Neutral Product

This paper reports some aspects of the work being carried out on the NEUTRABAS project under the ESPRIT II European research program. The aim of this project is to specify and implement a neutral product definition database for large marine-related artifacts, covering a large part of the complete product life-cycle. The results of this research program will facilitate the effective exchange of product related data between disparate computer-based information systems, and hence promote a movement towards product life-cycle integration. The scope of the product model being developed as the basis for this integration is described in terms of its spatial and steel structural components, together with the implications for integration with other models of outfitting and engineering systems. The model is shown to encompass the wide range of product-related data which is associated with the various precommissioning stages of the product life-cycle. A suitable database architecture designed to support product data exchange and full life-cycle integration based on this product model is described and discussed.

Life Cycle Stages

Features allow one to associate human knowledge and product geometry. The authors proposed, in earlier publications, a unified feature modeling scheme with the aim to maintain the integrity and consistency of a product model. Different application feature models within and across different product life-cycle stages are integrated, and especially, nongeometric relations (besides geometric ones) are handled. In this paper, as an improvement to the previous work, two types of associations are introduced: sharing and dependency. In the context of conceptual and detail design stages, these associations are described and the implementation is discussed in detail.

Industries often employ heterogeneous computer aided tools (CAD/CAE/CAM) to carry out complex product designs and simulations resulting in a need for data sharing, data exchange, and computational activities. Nowadays the concept of “Design for Sustainability (DfS)” heightens this challenge, as most DfS approaches especially the Life Cycle Assessment (LCA) involve large amounts of data collection, sharing and computation tasks throughout the product life cycle. ISO 10303, also known as STEP (STandard for the Exchange of Product model data), has evolved for several decades and provides a set of standards for industrial automation systems and integration. In this paper, we propose a STEP-based collaborative framework to integrate heterogeneous CAD tools, LCA tools and other necessary computational tools to support cooperative product design for sustainability. The geometric information from CAD tools and the material/process information from material/process databases are formally represented in suitable STEP application protocols (APs). An agent is implemented to parse the geometric and non-geometric information encoded in STEP data format, and compose them into a complete product tree represented with a NIST CPM (Core Product Model) based information model. The information in the product tree is then evaluated by a LCA tool to obtain environmental impact score. The feasibility and benefits of the proposed methodology have been illustrated with a typical stapler product.
