Parametric Eco-Efficiency Analysis: A DfE Support Tool

In this paper a methodology is described that allows providing pro-active DfE support based on functional requirements available in ea rly design stages. The method, called Eco-PaS, is based on an expert system that contains basic knowledge of a range of design alternatives for different sub-systems. These are made available to the designer as functional blocks. Based on the functional requirements s pecified b y the de signer, appropriate technical specifications are determined. These allow an instant comparison between different design a lternatives for each functional block. The p roposed method has been implemented and tested for a range o f elementary functions in the field o f machine de sign, showing promising results. A number of examples illustrate the developed methodology.
