TM: Transition Probability Matrix

In parniSDU/ftaproxim: Fault Tree Analysis Based on Proxel Simulation

Transition Probability Matrix

Description

This function returns a matrix of transition probabilities at a time point for a given basic event with specified transition distribution functions.

Usage

TM(G, dist, param, t, delta, states)

Arguments

G	a matrix of 1's, 0's and NA's. 1 and NA: transition is possible, 0: transition is not possible
dist	a string vector of transition distribution functions
param	a list of parameters of the transition distribution functions
t	a numeric value as time
delta	a numeric value as time step
states	a string vector of states' labels for the basic event

Value

A numeric matrix of transition probabilities.

Examples

## failure distribution function Uniform(2, 2.5)
## and a fixed repair time of 0.3
t <- 0.1
delta <- 0.2
states <- c("OK", "F")
G <- rbind(c(NA, 1), c(1, NA))
dist <- c("unif", "unif")
param <- list(c(2, 2.5), c(0.3 - delta, 0.3 + delta))
TM(G, dist, param, t, delta, states)

## failure distribution function exp(0.001)
## and not repairable
t <- 0.1
delta <- 0.2
states <- c("OK", "F")
G <- rbind(c(NA, 1), c(0, 1))
dist <- c("exp")
param <- list(c(0.001))
TM(G, dist, param, t, delta, states)
