• Resumen

  • The computational design synthesis approach considered in this paper, proposes directed multigraph and graph grammar-based models of technical processes and technical process synthesis. The theory of technical systems, which is adopted as a theoretical foundation for this work, assumes a teleological viewpoint bringing together the purpose of technical systems and fulfilment of customer demands and societal needs. These demands and needs are met by means of a technical process inside which the operands are transformed with the assistance of a technical system to achieve a desired state. Formal models of technical processes and technical process synthesis establish the foundation for further application of search algorithms to support early engineering design. The engineering knowledge about technical processes is provided within a set of graph grammar rules. As the result of the proposed approach, the designer is enabled to consider different operand transformations in an expedient fashion with the possibility of the generation of novel alternatives. The proposed approach is illustrated through an example of the design of a stiffened panel assembly line involving welding and riveting as two basic principles.
