“…At this stage, SCs are experiencing initial misbalances in supply and demand due to longer lead-times, demand drops, and supply unavailability due to facility closures. OR methods can support SC managers at this stage by stress-testing the existing and alternative SC configurations and production-distribution plans for some scenarios of structural dynamics in anticipation of, or as a reaction to, facility and market closure due to quarantines and lockdowns ( Hosseini & Ivanov, 2019 ; Tan et al, 2019 ; Li and Zobel, 2020 ; Sawik, 2020 ). OR methods can also help optimize contingency-preparedness plans for their efficient and timely deployment under different scenarios of epidemic propagation ( Liberatore et al, 2012 , Ghadge et al, 2013 , Ivanov et al, 2015 ; Sinha et al, 2020 ; Pavlov et al, 2019 ; Goldbeck et al, 2020).…”
