Multi-regional collaborative mechanisms in emergency resource reserve and pre-dispatch design

This paper studies collaborative mechanisms in multi-regional emergency resource reserve and pre-dispatch design in the context of emerging pandemics. First, by depicting the features of the epidemic spreading in transportation networks, this work organically embeds the pandemic spreading in the migration process of residents. A multi-regional migration-pandemic diffusion model is established to predict the dynamic demand for drugs and disinfectants. Secondly, we design a three-level collaborative mechanism in emergency resource reserve design for multiple regions, including total-cost collaborative mechanism, investment-and-conversion collaborative mechanism and cross-region-dispatch collaborative mechanism. Finally, the effects of multi-regional demand forecast and the collaborative mechanisms on emergency resource reserve and pre-dispatch design are numerically analyzed. The findings show that ignoring the interregional migration of infected people leads to a serious shortage of emergency resources. The total-cost collaborative mechanism has little effect on the amount of emergency resources shortages in each region. The investment-and-conversion collaborative mechanism may exacerbate the shortages of certain types of emergency resources. The cross-region-dispatch collaborative mechanism can evenly prevent the shortages of emergency resources between the cooperation regions.
