Understanding Engineering Economy
Engineering economy is a sub-discipline of engineering that focuses on the evaluation of the economic viability of projects, technologies, and processes. This field encompasses various analytical techniques, financial assessments, and decision-making strategies essential for engineers and managers.
Key Principles of Engineering Economy
1. Time Value of Money: Understanding how the value of money changes over time due to interest rates, inflation, and investment opportunities is crucial. Key concepts include:
- Present Worth (PW)
- Future Worth (FW)
- Annual Worth (AW)
- Net Present Value (NPV)
2. Cost Analysis: Engineers must analyze all costs associated with a project, including:
- Fixed Costs: Costs that do not change with the level of production or project execution.
- Variable Costs: Costs that vary directly with the level of production.
- Life Cycle Costs: Total cost of ownership over the life of an asset.
3. Decision-Making Techniques: Various methods help in making informed decisions based on economic analysis, such as:
- Payback Period
- Internal Rate of Return (IRR)
- Benefit-Cost Ratio (BCR)
4. Risk and Uncertainty Analysis: Understanding the risks associated with projects and how uncertainty affects economic outcomes is vital. Techniques include sensitivity analysis and scenario planning.
