Reliability Workbench FaultTree+
Fault Tree Analysis – Why you do it and what you get from it.
Minimal Cut Sets: Combinations of component failures that cause system failure.
Failure Models: How to put numbers into a Fault Tree, so you can get numbers out.
System Quantification: A brief overview of the calculations used to quantify a Fault Tree.
For many years we have received countless request for a self paced e learning option for the FaultTree+ course. Please note that although this course has not been completed it is nearing completion.
I am looking for any feedback or questions you might have.

I’m not going to lie I head up sales for Isograph in North America. I often get labelled with some of the tactics sales people use in my industry. The best advice I can give to a prospective client is to try models using your own data and information to see how they turn out. Also, check the calculations and software options to ensure the software product will do what you want it to do not only today but next year when your model has matured. Although I am a sales person and my lips are moving I’m not lying here.
Batch append is one of those points that one should consider in a mature software product. How are you going to combine the work of many individual engineers into a final model you can use for certification or to present to management? If your tool cannot do this run for the hills!
Sometimes, when working on a large system model, you need to share the load, and split up the fault tree development to different people. But then the time comes to combine everyone’s work together. How do we do that? And how do we make sure that our master fault tree contains the most up-to-date information from each engineer’s fault trees?
This excerpt from our in-development online training course gives a quick insight into using the Batch Append feature to automate the linking of fault trees from different user’s projects, and how to keep the linked file up-to-date with the latest changes.
Of course CAPEX will effect OPEX, or it should…or will it? The idea makes sense, however, at what point will a piece of equipment cost you more to maintain than it would cost to simply replace that piece of equipment? Should a refurbish be considered? How should a new plant be configured for the highest cost benefit? Not properly designing a system or not being willing to spend the money to replace equipment at the right interval could be costing you. By modelling your system in easy to use tools you can make logical decisions as well as justifying these decisions.
The next version of Reliability Workbench (13.0.2) has now been released. Join us for this special preview webinar to get an early look at the new features that have been added. From changes to the report viewer interface, updated Prediction stands, data linking to the Allocation module, new DLL functions, expanded IEC 61508 calculations for both the Fault Tree and FMECA modules, a new Fault Tree failure model, and a brand-new results dialog for the FMECA module, complete with ISO 26262 functionality, there’s plenty to get excited about.
As always if you have any questions about our software please feel free to contact me.

ISO 26262 Compliant Safety Analyses
Isograph is pleased to announce that Reliability Workbench FaultTree+ and FMECA modules have been tested by SGS-TÜV according to ISO 26262-8:2011 and certified as suitable for safety analyses up to ASIL D.
ISO 26262 (Road vehicles – Functional safety) is an adaptation of IEC 61508 for the automotive industry. It addresses possible hazards due to malfunctions in electronic/electrical safety related systems in passenger vehicles up to 3500kg.
Isograph’s world leading reliability software is used widely in the Automotive industry for ISO 26262 compliant safety analyses.
We appreciate your support of Isograph Software, if you have any questions or recommendations for the blog posts please let me know.

Included is our most popular webinar to date, where we will took the included schematic, of a propulsion system, and demonstrated the logic used to represent this schematic in a Fault Tree. Although there is more than one way to skin a cat, our Fault Tree expert created what he sees as the most logical model to represent this system.
For the ambitious I would suggest that you build your own model in FaultTree+ prior to viewing the meeting and see how your model matches up with ours. For those using demonstration versions of the software you can build the model and save the image using “Print Screen”.
**HINT** in this example, the Fault Tree will look much simpler than the schematic. Watch for common cause failures.
Please let me know if you have any questions about this Webinar, it will be well worth your time. As always this is not a sales focused web meeting it will be an educational webinar focused on the technical aspects of building a Fault Tree.

Secret might be the wrong word to use here, it could be a matter of just asking myself or technical support the right questions. Even if you’ve been using Reliability Workbench, Availability Workbench, AttackTree+, or Network Availability Prediction for years, you’re probably still finding new features and tips and tricks to help you out in the software. Maybe one day you discovered a time-saver and thought to your self “what else can this software do to make my day easier?”
While there are plenty of helpful features in Isograph’s software to make your day easier, perhaps none is so powerful, incredibly useful, and so under-utilized as Plugins and the DLL. These features allow you to extend the power of Reliability Workbench, Availability Workbench, Attack Tree, and NAP tools to absurd heights. From creating macros for accomplishing tedious tasks, to automating fault tree construction, and even adding new features to the software that we haven’t even thought about, the Plugins and DLL can do it.
