For each scenario we have run multiple independent replications and combined together the results to produce the final output using a Monte Carlo method [21], which basically assumes that every replication is a snapshot of the system at a given time and all snapshots are equally representative.
The samples collected in the initial phase of each replication (warm-up period) have been withdrawn from the results.
The duration of the simulation and warmup period, as well as the number of replications per scenario,have been set based on a detailed calibration study, whose results are not included.
