A Framework for Supporting Generative Product Design Using Genetic Algorithms

Jian Sun (2002)

This thesis investigates the application of generative and evolutionary techniques in computer-aided product design, aiming to create a computer model of a generative evolutionary product design process for conceptual design. This research focuses on developing a computer model of a generative and evolutionary design. A prototype system is implemented to support designers at the conceptual design stage. The study addresses several significant issues through the implementation of a generative and evolutionary system in product design, which includes: (1) the identification of two cyclically linked stages in the design process as formative construction and design development, (2) the implementation of a prototype which tests the effectiveness of the data structures and the genetic algorithms, and (3) the computational methods and representations of applying genetic algorithms to product design. The result shows the capability to generate a wide range of solutions based on initial design requirements specified by designers, and with the support of genetic algorithms and the knowledge formulated as the concepts of the rudiments and formatives.
