“…14 In fact, it would seem as if the 'polynomial nomenclature' format of architectural identification and classification systems has been adopted from engineering practices. At any rate, one will find schemes of the exactly identical format at work in manufacturing design and in engineering in general, where these practices began to develop after the Second World War (Mitrofanov, 1959;Opitz et al, 1969;Opitz, 1970).…”

In their cooperative effort, architects depend critically on elaborate coordinative practices and artifacts. The article presents, on the basis of an in-depth study of architectural work, an analysis of these practices and artifacts and shows that they are multilaterally interrelated and form complexes of interrelated practices and artifacts which we have dubbed 'ordering systems'. In doing so, the article outlines an approach to investigating and conceiving of such practices.

“…Then components are classified and clustered with respect to the code similarity or distance using one of the clustering algorithms. This concept was first introduced by Mitrofanov (1959) and Opitz et al (1969). Although it appears that most of the early applications of group technology (GT) have employed the C&C techniques, however, there are a number of reasons that make C&C approaches an unsatisfactory method for finding GT groups and families (Burbidge 1989).…”

Cell formation is a procedure that involves identification of product families and their associated machine cells. This paper proposes a new cell formation algorithm, called heuristics rules-based logic (HERBAL), which belongs to the class of array-based matrix formulation algorithms. The algorithm incorporates the machine-component incidence (MCI) matrix to identify the component or part families and their associated machine groups. The algorithm, to an extent, overcomes some of the known drawbacks, such as in manipulating ill-structure machine-part matrices, attaining rational sizes of cells and employing weighted machine-part matrices. The proposed cell formation algorithm has been tested on a number of well-known data sets obtained from the literature as well as on a number of randomly generated data sets. In both cases, it has demonstrated successful groupings, in terms of the grouping efficiency, grouping efficacy and quality index measures.

“…There are several coding systems developed to identify the design and manufacturing attributes of mechanical components (Groover and Zimmers 1984;Rembold, Nnaji, and Storr 1993), such as the best known Opitz coding system which is used to develop part families (Opitz 1969). Here, a name coding protocol is proposed to name the stored design cases.…”

The advancements in internet technology have had a tremendous impact on the development of knowledge-based engineering systems that support concurrent engineering. Not only the conventional knowledge acquisition and representation techniques need to be improved to adapt the new situation, but the information retrieval and distribution have arisen to be new questions to answer. This article addresses these issues of management and handling of knowledge in a knowledge-based intelligent design system. A search algorithm based on the computation of a similarity index is proposed to retrieve a design case from the project library. An initial design report is used to distribute design information so that the information such as a designer's intent which cannot be included in a standard CAD file, can be retained. In addition, a simple constraint definition frame is presented to define the relationships between critical design parameters, and two information representation schemas, information matrix and constraint tree, are described. The presented research efforts in this article aim to provide promising tools to harness the full potential of ontologies in knowledge management within an intelligent design system.
