Since the seminal paper by Hotelling (1929) the principle of minimum differentiation has been accepted as one of the basic principles of theoretical and mathematical approaches to competitive location problems. However, despite its popularity, the principle is not robust: if the assumptions...

In this paper we present a shape representation at the symbolic level that extends the properties of shape in two and three dimensions by use of the same formalism. This representation is based on the concept of infinite maximal lines and planes. Constraints on their properties are used to...

In this paper we accept the performance problem as given, including the theoretical analysis of it made elsewhere. Here we report empirical research into whether people making strategic plans were aware of this performance problem and, if so, what they did to improve the performance of their...

Most people value and enjoy the benefits that the use of their own car brings to their quality of life. These benefits are reflected in the increases in travel, the use of more resources, and the production of more pollution. However, this situation is not sustainable. In this paper the author...

New developments in computation based on cellular automata (CA), which are finding widespread application in simulating evolution, are beginning to suggest that science is not simply about the study of actual phenomena but about potential or possible phenomena. This notion is central to design...

As an alternative to conventional monodirectional simulation tools, we introduce a preference-based performance-driven tool to generate computationally single-room designs based on requirements of daylight availability and distribution. To extend the applicability of this tool beyond single-room...
