Utilization of Electronics Cost Estimating in Conceptual Design

Abstract The trend to build more sophisticated devices with fewer financial resources continues. More complex electronic configurations are required to drive these devices, and the costs of these electronics devices have taken on a greater significance. Parametric cost analyses of electronics in the conceptual design phase are often requested to assist in economical decisions concerning device construction. This paper discusses a simple approach for comparing electronics costs during initial design activities. Emphasis is placed on the cost analyst's understanding of the technologies in question, communication with the design engineers and scientists, and analysis of design and cost uncertainty. The method includes use of a commercial cost model and is outlined in a recent electronic trade study completed for an earth observing instrument design concept at NASA Langley Research Center.
