
Arab Emirate. It manufactures golfing equipment aimed at the increasing demand,
primarily from tourists coming for golfing
holidays in the gulf region. The company has decided to manufacture two new
products: a medium-priced golf bag and a more up-market, expensive golf bag. The company`s products are priced in
$ given its international customer base. The
company`s distributor is enthusiastic about the new product line and has
agreed to buy all the golf bag the company produces over the next three months.
After a thorough investigation of
the steps involved in manufacturing a golf bag,
management determined that each golf bag produced will require the
following four operations:
1.
Cutting and dyeing the material needed
2.
Sewing
3.
Finishing (inserting, umbrella holder, club
separators, etc.)
4.

After studying departmental workload projections, the
director of manufacturing estimates
that 630 hours for Cutting and dyeing, 600 hours for sewing, 708 hours for finishing and 135 hours for inspection
and packing will be available for the production of golf bags during the next
three months. Accounts department arrives at prices for both bags that will
result in a profit contribution of $10 for every standard bag and $9 for every deluxe bag produced.
1.
How many of the two types of golf
bag should it manufacture in order to maximize profit contribution? Use a
graph paper to find the feasible region and to find the maximum number of standard
and deluxe bags to produce?
2.
Produce an Excel model and use Solver to replicate
the hand calculation.

Question 4
Refer to the Table 1 and do the following:
1. Calculate the
Expected activity time,
2.
Develop the Network diagram using the Expected
activity time and use PERT Analysis
to know the mean and Sd of the project.
3.
Based on these estimates and the resultant expected
project duration of 44 weeks. The
executive committee wants to know what is the probability of completing the
project before a scheduled time of 46 weeks?
4. What is the
probability that the project lasts more than 46 weeks?
5.
What would be the completion time under which for
the project has 85% probability of
completing?
6.
How do you measure project risk exposure? Explain
and propose ways to reduce the
project risk exposure.
