Strategy to prioritize pipes with the highest risk. Pipes are only replaced if the budget remains positive.
1 | replace.n.highest.risk(state, n, prob.failure, max.costs = Inf)

state |
a state list |
n |
number of highest risk pipes to replace |
prob.failure |
failure rate function. Typically the same as passed to |
max.costs |
maximal amount of money allowed to be spent on this strategy |
The risk is defined as the product of the failure probability in the next year and the expected failure costs.

## into a prioritized sequence:
