  • The formal mathematical optimization problem statement is:
    • minimize f(x): objective function
    • subject to: h(x) = 0, i = 1,…, m₁ (equality constraints)
    •        g(x) ≤ 0, j = 1,…, m₂ (inequality constraints)
      
    • and x ∈ X ⊂ Rⁿ (design variables)

Introduction to Engineering Design Optimization

  • A methodology for finding optimal designs
  • Involves stages like: -Defining variables and objectives -Defining constraints -Finding feasible region -Optimization process

Design Versus Modeling

  • Design is generating the function or shape idea
  • Modeling is bringing the design to life, application of scientific idea to everyday life
  • Difference is like the difference between science and engineering

Effectiveness & Efficiency

  • Effectiveness: Doing the right things (achieving goals)
  • Efficiency: Doing things right (using resources well)
  • Tradeoffs exist meaning achieving both at the same time is not always possible
  • They are important for businesses and personal goals

Technology in Efficiency and Effectiveness

  • Technology can enhance efficiency through automation, reducing time and cost while working more productively.
  • Software applications can enhance efficiency and effectiveness by automating manual tasks, thereby freeing up employees to focus on value-added activities.
  • Tools like Agile methodology (e.g., Scrum) are crucial for effectiveness in software development (by being more adaptable and responsive to customers).

Importance Questions

  • How can technology enhance effectiveness? (answer: automation)
  • How can technology enhance efficiency?
  • Are effectiveness and efficiency related to optimization?
  • Can efficiency and effectiveness relate to human and machine use?
