Graph-based tools for conceptual design in Civil Engineering
    This project is running at present in co-operation with RWTH Aachen (Prof. M. Nagl), University of Federal Armed Forces in Munich (Prof. A. Schuerr) and Jagiellonian University Cracow (Prof. E. Grabska). The aim of the research is to aid architects in looking for innovative conceptual solutions. To achieve that we intend to provide the user of conventional CAD-system with additional tools that enable him or her to reason at the level of functionality and topology of the designed building. The domain knowledge is coded in the form of graph grammar and made accessible through the system PROGRESS developed in Aachen. This grammar allows the system to check whether the solutions proposed by the architect fulfill all necessary constraints. Upon request, our system will also be able to generate a set of plausible solutions for the layout of the house. It is our hope that some of them might inspire the architect. Preliminary results of the project were reported in the papers [3], [5], and [7] to [9].

Composite Representation
    Composite Representation [9] of the design knowledge, still under development in co-operation with Dr. E. Grabska from the Institute of Computer Science, Jagiellonian University, Cracow (www.ii.uj.edu.pl), is aimed at encouraging innovative thinking of the designer. It separates clearly the description of the internal structure of the designed artefact from the description of its geometrical features. The former is coded by a graph whereas the latter is represented by a realisation scheme - a special knowledge representation format including geometric primitives, their transformations, predicates related to design constraints, etc. This methodology proved to be applicable both in civil and mechanical engineering [8][7][3].
