Fault Injection Software Tools and Robust Design Principles for Reliability and Safety in Measurement Science Education

Abstract

In the design of measurement systems we face the fact that parameters are subject to (measurement-) uncertainties. Additionally, components may behave entirely different from what is specified, which is then considered a fault. Consequently, both uncertainty as well as probability of failure should be considered in education on robust design and reliability. In this paper we present a teaching concept based on hardware fault injection using a simple level sensor system as an example. Learning objectives are faults, errors, failures, false alarms versus misses as well as advantages and disadvantages of redundancy.
