ABSTRACT
The contemporary engineering design curriculum embraces the concept of "concurrent engineering," in contrast to a more traditional, linear "over-the-wall" design process. In the old model, only after a design was all but complete would the manufacturing engineers become involved, typically requesting numerous design changes before compromising on a modified design that was both feasible and economical to manufacture. Not only does delayed manufacturability feedback increase time-to-market, it also increases cost. The flexibility to make design changes, particularly for interdependent components of a complex system, rapidly diminishes later in the design cycle. Since over 70% of manufacturing cost typically becomes fixed in the design stage, it is vital that designers be able to accurately assess the effect of design decisions on manufacturing costs early in the design process.

Design for additive manufacturing: cellular structures in early-stage aerospace design
The immense design freedom offered by additive manufacturing yields tremendous benefits, but it also raises the question of how to best go about designing components to exploit this design freedom. In early design phases, design tools need to utilize ...
Design opportunities with rapid manufacturing
The advent of rapid manufacturing (RM) will have profound implications on all aspects of product development and manufacture. Within the design discipline, three areas are of importance, namely, design freedom, material properties and changes to the ...
Modeling economics of LSI design and manufacturing for test design selection
ICCD '12: Proceedings of the 2012 IEEE 30th International Conference on Computer Design (ICCD 2012)Many test designs (or DFTs: designs-for-testability) have been proposed to overcome various issues around LSI testing. In this paper, we propose a cost and benefit model for comparing several test designs in terms of the final profit of logic LSI design ...
