[i10] Warning and Degradation Concept … a different view

As an automotive system developer, you might well know the meaning of a Warning and Degradation Concept. It describes the various ways, how any irregular and potentially hazardous behavior of the vehicle or a part of it is being handled, if it is not possible to reach a safe state within the so-called Fault Tolerant Read More …

[i09] The ISO26262 Concept Phase visualized – Structuring the first ideas

There is a first rough idea what the designated product shall do. Good! – Or maybe there is already a product and you just want to upgrade its functionality. Also fine! But what’s next? – How do you really get started with system development? – And how to consider safety? – Actually these very first Read More …

[i08] At the boundary to a new year …

How do you spend these days at the very end of a year? “Hidden” between Christmas and New Year this period often feels as if it is somehow “protected” from the regular business activities. Many people are on vacation – you, your business partners, clients, … (maybe even your service providers ;-(  ). It is Read More …

[i05] Collaborative Tools for System- and Safety-Engineering – Ongoing Discussions

What are real „collaborative” tools in the system engineering process of complex systems? – Throughout today’s product development process there are a lot of typical islands of data, e.g. DOORS for Requirement Management, Visio for the Architecture drawings, Simulink for the analysis, FaultTree+ for Safety-/Risk-assessment, … and MS-Office to glue it all together. Independent of Read More …

[i04] Electrical HV-Propulsion System of Light Rail Vehicles

Light rail vehicles are typical applications of electrical high-voltage propulsion systems. Since decades trams are driven by electrical motors, supplied by power fed into the vehicle from the overhead line via the pantograph. Apart from this basic architecture today’s urban transportation vehicles have less in common with the old-style tram you might have in mind. Read More …

[i03] The matrix of fault analyses

When it comes to the question of categorizing some of the standard analysis methods in the field of safety and risk engineering, one of the illustration that I use are the two “axes of knowledge”: the knowledge about the causes and the knowledge about the consequences. If for both axes we consider just the two Read More …
