Repair, Replace or Refurbish?

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.

Availability Workbench; RCMCost, AvSim, ERP portal

Although we post a lot of web demos that cover analytical topics related to the Reliability Workbench let’s remember that the Availability Workbench is probably the most powerful tool of its kind on the market. There is a good chance someone you know is using the Availability Workbench!

Availability Workbench is used to optimise maintenance and spares policies, predict system availability and throughput and estimate life cycle costs. It includes well known modelling methods such as FMECA, Reliability Block Diagram Analysis and Fault Tree Analysis.

The following web demo is a high level overview of the software, if you have any questions or need more information on the software please let me know:

Inside conversation on the SAP portal

SAP can be a great tool for collecting data, however, that data often gets over looked or instances get looked at one by one. Often engineers  wonder what to do with all of that great data collected in SAP? Using the Availability Workbench’s certified SAP portal one can import data regarding PM intervals, spares, labour or any other fields that are applicable to the availability, maintenance or reliability of your system.

I have recorded a recent internal meeting regarding the options and benefits offered by Availability Workbench SAP portal.  As always please let me know if you have any questions or need additional information on the portal, jhynek@isograph.com

 

Reliability 2.0 Presentation

Next week we will be attending the Reliability 2.0 Conference in Las Vegas. Something interesting about Isograph is our hand-picked staff.  We have 4 PHDs to support Isograph’s Software, Training and Programming efforts. This includes Dr. David Wiseman who will be presenting his paper titled: “Availability Analysis and Design Selection using Monte Carlo Simulation”.  Below is a photo from his last presentation at IMC, what you cannot see in this photo is the people standing in the hall! So if you plan on attending this paper arrive early and bring your camping chair to ensure you get a seat.

Reliability 2.0….. cliff notes

This years Reliability 2.0 meeting in Las Vegas was a great meeting with a bit of bowling, gambling and interesting discussions on topics like Monte Carlo Simulation. (Which seems like a fitting topic for Las Vegas.)  Reliability 2.0 2014 included 2 papers authored and co-authored by Isograph employees. Dr. Gabriel Lima’s (Isograph Partner) paper titled “Practical Models for Decision-Making in Asset Management” . As an economics professor Gabriel was able to give a unique point of view regarding what motivates asset management strategies. Factors such as increased reliability, improve availability, reduced unit cost, reduced risk and improved frequency of failure .  Below is a photo from Gabriel 3 hour training course. If you are interested in the course notes please contact me jhynek@isograph.com .

Dr. David Wiseman a die hard Liverpool soccer fan, nuclear physicist  and employee of Isograph also presented a paper titled “Monte Carlo Simulation as an Aid to PM Optimization” .  In this paper David clears up the common misconception that massive amounts of data are needed to perform a simulation to optimize your PM intervals.  For a basic simulation all that is needed is the Mean Time To Repair (MTTR), the price of the PM interval and less than a weeks worth of test data. Using this data a recommended PM interval and Cost Benefit Ratio are easily calculated.

We all walked away from the conference with minor gambling losses and a better idea on how to approach our asset management models. For additional information please contact Isograph: 949 502 5919 jhynek@isograph.com , www.isograph.com

Reliability 2.0 paper “Monte Carlo Simulation as an Aid to Optimization”

This spring there will be a lot of activity in Las Vegas. Some will be calculating their losses from March Madness, others will be finishing Spring Break with a yard of ale on the strip and David Wiseman and I will preparing to present our paper “Monte Carlo Simulation as an Aid to Optimization” at this years Reliability 2.0 conference. Reliability 2.0 Agenda April 7-11, 2014

Monte Carlo simulation techniques allow computer programs to emulate plant behavior and quickly assess the effects of alternative PM policies. In this presentation we will demonstrate how to optimize PM intervals. We will also show how simulators may be used to optimize spare part storage levels – a vital consideration when restocking is subject to long lead times. Such optimization techniques can help to reduce maintenance and spare part storage costs, while taking into account safety, operational and environmental risk.
