BUS461:Decision Modeling & Analysis Assignment1 - Uncertainty
Week 2 - Assignment
Uncertainty
Read Case 6.3: Electronic Timing System for Olympics on pages 275-276 of the textbook. For this
assignment, you will assess and use the correct support tool to develop a decision tree as described in
Part “a” of Case 6.3. Analyze and apply the best decision making process to provide answers and brief
explanations for parts “a”, “b”, “c”, and “d”. The answers and explanations can be placed in the same
Excel document as the decision tree.
a. Develop a decision tree that can be used to solve Chang’s problem. You can assume in this
part of the problem that she is using EMV (of her net profit) as a decision criterion. Build the
tree so that she can enter any values for p1, p2, and p3 (in input cells) and automatically see
her optimal EMV and optimal strategy from the tree.
b. If p2 = 0.8 and p3 = 0.1, what value of p1 makes Chang indifferent between abandoning the
project and going ahead with it?
c. How much would Chang benefit if she knew for certain that the Olympic organization would
guarantee her the contract? (This guarantee would be in force only if she were successful in
developing the product.) Assume p1 = 0.4, p2 = 0.8, and p3 = 0.1
d. Suppose now that this is a relatively big project for Chang. Therefore, she decides to use
expected utility as her criterion, with an exponential utility function. Using some trial and error,
see which risk tolerance changes her initial decision from “go ahead” to “abandon” when p1 =
0.4, p2 = 0.8, and p3 = 0.1.
In your Excel document,
1. Develop a decision tree using the most appropriate support tool as described in Part a.
2. Calculate the value of p1 as described in Part b. Show calculations.
3. Calculate the possible profit using the most appropriate support tool as described in Part c.
Show calculations.
4. Calculate risk tolerance as described in Part d. Show calculations.
