Introduction 37 Questions with Claudius Jordan Welcome to the fifth edition of our "37 Questions" series, where we explore the people who make Modelwise special in a fun and casual way. Why 37? It's inspired by a fascinating Veritasium video that reveals the unique...
The Swiss Cheese Model: A Simple Tool to Understand Complex Failures As we entered the second week of 2024, Munich found itself in a cold embrace, with temperatures plunging below zero. This icy chill combined with snow mirrored the conditions of early December 2023,...
FMEA: A Powerful Tool to Anticipate & Avoid Potential Failures Halloween and FMEA in a single sentence? Now, that's a truly unique pairing! Despite their initial mismatch, there is more to it than meets the eye. Through the analogy of planning a Halloween party,...
In this article, we present a template for gathering & structuring all information required by a human or software to perform a failure-mode-and-effects analysis (FMEA) using formal languages. The practical use of such a template for safety analysis is highlighted through the safety analysis (single point of failure) of a voltage monitor presented in the “ARP4761 recommended practice for aerospace system safety assessment”.
The HIMax is an industrial safety-critical system of the HIMA Paul Hildebrandt GmbH that contains multiple digital output modules, whose signals are intended for use in a programmable electronic system. In this article, a partial safety analysis of the HIMax is assessed with paitron.
This article aims to show how the tool concept of paitron was evaluated from TÜV SÜD and regarding its certification ability as a qualified software for the use in safety-critical applications.
In this article, we compare a manually generated expert failure modes and effects analysis (FMEA) taken from SAE ARP4761 with an automatically generated one, produced with paitron and find where the ARP 4761 went wrong.
