A companion online planning tool is developed in order to view the outputs on the number of ventilators needed and the shortage that might happen under various conditions [9] . This website is available at https://covid-19.iems.northwestern.edu. The users can choose the demand scenario (Cases I-VI) and choose different options for parameter γ, the fraction of ventilators used to care for non-COVID patients, parameter τ , state's willingness to share the fraction of their initial COVID-19-use ventilators, parameter ρ, the state's risk-aversion to sending their idle ventilators to FEMA for use in a different state, and parameter L for lead-time. The results on the website are shown in interactive graphical and tabular formats. A snippet of this online planning tool is given in Figure 4 .
