Complexity



Complexity – nobody knows what it is!



Complexity – nobody knows what it is!

but everyone knows about

self-organising systems

evolutionary & cooperative processes

emergence

networks & distributed control

scaling effects



Design



Design – everybody knows what that is!

the act of working out the form of something (as by making a sketch or outline or plan);

www.cogsci.princeton.edu/cgi-bin/webwn2.1



Design is everywhere – and that’s why looking for a definition may not help you to grasp what it is


Why is CAD lousy for sketching & early stages of design?




computer representation not rich enough!





geometry and arithmetic are great

… but design uses other constructs





geometry and arithmetic are great

… but design uses other constructs

how to get these inside computer?



Design is about relationships between things

Graphs are not rich enough

3 binary relations ≠ one 3-ary relation



From Links to Multidimensional Polyhedra

University of Lancaster - Seminar 21st April 2004Binary relation 3-ary relation 4-ary relation



1-simplex 2-simplex 3-simplex 4-simplex

2-vertices 3-vertices 4-vertices 5-vertices

The generality is n-ary relations – not just links

Planning involves changing relations



Planning involves changing relations

Designers as scientists

If a designer creates a completely new system, they are the sole possessors of knowledge about that system.





The design process involves building a language and a science of the synthetic system.





The design process involves building a language and a science of the synthetic system.

Involves hypotheses, deduction, prediction, experiments, testing hypothesis.



Conclusions

Everything is multi-dimensional



Conclusions


Need multi-dimensional Q-analysis - not just graphs



Conclusions



Design involves building multi-level languages



Conclusions
