Examples

## define a strategy function that can be passed to simulate_network():
mystrategy <- . %>% replace.n.oldest(n=10)

## or define a more complex strategy by combining multiple strategies
## into a prioritized sequence:
mystrategy <- . %>%
  replace.more.failures.than(failures=2) %>%
  replace.n.oldest(n=3) %>%
  replace.n.highest.risk(n=2, prob.failure=prob.failure.exp) %>%
  replace.older.than(age=8) %>%
  replace.n.random(n=4)
