... The concept of search process in simulated annealing was borrowed from physical processes. More details of this approach can be referenced to the Shea's (1997Shea's ( , 2001Shea's ( , 2002Shea's ( , 2004 research works. Particular examples like traditional geodesic patterns have been constructed using shape grammars. ...

The integration of 3D shape grammars with conceptual design knowledge in a generative design system helps the development of an advanced system for the exploration of design alternatives. The key to this is the formulation of two kinds of parameterised 3D shape grammars, with which, designers' knowledge about how to create a unique form is encoded as the strategic design knowledge, represented as a set of 3D shape grammar rules. Other lower level rules are created for changing the parameters of this strategic design knowledge in an evolving and controlled manner, in order to explore and focus on the desirable outcomes. In this paper, the relevant literatures as well as the authors' past research are reviewed. It presents the framework of this generative product design system. A real product design example is used to demonstrate how this system works. It also discusses the issues for further research in this area.
... Knight (1994) gives a comprehensive overview of the theoretical foundations of shape grammars, although computer programs are not discussed. Shea (1997Shea ( , 2001Shea ( , 2002Shea ( , 2004 has developed a generative structural design system -called eiForm -that uses shape grammar techniques to generate two-dimensional and three-dimensional space-frame structures. Structures consist of planar topology of structural members. ...

Taking its inspiration from biology, digital morphogenesis operates through a logic of optimisation. Departing from the notion of architecture primarily as form-finding that privileges appearance, Neil Leach describes how morphogenesis places emphasis on ‘material performance’ and ‘processes over representation’.

The two critical issues related to product design exploration are addressed: the balance between stylistic consistency and innovation, and the control of design process under a great diversity of requirements. To address these two issues, the view of understanding product design exploration is first sought. In this view, the exploration of designs is not only categorized as a problem-solving activity but also as a problem-finding activity. A computational framework is developed based on this view, and it encompasses the belief that these two activities go hand in hand to accomplish the design tasks in an interactive design environment. The framework adopts an integration approach of two key computational techniques, shape grammars and evolutionary computing, for addressing the above two critical issues. For the issues of stylistic consistency, this paper focuses on the computational techniques in balancing the conflicts of stylistic consistency and innovation with shape grammars. For the issues of controlling design process, the practical concerns of monitoring the design process through various activities starting from the preparation works to the implementation of shape grammars have been emphasized in the development of this framework. To evaluate the effectiveness of the framework, the experiments have been set up to reflect the practical situations with which the designers have to deal. The system generates a number of models from scratch with numerical analysis that can be evaluated effectively by the designers. This reduces the designers' time and allows the designers to concentrate their efforts on performing higher level of design activities such as evaluation of designs and making design decisions.
There are building systems, called "modularized", in which the component systems (for structure, lighting, etc) can be analyzed and synthesized independently since their performance and design do not interact or affect one another. There are other building systems, called "coupled", in which the component systems do interact and influence one another. The thesis acknowledges that in a building there are both sub-systems that act independently and others that interact. While many design processes have been proposed for dealing with discrete sub-systems, there is no systematic study for building sub-systems that interrelate. This thesis examines a different design approach called integrated. The term "integrated" has a dual utilization in this study. The first use refers to the integration of form and building performance. The second use refers to the integration of interrelated and diverse building performances involving multiple disciplines. The integrated design approach analyzes and evaluates several interrelated design systems involving different disciplines in the early design phase. The goal of the approach is the generation of design alternatives guided simultaneously by two basic objectives: the aspiration for form exploration and the satisfaction of the performances of interrelated systems. After defining a framework for an integrated design approach, which includes inter-disciplinary collaboration, unified design, optimization, simulation, and other formal and digital techniques, the approach will be demonstrated in a case study. The objective of the case study is to demonstrate that the integrated design approach has validity and can be realized, in this case, for the generation of high-rise buildings guided by structural, lighting, zoning codes, and aesthetic criteria.
