Setting the confidence error function

I would like to set error function for failure probability (which is not depend on time) in Function_Element or Action_Element.

Is it possible to do so?

  I don't completely understand your question.  We provide many failure distributions. Can you be more specific regarding what you want to do?

  Rick,

  I'd like to define the accuracy of failure rate by components.

  When there are two components which failure rate is constant regardless of time as attached diagram, I'd like to define error bars depending on the failure rates.

  For example, component A's failure rate=0.1±XX (Error factor=3)  and component B's failure rate=0.2±YY (Error factor=5) 

  Does what I said make sense? and is there such a function in GoldSim's reliability module?

  When you define a failure mode, the failure is stochastic.  For example, for an Exponential failure rate, the failures are sampled from a Poisson distribution:

  You need to specify a Rate of Failure.  This itself can be uncertain (a probability distribution).
