Q4. This question relates to the Zooter Example discussed in Sessions 1 and 2, and tests your understanding of the algebraic model formulation. You can answer it without using Excel. Only use Excel if you cannot answer this question otherwise.

In a typical week, Zooter has ample warehouse capacity to store the scooters it manufactures. The company has just learned that one of its warehouses got flooded and will not be available to store scooters produced in the coming week. As a result, Zooter projects that its total storage capacity for the coming week will be limited to 8000 cubic feet. One unit of Razor model requires 6 cubic feet of storage capacity and one unit of Navajo model requires 7 cubic feet of storage capacity. In terms of decision variables R and N, which algebraic expression represents the constraint “the total storage capacity required for the next week’s production cannot exceed 8000 cubic feet”?

  • 6*R + 7*N ≥ 8000
  • 6*R + 7*N ≤ 8000

Q10. For this question, consider the following decision problem. A decision maker must choose one of three actions: A, B, or C. The outcome of each action is uncertain, as follows.

  • If action A is chosen, there are two possible outcomes. With probability 0.2 the reward is 100, and with probability 0.8 the reward is 400.
  • If action B is chosen, there are three possible outcomes. With probability 0.25 the reward is 200, with probability 0.5 the reward is 250, and with probability 0.25 the reward is 300.
  • If action C is chosen, there are two possible outcomes. With probability 0.8 the reward is 0, and with probability 0.2 the reward is 500.

To answer questions 7-10, below, draw and then analyze a decision tree that corresponds to the decision-maker’s problem, above.

What is the expected value of the expected-value-maximizing decision?

  • 300
  • 340
  • 200
  • 100
  • 250
