Study Notes
Engineering Economics
- Engineering economy systematically evaluates the economic merits of proposed solutions to engineering problems.
- Solutions must demonstrate a positive balance of long-term benefits over long-term costs to be economically acceptable (affordable).
- Engineering economy simplifies comparisons of alternatives using a collection of techniques.
- An alternative is a stand-alone solution to a particular situation. Alternative considerations include purchase cost (initial cost), anticipated useful life, annual maintenance and operating costs, anticipated resale value (salvage value), and the interest rate.
Principles of Engineering Economy
- Principle 1: Develop Alternatives: Clearly define the problem and identify all potential solutions.
- Principle 2: Focus on Differences: Only consider the differences in future outcomes between alternatives, not the overall outcomes.
- Principle 3: Consistent Viewpoint: Develop prospective outcomes (economic and others) consistently from a defined perspective.
- Principle 4: Common Unit of Measure: Use a consistent unit of measurement for all relevant prospective outcomes.
- Principle 5: Consider All Relevant Criteria: Make decisions based on multiple criteria, including monetary and non-monetary factors.
- Principle 6: Make Risk and Uncertainty Explicit: Acknowledge risk and uncertainty when estimating future outcomes. Explicitly acknowledge this in analyses.
- Principle 7: Revisit Decisions: Continuously evaluate and adapt initial projections to actual results.
Cash Flow
- Cash flow refers to estimated inflows (revenues) and outflows (costs) of money.
Alternative Selection
- Every situation has at least two alternatives, including a "do-nothing" (DN) alternative. The "do-nothing" alternative represents the existing situation.
Evaluation Criteria
- Financial units (dollars or others) are typically used for economic analysis.
- The best alternative is the one with the lowest overall cost or highest overall net income.
Intangible Factors
- Non-economic or intangible factors (goodwill, convenience, morale) may influence a decision if economic differences are marginal.
Time Value of Money
- The change in the amount of money over time is a primary consideration in engineering economy.
Cost Terminology and Concepts
Fixed Costs
- Unaffected by activity level over a feasible operating range. Examples: Insurance & taxes, salaries.
Variable Costs
- Vary with output or activity level. Examples: materials & labor costs.
Direct Costs
- Easily assigned to specific outputs or work activities. Examples: materials.
Indirect Costs/Overhead Costs
- Difficult to assign to specific outputs. Examples: general supplies, maintenance.
Incremental Cost/Revenue
- The additional cost or revenue from increasing output.
Standard Costs
- Planned costs per unit; based on anticipated resource consumption.
Cash Costs
- Costs that involve a cash payment.
Book Costs
- Costs not involving cash outflow; represent the recovery of prior expenditures.
Sunk Costs
- Irreversible costs from past decisions; irrelevant for future decisions.
Opportunity Costs
- Forgone benefits from using resources in an alternative way.
Life-Cycle Cost
- Sum of all costs associated with a product, structure, system, or service throughout its life. It includes acquisition and operation phases.
