QUESTION 1. What are two types of uncertainty we have defined in our course, and which one is most important to the practice of decision analysis? Explain. QUESTION 2. Because sensitivity analysis is such a demanding process, it is rarely done for all possible alternatives in any given decision context. In addition, Clemen and Reilly describe sensitivity analysis as a "built-in irony": they write that [remaining alternatives] "being difficult to choose from, they probably are not too different in expected value." For complex decision situations, describe how dominance criteria, sensitivity analysis, and value of information might be used to select from among your alternatives and refine your thinking about the decision context. Be sure to discuss the complementary role of dominance criteria and sensitivity analysis in leading the decision maker to construct a requisite model which renders a clear choice.
