Default Downing events RS DECI and RS FCI

What is a 'downing event'? I've trawled through the Reliasoft help pages, (and have probably missed the definition, somewhere).

I'm trying to get my around the difference between RS FCI and RS DECI. I can only think that a downing event isn't a failure but an 'outage'.......

The panic is off. I found it in the Reliasoft's web pages. How I missed it, I have no idea

Hiii!

Sorry, I wrote my question in Spanish. I can't see the difference between RS FCI and RS DECI. I would be grateful if someone could explain it to me

Hi Marta,

RSDECI is defined at http://reliawiki.org/index.php/Repai...lation#RS_DECI.

RSFCI is defined at http://reliawiki.org/index.php/Repai...ulation#RS_FCI

I hope this helps.

Question Re: Downing events RS DECI and RS FCI

Thank you David but I have already read that information.
RS DECI: This is a relative index showing the percentage of times that a downing event of the block caused the system to go down.

RS FCI: This is a relative index showing the percentage of times that a failure of this component caused a system failure.



I can't see the difference between these two definitions. I think that the use of failure and downing event is confusing me

Hi Marta,

A failure is a downing event, however a component may have other downing events which may bring the system down. Examples might include:
  • Inspection
  • Preventive maintenance
  • Corrective maintenance
A list of downing events is available at http://reliawiki.org/index.php/Repai...Downing_Events.

I hope this helps.

Exclamation Re: Downing events RS DECI and RS FCI

Hiii!

I have more questions related to Reliasoft. Maybe you can help me.

- On the table "System overview" there is a field called "Expected number of failures" and the result doesn't match up with the sum of the different subsystems of the field "Expected number of failures" of the table "Individual Block Summary". Do you know why this happen?

- The availability of my system and that of my colleague is very very low (lower the more time goes by) but the availability is very high. Why is there so much difference between these two parameters?

Thank you very much for everything!!!
