Abstract
According to the typical hierarchical structure of urban emergency shelters and also the population transfer pattern among these shelters, a hierarchical spatial model for urban emergency shelters under the multi-stream model has been developed in this research. Different from the single-stream model, where the affected population has to be moved step by step to the downstream level to access the relevant services, the multi-stream model allows the affected people to receive the lower-level services directly from the upper level. do The proposed high-rise shelter model is an extended model of the traditional single-stream hierarchical location model, and it is more consistent with the realistic situation of emergency shelter locations. In addition, it has been shown by theoretical and case analysis that the location solution resulting from the multi-flow model not only provides the effect of refuge but also saves resources and costs.
