   * `-csv <file>` per salvare i risultati delle run in un file csv
   * `-p` per fare le simulazioni in parallelo (ovvero su più thread)
   * `-end <criteria>` per scegliere quando la simulazione finisce nel caso non ci siano dei source limitati nella creazione di arrivi. La tipologia di fine simulazione la si può trovare dentro `EndCriteria` (ovvero MaxArrivals, MaxDepartures, MaxTime) e la formattazione da usare per passare il parametro è la seguente:\
-  `[Tipo1:param1,..,paramN];[..];[TipoN:param1,..,paramN]`
