1
Requirements and Optimization

• Unit 3 Lesson 2

2
Optimize

1. To exploit fully
2. To position an economic entity such that it
   functions as well as possible given constraints
   that it might be subject to.
3. To make something function at its best or most
   effective, or use something to its best
   advantage.
4. To make as perfect or effective as possible.
5. To make the most or best of (a particular
   situation or opportunity, etc.

3
Requirements

• Are the parameters placed on the development of a
  product or system.
• Requirements include safety needs, the physical
  laws that will limit the development of an idea,
  the available resources, and the cultural norms.

4
Criteria and Constraints

• Criteria identify the desired elements and
  features of a product or system.
• Constraints involve limitations on a design.

5
Requirements Vs Conflicts

• Because requirements can compete with one
  another, accommodating one often results in
  conflicts with others.
• Because of these conflicts, perfect designs
  simply do not exist.

6
Efficiency

• Efficiency specifies how well the given product
  or system performs and how close that performance
  is to the ideal or optimal performance.

7
Optimization

• Optimization is a process used to make a design
  as effective or functional as possible within the
  given criteria and constraints.
• Optimization can ensure that a product or system
  is as efficient as possible.
• To systematically seek an optimum design
  solution, designers use experience, education,
  established design principles, creative
  intuition, imagination, and culturally specific
  requirements.

8
models

• used to test ideas and to make changes to a
  design.
• There are several types of models used to test
  and refine designs including
• physical models
• mathematical models
• computer models.

9
Computer Model

• A computer simulation or a computer model is a
  computer program that attempts to simulate a
  physical model of a particular system.
• Computer simulations have become a useful part of
  the process of technological design.

10
computer simulation program

• Students will use a computer simulation program
  to
• Optimize the design of a truss bridge that will
  carry a two-lane highway across a river valley.
