Abstract: Under consideration of different characteristics for various subjects in emergency networks, as well as the interaction between the disaster risk environment and the relief resources allocation, a three-tiered supernetwork framework,is constructed consisting of retrieval depots, distribution centers and demand points, and its the network flows are the amount of allocated resources and the disaster risk degrees. By transforming this supernetwork to an equivalence structure, the emergency optimization objectives and disaster relief behaviors are formalized, and then they are represented as the complementary problem of a variational inequality for computational solution. Numerical simulation and sensitivity analysis demonstrate that some key parameters, e.g. the emergency capability limitation and the disaster risk degree, have important influence on decision-makings of emergency resources allocation.

Key words: emergency management, supernetwork, resources allocation, disaster risk, variational inequality
