Author: [Your Name/AI Assistant]
Subject: Engineering Economics Analysis
Reference Text: Blank, L., & Tarquin, A. (2017). Ingeniería Económica (8th ed.). McGraw-Hill.

Part 3: Real-World Complexities (Chapters 9–13)

  • Utility: Moves beyond textbook theory into realistic scenarios.
  • Key Concepts: Replacement/Retention analysis (Defender vs. Challenger), Effects of Inflation, and Taxation/Depreciation (MACRS).
  • Professional Application: Highly relevant for project managers determining when to replace aging equipment.

Capítulo 10: Efectos de la Inflación en los Proyectos

  • 10.1 Medición de la inflación (IPC, tasas inflacionarias)
  • 10.2 Tasas de interés real, inflada y de mercado
  • 10.3 Conversión de flujos de efectivo a moneda constante y corriente
  • 10.4 Análisis VP y TR con inflación

Capítulo 6: Análisis del Valor Anual Uniforme Equivalente (VA o CAUE)

  • 6.1 Concepto de valor anual (VA)
  • 6.2 Cálculo de VA para alternativas con vidas iguales y diferentes
  • 6.3 VA para activos perpetuos
  • 6.4 Comparación de alternativas por VA
  • 6.5 Ventajas del análisis VA

3. Focus on "Solved Examples"

The 8th edition has "Example" boxes throughout. Before doing homework, cover the solution, solve it yourself, then reveal the answer. This is where Blank & Tarquin excel—their examples mirror exam questions. ingenieria economica blank tarquin 8va edicion

2. Extensive Problem Sets

The 8th edition contains over 800 end-of-chapter problems. These range from basic arithmetic checks to open-ended case studies (e.g., "Should a city replace its water pipelines now or later?"). For self-learners and professors, this is an invaluable question bank.

7. Practical Application Example (From Chapter 8 Style)

Problem: A manufacturing company must decide between two machines: Part 3: Real-World Complexities (Chapters 9–13)

  • Machine X: Initial cost $50,000, annual operating cost $8,000, salvage value $5,000, life 5 years.
  • Machine Y: Initial cost $80,000, annual operating cost $5,000, salvage value $10,000, life 8 years.
  • MARR = 12% per year.

Solution using Annual Worth (AW) per Blank & Tarquin 8e:

[ AW_X = -50,000(A/P,12%,5) - 8,000 + 5,000(A/F,12%,5) ] [ = -50,000(0.27741) - 8,000 + 5,000(0.15741) = -13,870.50 - 8,000 + 787.05 = -21,083.45 ] 5) - 8

[ AW_Y = -80,000(A/P,12%,8) - 5,000 + 10,000(A/F,12%,8) ] [ = -80,000(0.20130) - 5,000 + 10,000(0.08130) = -16,104 - 5,000 + 813 = -20,291 ]

Since ( AW_Y > AW_X ) (less negative), select Machine Y. This matches the textbook’s recommendation to always use AW for different-life alternatives.
