Instantaneous Unavailability Vector
Description
This function calculates the isntantaneous unavailablity/reliabality values of a basic event.
Usage
ProxelBE(BE, state, totaltime, delta, tol)
Arguments
BE |
a list containing states, transition matrix, distributions and their parameters for a basic event |
state |
a string value for the state |
totaltime |
an integer value for the total time |
delta |
a numeric value as time step |
tol |
a numeric value for the tolerance level |
Details
For a multistate event, if the state is IS this function returns a vector of instantaneous probabilities of being in the intermediate state
Value
a numeric vector of instantaneous unavailabilities when the state is F
Examples
#A multi-state basic event with Weibull(2, 3) transition distribution function
#from working (OK) to an Intermediate State (IS), a fixed time of 0.5 transtion
#from IS to failure (F), and a fixed repair time of 0.1 (transition from state F to state OK).
