Production Buffer impact over MTBF, Availability and System Reliability within the RBD

  • 1.  Production Buffer impact over MTBF, Availability and System Reliability within the RBD

    Posted 07-31-2022 09:33 PM
    Hello everyone,

    Hopefully all are doing well. Has anyone done the calculation/analysis of the impact from a production buffer between two assets within a RBD? I am trying to calculate the increase on Availability and expressing  MTBF as a function of the Availability; since having the stockpile (buffer)mitigates the risk of not having the available raw material for the process downstream. In summary, we increase the reliability of that system. My question is, if this buffer would behave as a "redundant asset" virtually? I am assuming this because while the first asset is down (asset before the buffer), then the buffer will replace the lack of material; until the first asset will run again (ideally), even though the asset is in series with the buffer...

    Your feedback would be appreciated .

    Best Regards

    Rene M. Davila

    Rene,
    Fun thought. However, buffer is an issue to the production process.  The issue of interest would be maintainability which is the elapsed time from going down to return to service. The buffer amount would be set according to what you want to assure for the production process to continue until all is once again well.
