Presentation Transcript

  1. Chapter 2Knowledge need to know before start a project • Method of generating the concept • Method of decisionmaking • Review the worth of a project • Communication methods

  2. Methods of generating concepts • Brainstorming as a source of ideas • Using 6-3-5 method as a source of ideas • The use of analogies in design • Finding ideas in reference books and trade journal • using expert to help generate concept

  3. The individual designer: A model of human information procession

  4. Type of memory Type of knowledge • General knowledge • Domain-specific knowledge • Procedure knowledge • Short term memory • Long term memory

  5. Analogy • Umbrella VS. removal of urinary calculi

  6. Nature system Velcro Fastener

  7. Methods of decision making Decision matrix • Step 1: choose the criteria for comparison. • Step 2: Develop Relative importance weightings • Step 3: Select Relative Importance Weightings • Step 4: Evaluate Alternatives . • Step 5 Compute Satisfaction

  8. Decision matrix

  9. Example: Using the decision matrix:

  10. Evaluation Based on advanced Decision matrix • Step 1: choose the criteria for comparison. • Step 2: Develop Relative importance weightings • Step 3: Select Relative Importance Weightings • Step 4: Evaluate Alternatives . • Step 5 Compute Satisfaction Satisfaction =Σ(belief*importance weighting)

  11. Believe Belief=confidence placed on an alternative’s ability to meet a target set by a criterion, requirement, or specification, base on current knowledge.

  12. Belief=p(k)*p(c)+(1-p(k))*(1-p(c))

  13. Example

  14. Making a portfolio decision • SA: strongly agree A; Agree N: neutral D: disagree SD: Strongly disagree • VC: Very certain C: Certain N: Neutral U: uncertain VU: very uncertain

  15. Review the worth of a projectBefore beginning a project • Is there a good potential return on investment? • Does the new product or improvement fit the company image? • Does it fit the distribution channels? • Is there sufficient production capacity in-house or with known vendors? • What will the project cost?

  16. Communication methods • Design Record-design note book • Documents communicating with management-design reviews • Documents communicating the final design -drawing of components and assemblies -written documentation to guide manufacturing, assembly, inspection, installation, maintenance, retirement and quality control
