 Each set of hybrid scenarios involves 1 to 6 hubs. The locations of conference hubs for each scenario are determined using the facility location optimization model for shortest total travel distances. Moreover, the facility location optimization model also makes decisions for participants on whether they attend virtually or which hub should they go.
