Estimating complex system robustness from dual system architectures


Abstract

This paper investigates differences in robustness and reliability between hardware only and hardware-software products presented in the patent literature. Simplified models explore the reliability and robustness between these products.

In general the more complex hardware-software systems provided higher robustness but below average reliability. Complexity is a good indication of the decreased reliability and increased robustness.

Systems that require both high complexity and reliability require large investment, extensive testing and attention to system level failures. Some examples of this phenomena are presented from industry.
