Examples? •  Basic idea: Mapping view point. –  What is mapping in mathema6cs? •  Design space: What are the different domains and spaces in math. terms in design? •  •  •  •  •  •  •  •  Axiom 1: Independence Axiom Axiom 2: Informa6on Axiom What does Axiom 1 mean mathema6cally? What are the different cases in design in terms of Axiom 1? Corollary I: Decouple Corollary III: Integrate Corollary IV: Standard & Exchangeable; Corollary V: Symmetry Review: •  •  •  •  Decision Making (Chapter 7) Decision making is everywhere; Opera6on research First, psychological aspects—Why are they there? How people deal with DM? What are the different paXerns? •  Basic ingredients in decision making? Decision Theory •  What are the basic elements (in terms of Design?) •  What are the different types of D.M. models? Examples of Different Decision Types •  Select material to resist road salt corrosion in an automo6ve fender •  Case I Examples of Different Decision Types: Case II •  Select material to resist road salt corrosion in an automo6ve fender •  Case II Case III: Maximin Rule, Maximax Rule, and Combined U6lity Theory •  Mo6va6on: How to determine the u6lity fun.? •  Basic defini6ons: –  –  –  –  Value Performance U6lity Marginal U6lity •  U6lity –Func6on U6lity Func6on •  When it becomes challenging? •  Example: •  Two criteria: Expected U6lity Analysis •  •  •  •  •  •  Key: A]tude  D.M. process Goal: Challenge: How to determine U(x)? Risk vs. Gain? Example: Which to prefer? Scenario I: •  Scenario II: How to Apply in Design? •  Convert •  Two common types of U(x): •  Design  Mul6a]tude U(x).
