Decision Support Quiz — Industrial Engineering

Question 1

In a complex multi-objective optimization problem for an industrial system, an engineer observes that improving one objective (e.g., minimizing cost) significantly degrades another objective (e.g., maximizing quality). This scenario best exemplifies which concept in decision analysis?

Question 2

An industrial engineer is tasked with selecting the optimal location for a new manufacturing plant. The decision involves multiple criteria, including initial investment cost, proximity to raw materials, labor availability, and environmental impact. To systematically evaluate and rank potential locations, considering both quantitative and qualitative factors, which advanced multi-criteria decision-making (MCDM) technique would be most appropriate for structuring the problem and deriving a preference order based on subjective judgments and objective data?

Question 3

When developing a real-time dashboard for an industrial production line, the primary goal is to enable immediate comprehension of critical operational anomalies and facilitate rapid executive decision-making. Which visualization principle is most crucial to achieve this objective?

Question 4

An industrial engineer is designing a decision support system for optimizing a supply chain network. The system needs to account for various factors such as transportation costs, warehouse capacities, and customer demand, all of which are subject to inherent uncertainties. Which type of model within the DSS would be most effective for simulating different scenarios and assessing the robustness of potential solutions under these uncertain conditions?

Question 5

Consider a decision problem where an industrial engineer must choose between two mutually exclusive projects, Project A and Project B. Project A has an initial cost of $$ \$100,000 $ and is expected to generate annual net cash flows of $ \$30,000 $ for 5 years. Project B has an initial cost of $ \$120,000 $ and is expected to generate annual net cash flows of $ \$35,000 $$ for 5 years. Assuming a discount rate of 10\%, which project should be chosen based on the Net Present Value (NPV) criterion?\To calculate the NPV, the formula is:$$ NPV = \sum_{t=1}^{n} \frac{CF_t}{(1+r)^t} - C_0 $\where:\\$ CF_t $ = Net cash flow at time t\\$ r $ = Discount rate\\$ C_0 $ = Initial cost\\$ n $$ = Number of periods
