Question 1
Faraway Inc. is considering a research and development project that will
cost \$5 million. Profit projections appear promising, but Farawayâ€™s CEO is
concerned because the probability that the R&D project will be successful
is 0.5. Furthermore, the CEO knows that even if the project is successful it
will require the company to build a new production facility at a cost of \$20
million in order to manufacture the product. If the facility is built,
uncertainty remains about the demand and therefore the profit that will be
realised. The expected revenues and probabilities associated with possible
demand levels are as follows:
Demand Probability Revenue
(\$ million)
High 0.5 59
Medium 0.3 45
Low 0.2 35
Another option is that, if the R&D project is successful, the company could
sell the rights to the product for \$25 million; under this option, the
company would not need to build the production facility.
a) Design a decision tree for this problem.
b) Solve the tree and make a recommendation to the CEO of Faraway.
decreased to 0.2 and the probability of low demand increased to 0.5?
Explain.
Question 2
Two telecommunications companies, Teltus and Opstra, compete with
each other for market share. In planning marketing strategy for the coming
year each company will select one of three strategies designed to gain
market share. The three strategies are as follows:
B) Provide quantity discounts
C) Reduce contract-length requirements
The payoff table for Teltus (in terms of percentage changes in market
share) is:
Teltus Strategy Opstra strategy
A B C
A 4 3 2
B -1 4 1
C 5 -2 5
Determine the following (explain how you arrived at each
result):
a) The optimal strategy for Teltus.
b) The optimal strategy for Optsra.
c) The value of the game.
Question 3
The Mixtech Company is going to introduce one of three possible new
products: a Getwid, a Humgun or a Notnim. The market conditions will
determine the profit or loss the company experiences as shown in the
following payoff table.
Market conditions
Favourable Stable Unfavourable
Probability 0.15 0.65 0.20
Getwid 120,000 70,000 -30,000
Humgun 60,000 40,000 20,000
Notnim 35,000 30,000 30,000
a) Determine the expected value for each decision and select the best one.
b) Develop an opportunity loss (regret) table and compute the expected
opportunity loss for each product.
c) Determine how much the firm would be willing to pay a market research
firm to gain better information about future market conditions.
