The process of designing simulates the evolutionary process at the genotype level. Structures of designed objects are represented by means of graphs as genotypes. This representation of genotypes forces new interesting extensions of genetic operators. The modified crossover operator is the major computational engine of genetic algorithms. Possibilities of application of evolutionary methods and graph transformations in industrial design are presented. Our approach is illustrated by examples from the case study of chair design with the use of an evolutionary graph-based design-system.

A new approach to structural design representations in the framework of graph transformations is discussed. The representations are generated and modified by graph operations. Graphs represent structures of designs. A new software tool which enables designers to transform the design specification into the graph design structure is proposed. Examples of designing gardens and floor layouts for one-storey houses illustrate the presented methodology.
