Study Notes
Introduction to Engineering Economy
- Engineering Economy is a systematic analysis and evaluation of factors influencing the economic success of engineering projects, leading to a recommendation for optimal capital utilization.
Engineering Economics And Design Process
- Engineering Economics utilizes a structured procedure and mathematical models for analyzing economic situations involving multiple alternatives.
- The design process involves a series of steps to analyze engineering economic problems:
- Problem recognition, formulation, and evaluation: Identifying the problem, defining the desired future outcome, and outlining goals and objectives for a solution.
- Development of feasible alternatives: Applying the first principle of Engineering Economy, this involves generating a comprehensive list of potential solutions.
- Techniques for generating alternatives include:
- Classic Brainstorming: A widely used technique where criticism is discouraged, freewheeling is encouraged, quantity is prioritized, and combination and improvement are actively sought.
- Nominal Group Technique (NGT): A structured group meeting format that focuses on: - Individual silent idea generation. - Individual round-robin feedback and idea recording. - Group clarification of ideas. - Individual voting and ranking to prioritize ideas. - Discussion of group consensus results.
- Techniques for generating alternatives include:
- Development of outcomes and cash flows for each alternative: Identifying potential outcomes for each alternative and quantifying them (applying principles 2, 3, and 4).
- Emphasize differences in outcomes between alternatives, using consistent perspectives and common units of measure for comparison.
- Selection of criteria: Establishing criteria for evaluating alternatives based on consistent viewpoints and considering relevant criteria like cost, quality, quantity, performance, etc.
- Analysis and comparison of alternatives: Evaluating alternatives using the selected criteria.
- Selection of the preferred alternative: Choosing the preferred alternative while explicitly stating associated risks and uncertainties.
- Performance monitoring and post-evaluation of results: Assessing whether the chosen alternative achieved the objectives and identifying areas for improvement.
Sample Problem: Ordering Pizza
- Problem: Hunger among friends, desire to order pizza.
- Alternatives:
- Shakey's Hawaiian Square Pizza: 30-inch, 1 and ¼ inch thick crust, P359.00 + P100.00 delivery.
- Greenwich Hawaiian Round Pizza: 30-inch diameter, 1 and ¾ inch thick crust, P399.00 + P100.00 delivery.
- Analysis:
- Applying Principle 4 (common unit of measure), use unit: Peso per unit of volume.
- Cost Comparisons:
- Shakey's: P359.00 + P100.00 = P459.00
- Greenwich: P399.00 + P100.00 = P499.00
- Decision: Alternative 2 (Greenwich) is more economical.
- Uncertainties (Principle 6):
- Taste and quality
- Delivery time
- Evaluation (Principle 7):
- Assess if the chosen pizza tastes good and if the delivery was on time.
