Standards for Collaborative Product Development

We are currently witnessing the emergence of an Internetbased engineering marketplace, where engineers, designers, and manufacturers from small and large companies are collaborating through the Internet to participate in RFQs (requests for quotes), create supply chains, and form virtual enterprises to more efficiently satisfy customer needs. The next generation manufacturing environment will consist of a network of engineering applications, where state of the art multimedia tools and techniques will enhance closer collaboration between geographically distributed applications, virtual reality tools will allow visualization and simulation in a synthetic environment, and information exchange standards will facilitate seamless interoperation of heterogeneous applications. In this paper, we discuss the role of standards in the "Internetbased web-enabled knowledge-intensive and seamlessly integrated distributed collaborative design" vision. The paper will discuss various kinds of standards for interoperability among traditional, knowledge-based, and immersive CAD (Computer-Aided Design) systems. Current standards, such as STEP (Standard for the Exchange of Product model data) developed by the International Organization for Standardization (ISO) TC 184/SC4, and future knowledge-based standards for the capture, exchange, retrieval and reuse of engineering product development data and knowledge will be discussed.
