A fundamental problem in editing shapes is the recognition of partial shapes in a drawing to which changes are to be made. In this paper the possibility of using shape rules as a mechanism for effecting such changes is explored. Shape rules represent spatial relationships between two shapes α...

It is argued here that we must establish a demonstrably sound, comprehensive, rigorously formalized theoretical foundation upon which to base practical computer-aided architectural design software-development efforts, and a general approach to this task is suggested.First, the basic types of...

This paper is an exploration of the way the new political economy approaches in the social sciences can be developed to provide a more robust knowledge-base for local land-use planning. Consideration is given to present deficiencies in our understanding and their consequences. There then follows...

Personal construct theory is introduced as an all-embracing philosophy which provides a consistent framework for integrating different notions about the planning process. The implication is that 'man-the-planner' does not necessarily have constructs which are better, more accurate, or more...

The automated design of architectural floor plans satisfying given topological and dimensional constraints is a challenging field of research. In this paper abstraction is pointed out as an important conceptual tool of this field. A critical discussion of existing plan-design methods leads to...

A design world describes knowledge about possible designs. The characteristics of design worlds in engineering and architecture are compared. An implementation of three-dimensional shape grammars is outlined and the description of composite spatial relations which arise in generated shapes is...

The rehabilitation of large public housing projects requires the relocation of project tenants during construction. This paper formulates scheduling models for this relocation problem. A basic model for homogeneous tenant populations is studied in detail, and a promising approximation is...

This paper is a report on the structure and the operational procedure of an implementation-scheduling model (ISM) used in preparing an urban development program for a small South African city. The model is aimed at defining a yearly or a phase-based set of projects that will maximize community...
