Although some might have superstitious feelings about Friday the 13th. We have chosen to hold a webinar to get you away from all the coffee talk. For Friday the 13th we have come up with a special preview of our next version of Reliability Workbench which is also version 13 (specifically 13.0.2). Join us for this special webinar, on Friday October 13th at 12 PM Eastern Time, to get an early look at the new features that have been added. We have added significant 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.
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.
Following feedback from users, it seems as though we can never post enough FaultTree+ web demonstrations. Included is general overview of our popular FaultTree+ software. In addition to an explanation on how the tool is used we have also added some useful information on import/export, search functions, customising the grid view, calculation options, approximation methods, Markov….ext.
As always if you have any questions on the web demonstration or need additional informaiton on our software products please feel free to contact me.
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.

We have collected commonly asked questions by our 1000’s of users. Some of the questions that we’ll answer along the way include:
Why do my cut sets show gate names with an asterisk next to them?
OK, so I enter a “failure rate.” Is that failures per… hour? Year? Geological epoch? What are the units?
This fault tree takes ages to calculate. Can I speed it up?
Fault tree uses approximation methods for solving the tree? Do I have any control over that?
My computer crashed and I lost 3 hours of work! Can I create automatic backups of my project?
What if I want to see MTTF on my fault tree, instead of Q?
I have a plotter. How do I print the whole tree on one piece of paper?
Can I force scientific notation in the results?
What if I don’t want to delete the inputs to a gate when I delete the gate?
I really love the font Comic Sans. Can I use that in my fault tree?
Also, chartreuse is my favorite color. How do I set that as default?
How do I set default options, so I don’t have to reset these every time I start a new project?
We’ll also look at the useful and often-overlooked Report Options. Did you know that you can force the diagram to be black & white for printouts? Or make the fault tree symbols bigger? Or change the order of the pages?
In our webinar series “How to Use Your Tools”. We spent about 30 to 40 minutes covering the topic of using Weibull to analyze historical information. This is an educational webinar intended to teach our users and prospective users how to better use our tools to properly model their systems.
Weibull is another treasure to add to your analysis. Weibull analyzes historical failure or repair data and assigns probability distributions which represent the failure or repair characteristics of a given failure mode.
The failure distribution assigned to a given set of times to failure (known as a Weibull set) may be assigned to basic events or generic failure models in the Fault Tree Analysis module and to reliability blocks or generic failure models in the RBD analysis.
The Weibull Analysis Module analyses times-to-failure and time-to-repair data using the following distributions:
• Exponential Distribution
• 1-Parameter Weibull Distribution
• 2-Parameter Weibull Distribution
• 3-Parameter Weibull Distribution
This webinar is the 6th webinar in this series, topics already covered:
• Fault Tree Analysis
• Fault Tree Analysis and the IEC 61508
• Data Links FMECA to Fault Tree
• Event Tree Analysis as part of a Fault Tree Study
• How to use Markov in an FTA or RBD
• How to use Weibull to analyse historical information
Past webinars can be viewed on our blog www.blog.isograph.com . Its not necessary to have attended past webinar to attend our current webinar. However, for a bit of free training it will be useful to check out the series so far.
We appreciate your support of Isograph. If you have any general questions or comments please feel free to contact me.
