Answer to Question 1

d
RATIONALE: An input to a simulation model that is selected by the decision maker is known as a controllable input.

Answer to Question 2

b
RATIONALE: A simulation experiment produces a distribution of output values that correspond to the randomly generated values of the uncertain input variables. This probability distribution of the output values describes the range of possible outcomes, as well as the relative likelihood of each outcome.
