FAA Research Project on System Complexity Effects on Aircraft Safety: Testing the Identified Metrics

Abstract

The purpose of this report is to describe a test of the complexity algorithm that we developed and previously described in the report for Task 3.5: Estimating Complexity of a Safety Argument [Konrad 2016]. The algorithm did not measure every possible kind of complexity; rather it measured the complexity resulting from errors propagating from component to component; thus we call it error propagation complexity. The example used in this test was a Wheel Brake System that had an available model in the Architecture Analysis and Design Language (AADL), a much more involved example than the stepper used in the previous report. Its error propagation complexity turned out to be about twice that of the Stepper Motor System.
