Abstract
Specific examples of how `soft' architectual design can be formalized and made available to knowledge-based design support systems are scare in the literature. In this paper such an example is presented in some detail. In a context of design of networks of foothpaths, streets, or the like for pedestrian traffic, two particular design concepts are studied: `concentration of pedestrians' and `smoothness of walking lines'. The concepts are put to work in a hypothetical design, and on that background their possible representation in Horn clause logic is outlined, and computational aspects of the representation are discussed.
