“…In this context, the introduction of uncertainty with simulation makes the situation closer to reality and with the definition of robustness it is possible to achieve a solution that might be not mathematically optimal but more resilient to disruption in the real system. DES has been widely used in many fields, from manufacturing to transportation, already since the last decades, and it has been proven to be useful for what-if analysis, scenario testing, and as a decision support tool (Banks 1998, Brunner, Cross, McGhee, Levis, and Whitney 1998, Negahban and Smith 2014. In DES, time passes according to the occurrence of specific events and the sequence of actions that the entities make are already known in advance.…”
