Jeremy Hynek

Isograph is pleased to announce that we have been accepted as a SMRP Approved Provider. If you are not familiar with SMRP (Society of Maintenance and Reliability Professionals), but are interested in maintenance, reliability, availability as well as learning various industry techniques for figuring how to approach your maintenance and reliability. Its worth you time to take a look at this nonprofit professional society. .

Going forward, if you attend either our Availability Workbench RCMCost or Availability Workbench Avsim courses you will receive 8 hours per course towards your CMRP continued education.

For additional information on our training courses: TRAINING

For more information on the CMRP certification: CMRP

The Approved Provider Education Program recognizes continuing education that aligns with the most relevant topics and best practices in the industry according to the SMRP Body of Knowledge and/or the Asset Management Landscape, which is published by the Global Forum on Maintenance and Asset Management (GFMAM).

The program serves as a resource for professionals looking for training and continuing education that is verified by a qualified third party. For Approved Providers, the program offers validation and recognition of their training and educational courses….” (

How to use Weibull to analyze historical data

Jeremy Hynek

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
• Weibayes
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 . 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.

Upcoming training……

Jeremy Hynek

As many of you know we don’t exactly get our of the office every week to offer public training courses. Please don’t miss your opportunity to attended one of Isograph’s training sessions to be held in Park City, Utah the week of June 27th, 2016. We will be offering training on Isograph’s Reliability Workbench, FaultTree+ and Availability Workbench Software. In addition to the training in Park City will also be offering training in Houston this September, which will include our IEC 61508 training. For a complete list of dates please check our website: .

The upcoming training in Park City offers an ideal location. Just 40 minutes from SLC international airport, Park City was home to the 2002 Winter Olympics and offers many lodging options and is well know for it outdoor/night-life activities. .

New this year we will begin to offer self paced web training. For more information please contact myself or Joe Belland: .
On a different note, for those Reliability Workbench users don’t miss our “What’s New” webinar this Wednesday at 12pm EST. In this Webinar we will go over the upgrades added to Reliability Workbench Version 13.

Fault Tree model from a schematic recap

Jeremy Hynek

Thank you to everyone that attended our last meeting “building a Fault Tree from a schematic”. I realize that there were many that were not able to attend the meeting. The warning that there are limited seats held true and the meeting did fill up leaving many of you to wonder what the proper logic was to modeling the schematic posted.

Not to worry, the meeting was recorded and can be accessed from the following link:

Since everyone in the meeting was muted watching the recording is almost as good as being there.

However, don’t miss the chance to watch this weeks meeting live where we will be showing how to create various reports on the model we built last week. The same goes this week… please sign up to save a place in the meeting.

As always please contact me with any questions.

Best Regards, Jeremy

Is your modeling logic…logical?

Jeremy Hynek

When modeling (or modelling for those of you in the UK) your system in a Fault Tree or Reliability Block Diagram do you ever wonder if your logic is covering all possible failures or properly accounting for redundancy in your system?

Try your hand at modelling the included schematic in a Fault Tree or Reliability Block Diagram (RBD) then join us on a Webniar, Friday at 10am PST, to see if your model matches up with the model one of our support experts comes up with. If you do not have access Fault Tree Analysis or RBD software please let me know and I will lend you software to use during this meeting.


The safety system is designed to operate as follows: should a runaway reaction begin, the temperature sensor (TS1) and pressure sensor (PS1) will detect the increase in temperature and pressure and start the safe shutdown process. The provision of two sensors is for redundancy; only a single sensor needs to register the unsafe reactor conditions to engage the safety system. Should either TS1 or PS1 detect a runaway reaction, two things will occur: 1) a signal will be sent to the controller (CON), which will close the electric valves in each reactor input (EV1 and EV2), and 2) the alarm (ALARM) will sound, signaling the operator (OP) to close the manual valve in each reactor input (MV1 and MV2). In order to stop the runaway reaction, BOTH inputs must be shut down. However, only one valve on each input needs to be shut. So only MV1 or EV1 must be shut to stop input 1, but at least one valve on input 1 and at least one valve on input 2 must close to stop the inputs to the runaway reaction. Note that EV1 and EV2 (and only these components) are powered by the electrical grid; all other components have independent battery backups or power supplies.

FaultTree+ (IEC 61508) Training April 29th and 30th, 2014 Deerpark Texas

Jeremy Hynek

We are happy to announce that Dow Chemical will be hosting Isograph’s FaultTree+ IEC 61508 training again this year in Deerpark Texas near Houston on April 29th and 30th, 2014. Last year’s class sold out quickly so be sure to save a spot in this class. Depending on your industry there are several adaptations of the IEC 61508 which include: the ISO 26262 for automotive, the IEC 61511 for SIS in process safety, the IEC 61513 for Nuclear power, IEC 62279 for Rail Software as well as many others. Basically if you are calculating System Integrity Levels (SIL) or Safety Instrumented Systems (SIS) we have you covered.

This two-day course will give users a brief overview of fault tree methodology, then focus on the many features in Reliability Workbench 11.1 designed to assist with safety instrumented system/safety instrumented function analysis according to IEC standard 61508.

For more information on our course schedule and course descriptions please refer to our website: Isograph FaultTree+ training .
