A scheme for emergency material allocation based on decision makers' subjective preference

Abstract Emergency Material Allocation (EMA) plays a critical role in emergency response efforts. To ensure the equitable allocation of limited emergency rescue materials to Emergency Demand Points (EDPs) under conditions of limited information, this paper proposes a novel EMA approach. The proposed method accounts for Situation Factors (SFs), which capture the severity of damage at EDPs, as well as the perspectives of Emergency Decision-Makers regarding the conditions at these points. Numerical simulations demonstrate that: (i) the approach produces allocations proportional to the severity of the disaster as indicated by the SFs; and (ii) it respects the collective opinions of EDMs, ensuring an allocation aligned with their aggregated evaluations.
