Rather than run trial replications in order to estimate how many replications are necessary to ensure the accuracy of a particular output, we can use dynamic simulation
. Dynamic simulation measures the accuracy, i.e., half-width, of an output at the end of each replication and stops replicating once the desired accuracy has been achieved.
In Arena, this is implemented by setting the maximum number of replications "on the fly". However, this means that one extra replication is always performed.
More to come!
