This paper describes the transformation of an existing set of heterogeneous product knowledge into a coherent design repository that supports product design knowledge archival and web-based search, display, and design model and tool generation. Guided by design theory, existing product information was analyzed and compared against desired outputs to ascertain what information management structure was needed to produce design resources pertinent to the design process. Several test products were catalogued to determine what information was essential without being redundant in representation. This set allowed for the creation of a novel single point of entry application for product information and the development of a relational database for design knowledge archival. Web services were then implemented to support design knowledge retrieval through search, browse, and real-time design tool generation. Further explored in this paper are the fundamental enabling technologies of the design repository system. Additionally, repository-generated design tools are scrutinized alongside human-generated design tools for validation. Through this process researchers have been able to improve the way in which artifact data are gathered, archived, distributed and used.
Information technology has played an increasingly important role in engineering product development. Its influence over the past decade has been accelerating and its impact in the coming decade will undoubtedly be immense. This paper surveys several research areas relating to knowledge representation, capture and retrieval, which will have a growing influence on product development. Each of these areas could, on its own, provide sufficient material for an entire survey paper. Unlike traditional survey papers, this paper does not attempt to provide a comprehensive review of a field of research from its inception to the present. Rather, this paper aims to touch on a representative selection of recent developments in these influential technical areas. The paper provides perspectives into the kinds of technologies that are emerging from rapidly expanding fields of research, and discusses challenges that must be overcome to enable transition of these technologies into industry practice to support the next generation of product development software tools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
