Abstract

This paper presents a novel technique for representing costs of a candidate design. The underlying principle is to provide a tool that makes the cost effects of design decisions more visible and quickly available to the designer thus reducing product development time. The development of an object oriented environment to represent cost constituents of an abstract product structure, reusable object libraries and an automated system to extract design information needed for estimation from CAD geometry is discussed. The tool will provide instantaneous incremental cost fluctuations in response to change in component geometry. It also models the uncertain cost constituents and analyses cost risk. A case study demonstrating the research applied to a Rolls-Royce aircraft engine component is presented. This research has been directly funded by Rolls-Royce and the research team are grateful for being given permission to publish these results.
