“…The first stage is considered as the crucial stage within a bridge design process. Wood and Agogino (1996) cited various sources that demonstrate the conceptual design stage, which takes up the initial 10-20% of the total design time, influences the entire design process including costs. Moreover, Xu, Li, Li, and Tang (2005) and Machwe and Parmee (2007) stated poorly conceived design concept can never be compensated by a good detailed design and also the importance of taking correct decisions early on in the design process is now well understood.…”

“…This is so because during the conceptual design stage, design activity is still based around human designers and requires them to draw on their experience and skills to come up with novel solutions to design [4] problems. Furthermore no machine based design function can replace the judgment of an experienced and skilled designer especially when evaluating the solutions subjectively (for example visual aesthetics in case of an automobile).…”

This paper reviews the development of an interactive evolutionary design system (IEDS) for conceptual design, which integrates an agent based 'build and evolve' approach with a component based representation. It builds upon the previous work done by the authors involving interactive design of bench-like structures and describes the extension of the system to handle the design of free-form urban furniture. The extensions include integration of solution clustering and a free-form design rule-base, within the IEDS. The presented results highlight the various advantages of combining an agent based solution assembly method with a component based representation.

This article describes research relating to a user-centered evolutionary design system that evaluates both engineering and aesthetic aspects of design solutions during early-stage conceptual design. The experimental system comprises several components relating to user interaction, problem representation, evolutionary search and exploration and online learning. The main focus of the article is the evolutionary aspect of the system when using a single quantitative objective function plus subjective judgment of the user. Additionally, the manner in which the user-interaction aspect affects system output is assessed by comparing Pareto frontiers generated with and without user interaction via a multi-objective evolutionary algorithm (MOEA). A solution clustering component is also introduced and it is shown how this can improve the level of support to the designer when dealing with a complex design problem involving multiple objectives. Supporting results are from the application of the system to the design of urban furniture which, in this case, largely relates to seating design.
