9.4. Conclusion#
The illustrative examples show how design problems in the domain of architecture and urban planning can be solved using the preference-based design methodology. We stress that the process typically involves 2 cycles:
the technical cycle - which is mainly about the creation and verification of the mathematical model
the social cycle - which is mainly about the use and validation of the model.
To prevent confusion about verification and validation:
Verification is related to the question: did we build the model right?
Validation is related to the question: did we build the right model?
