KI for Design of Complex Systems KORER ADVANCED INSTITUTE CF SCIEHCE AHD TECHHCLOOY Generic c Axioms of Design Thinking Good Design Thinking must consist of an Ideality concept The design Ideality prescribes the most "ideal"state of a design i.e.,What could be the most ideal (not necessarily most practical)design result? Design thinking should guide designers move toward this Ideality Although the design Ideality is not always achievable in design practice,due to resource constraints,it does point to the right direction for designers to make better design decisions The design Ideality must be axiomatic and domain-independent Axioms cannot be proven deductively,but have no counterexamples An Ideality Maxim:the simplest design is the most ideal design This Maxim can be realized by different axioms in various design theories Axiomatic Design:an "uncoupled design"is the simplest(most ideal)design AD suggests ways to manage dependencies to achieve the design Ideality TRIZ:the simplest(most ideal)design is no design(FR without DP,contradiction) TRIZ suggests ways to resolve contradictions to achieve the design Ideality These Axioms are used to select good design concepts at early stages Axiomatic Design:the Independence Axiom,the Information Axiom TRIZ:Inventive/Separation Principles for system/physical contradictions Fall 2007 Stephen Lu KAIST Study Design Thinking to Make Design of Complex Systems Simple 20Generic Axioms of Design Thinking of Design Thinking Good Design Thinking must consist of an Ideality concept Th d i Id lit ib th t “id l” t t f d i ine „ The design Ideality prescribes the most “ideal” state of a design Š i.e., What could be the most ideal (not necessarily most practical) design result? „ Design thinking should guide designers move toward this Ideality eŠ Although the design Ideality is not always achievable in design practice, due to cture 6 Outl Although the design Ideality is not always achievable in design practice, due to resource constraints, it does point to the right direction for designers to make better design decisions The design Ideality must be axiomatic and domain-independent „ Axioms cannot be proven deductively but have no counterexamples L e Axioms cannot be proven deductively, but have no counterexamples An Ideality Maxim: the simplest design is the most ideal design „ This Maxim can be realized by different axioms in various design theories Š Axiomatic Design: an “uncoup g p( ) g led design” is the simplest (most ideal) design „ AD suggests ways to manage dependencies to achieve the design Ideality Š TRIZ: the simplest (most ideal) design is no design (FR without DP, contradiction) „ TRIZ suggests ways to resolve contradictions to achieve the design Ideality These Axioms are used to select good design concepts at early stages Fall 2007 © Stephen Lu @ KAIST [ Study Design Thinking to Make Design of Complex Systems Simple ] 20 These Axioms are used to select good design concepts at early stages „ Axiomatic Design: the Independence Axiom, the Information Axiom „ TRIZ: Inventive/Separation Principles for system/physical contradictions
