QUESTIONS AND COMPLETE ANSWERS
◉ What is the purpose of using decision trees in engineering
economics?
Answer: To visualize and analyze the potential outcomes of different
decision paths.
◉ What is the relationship between inflation and price change in
engineering economics?
Answer: Inflation affects the purchasing power of money and must
be considered in cost estimations.
◉ What is the significance of replacement analysis in engineering
economics?
Answer: It helps determine the optimal time to replace equipment
or assets based on cost and efficiency.

,◉ What is engineering economy?
Answer: A collection of techniques that simplify comparisons of
alternatives on an economic basis.
◉ What does engineering economy NOT do?
Answer: It does not determine what the alternatives are; it begins
after alternatives have been identified.
◉ What is the primary criterion for selecting alternatives in
engineering economy?
Answer: Economics is the sole criterion, but real-world decisions
often include other factors.

Answer: 1) Is there a need for the project? 2) Can it be delayed? 3) Is
this the best alternative?
◉ What is multiple attribute analysis?
Answer: The inclusion of factors besides economics in the decision-
making process.

energy sources?
, Answer: Safety, air pollution, public acceptance, water demand,
waste disposal, and global warming.
◉ What does the DICE model analyze?
Answer: It evaluates CO2 emissions, climate impact, and economic
factors.

Answer: 1) Define problem 2) Choose objectives 3) Collect data 4)
Identify alternatives 5) Select criteria 6) Construct model 7) Predict
outcomes 8) Choose best alternative 9) Audit results.
◉ What distinguishes simple, intermediate, and complex problems?
Answer: Simple problems are easily solved, intermediate require
organization, and complex involve economic, political, social, and
environmental elements.
◉ What is the focus of microeconomics?
Answer: The decisions of individual units, such as businesses.
