Generating and Constraining Variants in Parametric Design

Possible Adoptions and Extensions of Horst Rittel’s Design-Methodological Research in Computational Design

Integrative design methods for complex architectural projects need to be based on systematic and adaptable models in order to be able to act according to specific design intent and react to changing conditions during the design and planning phases. Changing conditions result from an argumentative process between the various stakeholders during the design phases and contextual information. Complex design processes are constructed through mechanisms for generating, constraining and selecting variants, encapsulated by computationally defining arguments, criteria, constraints, parameters and their variables. In this way there is a considerable and potentially instrumental overlap between contemporary computational parametric design processes and earlier research on design methodology, in particular the work of Horst Rittel. During the 1970s and 1980s Rittel, one of the most prominent figures in this field, conducted indepth research on the decision-making process of architectural design. This research project investigates the relation and possible ramifications for today’s developments of integrative parametric design processes between Rittel’s design methodology and contemporary computational design.
