Super-network model of urban agglomeration emergency coordination considering decision preferences
A multi-tiered urban agglomeration emergency super-network model,constituted by retrieval depots,transit points and disaster-affected areas,is proposed in this paper against intercity disaster or resource limitation in a single city.The system-optimization goal of the model is established in terms of emergency time and cost.Stochastic choice in multiple emergency modes is studied based upon the stochastic user equilibrium assignment theory.The optimization goal and the stochastic choice problem are transformed into equivalent variation inequalities,respectively.By performing a numerical simulation and a computational solution,the feasibility and effectiveness of the model are demonstrated,in which key factors are analyzed for the decisionmaking practice.
