A specific approach is described to the elaboration of a new-generation three-dimensional image-synthesis system built around a language taken as the main communication medium between the different modules of the system. The outlines of the subject are deliberately limited to the...

A case study is reported of the design, implementation, and evaluation of a knowledge-based decision support system, XPLanner. XPLanner integrates an expert system with optimization modeling technique, database management system, and interactive user interface to create a comprehensive decision...

Working within the location covering framework, the authors develop a mathematical programming approach for siting facilities which maximizes the extent of spatial market coverage, while maintaining threshold-demand levels for individual facility sites. The model, known as McTHRESH, can be...

This is the second of two papers to report on an analysis of housing form, drawing on a computerised database of a sample of British house plans. The principal topological characteristics of the plans (access, adjacency) are summarised and discussed, and a taxonomy of plan forms is presented,...
