Planning for Flood Evacuation: A Location-allocation Model with Shelter Capacity Constraints
Abstract:
The optimal shelter locations and flow allocations for the flood evacuation planning are examined in this paper. It is assumed that the authority can control the traffic in certain part of the network while the evacuees select which shelter to go and by which route. The location-allocation problem is formulated as bi-level program,
interpreted as Stackelberg game, consisting of the
leader (authority) and the follower (evacuees). The
authority determines the location of shelters to minimize the total evacuation time, and evacuees decide on shelter and route to evacuate simultaneously. The upper level sub-problem is modeled as location problem to represent the authoritys decision on shelter location. To represent evacuees decision, a combined distribution and assignment (CDA) model is proposed as lower level sub-problem. Due to difficulty of bi-level problem solving, heuristic algorithm, genetic algorithm (GA), is deployed to solve the problem. Numerical experiment with real world network is exemplified to demonstrate
the application of the proposed model.
