One reason for using simulation rather than an analytical model in an inventory
problem is that the simulation is able to handle probabilistic demand and lead times.
Preventive maintenance implies that we can determine when a system needs service or
will need repair.
If a decision maker knows for sure which state of nature will occur, he/she is making a
decision under certainty.
