title	ROOS1 -- Version One of a Generative Expert System for the Design of Building Layouts
source	17 p. : ill. Pittsburgh: Engineering Design Research Center, Carnegie Mellon University, September, 1986
summary	ROOS1 is a generative expert system for the design of building layouts. The system is intended to complement human designers' performance through (a) its ability to systematically search for alternative solutions with promising trade-offs; and (b) its ability to take a broad range of design concerns into account. Work on the system provides insights into the applicability of Artificial Intelligence techniques to space planning and building design in general. The system is based on a general generate-and-test paradigm. Its main components are a generator, a tester and a control strategy (which is to be expanded later into a genuine planner). The generator is restricted to the allocation of rectangles. The spatial relations above, below, to the left and the right are defined for pairs of objects in a layout and serve as basic design variables which define differences between solutions and govern the enumeration of alternatives. Within the class of layouts it is able to produce, the generator is completely general and able to generate all realizable sets of spatial relations for a given number of objects. In contrast, the tester is domain-specific and incorporates knowledge about the quality of layouts in a specific domain. The system can be applied to various domains by running it with the appropriate tester and, possibly, the appropriate control strategy. The control strategy itself mediates between planner and tester and, when expanded into a planner, is able to streamline the search for alternatives. The system will go through a sequence of versions with increasing complexity. Each version will have a conceptually clean and clear architecture, and it is the authors' intention to evaluate each architecture explicitly in terms of its promises and limitations with respect to various domains. The first of these versions is described in the present paper

title	The Computer in the Design Studio. Ideas and Exercises that Go Beyond Automated Drafting
doi	https://doi.org/10.52842/conf.acadia.1986.055

summary	The present use of computers in the design studio focusses on automating routine tasks and on increasing drawing productivity. We assume that the impact of computers in design can be more profound and present a series of exercises for two contrasting design studios that build on our teaching and computing experience. 'Me first studio uses the computer as a design evaluation tool. The second studio demonstrates the use of computers for simple design generation tasks. In both cases, a very general and important educational objective is pursued, and computers become an integral part of the exercise.

title	On the Representation and Generation of Loosely-Packed Arrangements of Rectangles
source	33 p. : ill Pittsburgh: Engineering Design Research Center, CMU, September, 1986. includes bibliography.
summary	Several computer programs that enumerate rectangular dissections as solutions to certain layout problems have established a distinct paradigm for dealing with the crucial theoretical issues involved. The present paper suggests an extension of the paradigm to include `loosely-packed arrangements of rectangles,' which are of wider applicability in an architectural context. The paper introduces orthogonal structures to represent these arrangements and establishes the conditions of well-formedness for these structures. It presents a grammar to enumerate orthogonal structures and suggests that best use is made of the grammar if it is incorporated into a generative expert system, able to serve as a vehicle to discover, encode and utilize a broad range of constraints and criteria in the generation of layout alternatives

title	The Role of Shape Grammars in the Analysis and Creation of Designs
source	New York: John Wiley & Sons, 1986. pp. 213-244 : ill. includes bibliography
summary	The paper gives an informal introduction to the shape grammar formalism. It presents results form a case study in which this formalism was applied to a realistic problem in order to convey the flavor of work with such grammars, to demonstrate its advantages and to show that our familiarity with this formalism has now progressed to a level were issues of architectural substance can be addressed. The paper concludes with the outline of a simple way to implement shape grammars by computer: it does not resolve the theoretical problems that exist for such implementations, but makes non-trivial applications like the case study possible
