Ensuring system safety is more efficient Available to Purchase

With continuously shrinking time to market and ever increasing requirements regarding product quality and safety, efficiency is crucial in system development. In contrast to classical simulation tools, the model‐based simulation and diagnosis tool RODON supports a wide range of analyses based on a single product model. Besides the resultant considerable reduction of modeling effort, it helps to increase safety and efficiency by automating tasks which traditionally involve a substantial amount of manual labour, like failure modes and effects analysis (FMEA). Considering a model of a typical fly‐by‐wire system as example, this paper describes a few ways how the system engineer can benefit from RODON to enhance system safety and quality, from FMEA to model‐based diagnosis. The main focus of the study was the investigation of sensor tolerances and their impact both on the system behavior and on the fault detection by the system's monitoring functions.
