Abstract

To address the multi-period demand for relief supplies among disaster-affected populations following sudden emergencies, this paper proposes a hierarchical dispatching scheme for disaster relief materials, covering both dispatches between supply points and affected sites and dispatches among affected sites themselves. The proposed scheme is designed for post-disaster emergency material scheduling and explicitly accounts for vehicle dispatching preferences. This study makes the following assumptions:(1) after a sudden event, resources received from external regions arrive at multiple supply points in a time-staggered manner;(2) new demands from affected populations are generated at affected sites over multiple periods; and(3) under the hierarchical material dispatching framework, vehicle dispatching preferences are differentiated between supply points and affected sites. Based on these assumptions, an emergency material dispatching model is developed that integrates multi-period supply and demand satisfaction with coordinated allocation of materials and vehicles. Using post-earthquake emergency response operations in Dingri County, Shigatse Prefecture, Tibet, as an empirical case study, the paper examines the operational effectiveness, practicality, and potential advantages of the proposed hierarchical dispatching framework.
