Description/Abstract
This paper presents a novel technique for representing cost information of a candidate design. The underlying
principle is to provide a knowledge-based system for cost modelling that makes the cost effects of
design decisions more visible and quickly available to the designer. The development of a hybrid between
hierarchical trees and object-oriented knowledge representation environment to represent cost information
is shown. The development of an abstract product structure, reusable tree object libraries and an automated
system to extract design information needed for estimation from computer-assisted design geometry is
discussed. It is shown how the tool provides fast incremental cost fluctuations in response to changes in
component geometry. This paper also considers the uncertain quantities present in cost models and analyses
cost risk. A case study demonstrating the research applied to a Rolls-Royce aircraft gas turbine engine
component is presented
