Model-Based Design Tools for Extending COTS Components to Extreme Environments

Abstract

Model-based design (MBD) tools to predict the performance and useful life of commercial-off-the-shelf (COTS) components and COTS-based systems outside of their rated temperature range are described. The modeling tools will differ from all known technologies in that they facilitate the capture of experimental data on COTS devices that in turn is automatically transformed through novel modeling methods into newly created behavioral models with performance degradation and lifetime effects. These tools are relevant and important in providing the means to quantify the reliability and lifetime (i.e., capability and risk) of COTS components and COTS-based systems and provide a trade structure for the assessment of competing technologies. Furthermore, these novel modeling and design tools will provide a means of integrating disparate models, allow agile evolution of models, and encourage MBD reporting mechanisms be used in reviews. Ultimately, these MBD tools will enable lower-cost system development and cost versus lifetime assessment, shorten development time, and extend proven technology to broader applications.
